Viscosity Maintenance With the Proper Heating Solutions

Viscosity Maintenance With the Proper Heating Solutions

Drum heaters and barrel heaters are not only good for the cold months. In fact, they’re equally important for viscosity maintenance year round.

Drums Heaters and Barrel Heaters: Year Round Usesviscosity maintenance

Freeze Protection

Drum and barrel storage is a convenient way to maintain surpluses of all kinds. And when it comes to storing large amounts of material in such units during the colder months, the proper heating solution becomes imperative. Maintaining the ideal temperature range by using innovative heating solutions can also save significantly on the heating costs that go to your warehousing. But as much as all of this warrants the need for great drum heaters or barrel heaters, it only turns out to be half the equation.

Viscosity Maintenance

Drum heaters and barrel heaters work phenomenally well for freeze protection during the winter months. However, such technology is likewise helpful and necessary for year-round needs, such as viscosity maintenance. The patented approach behind Powerblanket® heating blankets is actually used for a wide range of heating needs.

Save Time and Money

Harnessing the ability to heat your liquids in the same container you store them in is a significant convenience, timesaver, and money saver.  Often times, manufacturers have to store products in a container entirely separate from those in which they heat the product. Of course, this means that you have to move the stored material from the storage unit into whatever container you use to heat it. In many manufacturing processes, this could represent a time-consuming step. Think, then, how great it would be if this was something that could be altogether avoided with the use of drum or barrel heaters.

What Powerblanket Can Do for You

Maintaining viscosityRegardless of what temperature-sensitive material you may be storing in your drums or barrels, if it needs to be heated for viscosity maintenance for proper manufacturing, then adding heat is a very important step in your preparations. And there’s no better way to add the heat than using Powerblanket insulated heating blankets?

Powerblanket drum and barrel heaters are simple to install, remove, and reinstall as needed, making the storage and transportation of temperature-sensitive product as efficient as possible, and making flow control solutions a snap.

DEF Freezing and DEF in Cold Weather

The Polar Vortex is sliding down over the country.  Have you taken precautions to prevent DEF freezing in the increasingly cold temperatures swiftly approaching?  We have tips and guidelines to help you with DEF in cold weather.

Understanding DEF and SCR

Diesel Exhaust Fluid (DEF) is a non-hazardous solution, which is 32.5% urea and 67.5% deionized water. DEF is sprayed into the exhaust stream of diesel vehicles to break down dangerous NOx emissions into harmless nitrogen and water. NOx is an element in exhaust that has been blamed for acid rain, smog and raising the overall greenhouse gas levels of the planet.  DEF is not a fuel additive and never comes into contact with diesel. It is stored in a separate tank, typically with a blue filler cap. This system is called Selective Catalytic Reduction (SCR).  SCR and DEF have been used for decades in other commercial and agricultural applications.

Storing DEF

DEF should be stored in a cool, dry, well-ventilated area. The ideal storage temperature for DEF is between 15ºF and 65ºF (-9ºC and 18ºC). It should not be exposed to direct sunlight for long periods of time as the urea will decompose. When possible, DEF packages and bulk storage should be kept indoors in temperature-controlled environments.  Use the right container. DEF is mildly corrosive, and should be stored in containers of HDPE plastic or stainless steel. 

DEF Freeze Protection guide graphic

DEF Expires

Check the expiration. The storage life of DEF varies. The urea is vulnerable to degradation from sunlight and higher temperatures. In favorable storage conditions (proper container, away from direct sunlight, temperatures between 15 and 65°F), DEF can maintain its qualities for about 12 months. 

Be Good to DEF

Handle it like fuel. Per EPA guidelines, vehicles using DEF must include sensors to continually analyze the quality of the DEF being consumed. These sensors will trigger a fault code whenever an imbalance is detected. Most commonly, this results from a higher percentage of water as a result of foreign matter, condensation or rainwater in the DEF storage container or during transfer.  The quality and integrity of DEF must be maintained for proper machine operation. It must be protected against evaporation and temperature extremes, and kept free of contaminants. Doing so could change DEF density, impacting its performance.

At what temperature does DEF freeze?

Quote on DEF standards

DEF, because of the urea, doesn’t have the freezing point of water. The urea mixture has a much lower freezing point of 12°F/-11°C. This solution doesn’t break into just urea and just water, either. The solution freezes at the same rate, and also thaws at the same rate. This means that at no point does the DEF freezing cause the solution to become over concentrated or diluted. DEF will begin to slush and then freeze.  There is no harm to the product which means that the urea solution is still safe to use if it has been frozen.

DEF Freezing and Expansion

Though it is safe to use again once thawed, expansion from freezing could cause problems.  Since DEF is a mixture of deionized water and urea, it reacts somewhat like water in that it does expand when frozen. DEF freezing usually causes about a 7% expansion. It is important to note that DEF freezing is usually taken into account when creating the packaging and tanks that are supposed to hold DEF. DEF packaging and tanks allow for expansion. However, one must be aware of the expansion of DEF when filling.  When storing equipment overnight or longer in temperatures that could result in DEF freezing, it is important to make sure the DEF tank on the equipment is not completely full or that it has an appropriate heat source. This will allow for expansion and help prevent cracking of the storage reservoir.

How to Prevent DEF Freezing?

DEF freezing was taken into account by the OEMs prior to creating the Selective Catalytic Reduction (SCR) systems. Therefore, the SCR systems are designed to provide heating for the DEF tank and supply lines; however, if the vehicle is shut down and exposed to freezing temperatures, then it is likely that the DEF will freeze. Diesel owners do not need to worry about DEF interfering with their vehicle, however. If DEF freezes when the vehicle is shutdown, startup and normal operation of the vehicle will not be inhibited. In most cases, the SCR heating system will quickly thaw the DEF in order to return it to liquid form and resume normal operation.


Can Anything Be Added to Prevent DEF Freezing?

Many want to know if anti-gelling or freeze-point-improver can be added to the DEF mixture to prevent freezing. DO NOT put additives into the urea solution because DEF must remain pure. The quality of DEF is extremely important for proper performance. Adding any additives would damage its ability to perform correctly and could even result in damages to the SCR system. No additives are approved for DEF at this time.

Caring for Your Diesel Exhaust Fluid

Diesel Exhaust Fluid, known for short as DEF, is a precious commodity to anyone running diesel-powered vehicles these days. Ever since 1970, when the Clean Air Act went into effect in the United States, the Environmental Protection Agency (EPA) has taken multiple measures to regulate exhaust from a myriad of vehicles. However, it wasn’t until 1990 that the EPA started mandating diesel exhaust specifically.


The Definitive Guide to DEFDEF: 1990 and Beyond

Since the inception of the EPA’s restrictions on diesel exhaust, DEF (Diesel Exhaust Fluid) has become all the more important. Emission standards have become more and more restrictive over the last two decades, and today, diesel exhaust restrictions are applicable to all on-road and off-road vehicles.

With these new restrictions in place, Selective Catalytic Reduction (SCR) systems are required to run diesel engines on any vehicle, whether a truck, a backhoe, or a combine. Eventually, these restrictions will also be enforced on water vessels. Essentially, with the EPA’s mandate in place, every diesel engine will eventually have to run a SCR, except for those built before the new regulations were in place.

Since SCR are a requirement of the present and future, DEF becomes nearly as essential as the fuel itself. And with DEF being as important as it is, it becomes imperative that you know how to properly store and care for it. DEF maintenance includes, but isn’t limited to:

  • How to use it
  • How to care for it
  • How to protect it
  • The challenges associate with DEF
  • Knowing the government regulations associated with it

You can learn more about all these matters and then some by downloading our free e-book through the link below.


DEF Tank Heaters: Storage and Beyond

If you run any sort of diesel engine, then you know how important DEF is these days. You can’t do business without it. However, wintertime poses a real problem to storing DEF. Then again, storage is only half of the problem. What do you do with your DEF in transit? Or worse yet, what do you do when your engine isn’t running. Thankfully, we have the answer with our DEF tank heaters.


Powerblanket DEF Tank HeaterDEF Tank Heaters

Protecting your DEF in storage is very important, but like we said already, it’s only half the problem. Protecting your DEF from freezing temperatures once it’s in the truck tank becomes equally important. The transportation and commercial trucking industries know just how frustrating it is when DEF freezes in the truck tank.

This problem has been around since the inception of Diesel Exhaust Fluid (DEF). But innovative truck manufacturers solved the problem by running their coolant system through the DEF tank. And it worked too, as long as the truck was running. That’s the catch, you see. This type of DEF heating solution only works when the engine is running. After parking a truck overnight in cold weather, the DEF could freeze up entirely. What’s more, it could take as much as 30 minutes to several hours of idling to thaw out a DEF popsicle. Running the truck with frozen DEF will likely trip the sensors too, indicating a false reading within truck computer and adversely affecting its performance.

Instead of taking a chance with winter, and losing valuable time as a result, trucking companies can turn to Powerblanket for an innovative solution to this dilemma. Powerblanket has developed an insulated heating blanket designed to fit the DEF tanks installed in commercial trucks. These DEF tank heaters offer both insulation and regulated heat that will keep your DEF at the ideal temperature. The Powerblanket DEF tank heater is certified to national and international safety standards and is easy to install, remove, and reinstall.

With options for either AC or DC voltage and the choice of a ten or fifteen-foot cord, our DEF tank heaters are easy to apply on your truck and plug in to keep your DEF warm when the engine isn’t running. So put the worry of frozen DEF aside this winter, and reach out to us for your DEF tank heaters today.

This year’s Mansfield D1 Expo was one of the biggest yet. Mansfield Oil is a national leader in the industries of energy supply, logistics, and services enterprise. As part of their focus on partnering with clients in order to provide innovative, technology-based solutions, Mansfield has put on this expo every year for six years now.

At this year’s sixth annual retreat for their partners, Mansfield offered plenty to capture participants’ interests, especially in regards to petroleum, ethanol, biodiesel, and DEF trends. The 2015 show had industry experts speaking about trends in the DEF and petroleum industry, it hosted showcased vendors of related products and services, and it focused on transportation & fuel additives. The show was packed with entertainment and information all.

Of all the matters addressed at is year’s show, DEF was a major focus. With Powerblanket DEF heating solutions present, participants and attendees were able to see firsthand the protective qualities of the Powerblanket solution. With DEF storage trending towards mini-bulk quantities as large as 600-4500 gallons for the trucking industry alone, the need to protect this valuable asset became all the more apparent at the Powerblanket booth.

“It was a privilege rubbing shoulders with so many experts in the DEF and Petro-Chemical industries,” said Justin Montoya, Powerblanket DEF Heating Solutions specialist. “We were thrilled with the interest in our products, including both DEF and our extensive product line for other applications.”



Further Contributions from Powerblanket

With the transportation and agricultural industries primed to start needing more DEF solutions, and with additional fuel additives complicating the process of viscosity maintenance, Powerblanket is ready to offer more than just DEF heaters.

Equally beneficial to the presence of Powerblanket DEF heaters at the Mansfield expo was the inclusion and discussion around the many Powerblanket heating solutions offered, DEF storage heaters being only one among many. Powerblanket provides a myriad of ready-to-ship heating solutions, but we also offer a completely customized approach to our heating technology. So regardless of what it is you need to warm or heat, Powerblanket has you covered.



Showcasing Our DEF Storage Heater at the Mansfield D1 Expo

The Mansfield D1 Expo offers a great opportunity for companies in the transportation and fuel industries to network and synergize their offerings and contributions. Powerblanket is present at this year’s expo to showcase the wonders of our DEF storage heater and other related technologies.


Mansfield Oil

This year marks the sixth annual running of the Mansfield D1 Expo. Mansfield Oil is a leader in petroleum marketing and fuel supply and puts this expo on to accommodate networking and support among those companies that drive success in the transportation and fuel industries. This year’s expo is a highly anticipated event with plenty to offer attendees and exhibitors. Industry and technological education, hands on exhibitions, and networking are all geared to help make the expo an unforgettable event.

Additionally, this year’s keynote speakers are said to be as anticipated as the event itself. Industry leaders will offer their insight on topics surrounding professional development and experience in the fuel industry.

The 2015 edition will support thirty-one exhibitors from around the country, all  of whom have come to present, share, and network their contributions to their respective sector. Powerblanket will be present to exhibit the company’s  DEF heating products as well as our wide variety of standard and custom heating solutions, each serving to help companies save time and money during cold-weather conditions. Of course, equally important to this is the increased efficiency that comes from using Powerblanket heating solutions.

Justin Montoya, Director of Business Development at Powerblanket, said that “having a presence at this event is great for us. The Mansfield D1 Expo is the perfect place to showcase and discuss the value of our innovative DEF storage heaters.”

Our patented approach to heat regulation and freeze protection enables companies to store DEF, and many other materials, at the ideal temperature, regardless of cold, frigid weather. We’ll be displaying and demoing our DEF storage heaters at our designated booth at the Westin Denver Downtown Hotel, located at 1672 Lawrence St. from August 24th through the 26th. Along with the DEF heating technology we’ll have on display, we’ll also be showcasing complementary smart controls. All this, plus our new Class I Division 1 certification and a raffle for prizes, makes the Powerblanket booth the place to be at this year’s Mansfield D1 Expo.



Winter Preparation: Now’s the Time

As the temperatures around the nation rise into the hundreds, cold-weather preparation may be the furthest thing from your mind. What’s more, there are plenty of warm-weather applications that Powerblanket technology is used for. But we would be completely remiss if we didn’t say enough of proper winter preparation. After all, when it comes to preparing for winter, you don’t want to be a grasshopper…

Aesop’s Fable: The Ant and the Grasshopper

Perhaps you’re already familiar with the old fable of The Ant and the Grasshopper from Aesop. If you’re not (and even if you are) we’ve recited it here. Below follows the most popular English renditions of the story:

“In a field one summer’s day a Grasshopper was hopping about, chirping and singing to its heart’s content. An Ant passed by, bearing along with great toil an ear of corn he was taking to the nest.

‘Why not come and chat with me,’ said the Grasshopper, ‘instead of toiling and moiling in that way?’

‘I am helping to lay up food for the winter,’ said the Ant, ‘and recommend you to do the same.’

‘Why bother about winter?’ said the Grasshopper; we have got plenty of food at present.’ But the Ant went on its way and continued its toil.

When the winter came, the Grasshopper found itself dying of hunger, while it saw the ants distributing, every day, corn and grain from the stores they had collected in the summer. Then the Grasshopper knew it is best to prepare for the days of necessity.”

Of course, the implications of this story can go far deeper than the need for good winter preparation. But for the sake of comparison, the story’s plot is rather poignant for the industries we serve. When cold weather does hit, it’s best to already have the systems and products you need in place to brave the effects of winter. So if you have assets to cover come late October, now’s the best time to start getting together the protection you’ll need.

Europe’s New Diesel Emissions Controls

Stringent emission controls on diesel have been in place in the US since the Diesel Emissions Reduction Act was put in place in 2005. But did you know they’ve been in place even longer in Europe? Diesel emissions controls have been on the rise in European countries ever since 1992.

Diesel in Europe

When it comes to diesel emissions controls, they really don’t get any tougher than those in Europe. Yet, as tough as they already are, they’re only going to get tougher. Plans are already in place to tighten restrictions for on-road vehicles, non-road vehicles, and even marine vessels. For any worldwide and/or European manufacturer, these new rules and regulations are of paramount importance. Or should we say that understanding the new rules is of importance.

Technologies in diesel efficiency and emissions controls have increased significantly over the past two decades. In some ways, these technological advancements have come as a necessity in order to answer the demands being placed on diesel-powered vehicles. But in another way, restrictions have increased because of the capabilities made possible by the advancing technologies in diesel engines and fuel additives. It turns out to be one of those chicken-or-the-egg things, and determining which came first could be a difficult matter to pin down.

Either way, the reality is simple: restrictions on diesel aren’t going to loosen. So for all those involved in the diesel industry, as well as all those involved in any way with vehicles powered by diesel, have the need to remain apprised of any changes and additions in regulatory measures. That’s why for the past eleven years Integer and AdBlue® have held their annual summit and forum to address matters related to diesel emissions restrictions. This year’s summit will be held in Brussels, Belgium from June 16ththrough 18th. The summit will discuss the industry’s future challenges and the progress it has made and continues to make.

AdBlue itself is a Diesel Exhaust Fluid (DEF). DEF is used in Selective Catalytic Reduction (SCR) systems for the after-treatment of exhaust gases. DEF, therefore, is one of the primary components used to maintain compliance with restrictions on diesel emissions. With a SCR systems and DEF, a diesel engine emits much cleaner exhaust.  Due to the heavy regulations implemented over the last two decades, DEF has become increasingly important and valuable to those running diesel-powered vehicles. Now, with regulations on the rise again in Europe, one can only imagine how precious a commodity DEF will continue to be, and how much it might be discuss at the upcoming summit.

Diesel Exhaust Fluid and the Marine Industry

As of last year, the EPA (Environmental Protection Agency) started phasing in the new regulations for diesel engines in the marine industry. Now nearly half way through 2015, diesel exhaust fluid (DEF) is all the more important, even required, for commercial vessels.


Yacht and other small boats in the ocean

An Increasing Need for DEF

The EPA started with their plans to implement new emission standards on diesel engines back in 1998. The first target was the commercial trucking industry. Then the new emission standards requiring selective-catalytic-reduction (SCR) systems moved outside of trucking to include off-road vehicles such as backhoes, tractors, dump trucks, combines, large generators, bulldozers, and other similar equipment and vehicles for land use.

However, more recently, the same emission standards have moved to include commercial water vessels. When the EPA passed the new standard back in 2004, with plans to phase into it over the next decade, the expectation was to require a reduction in the allowable amount of sulfur in marine diesel fuel by 99%. Such a drop would require not only a new design to diesel engines, but also a SCR that implemented diesel exhaust fluid (DEF) to aid in the reduction of sulfur.

Now with these regulations in full force, those in the marine industry have a new, very valuable asset to protect, and that asset is DEF. DEF has storage requirements that need to be adhered to in order to ensure its longevity and efficiency.

DEF is used in SCR systems in order to greatly reduce the level of toxins in the emissions of diesel engines. However, like many chemical liquids, DEF needs to be kept within ideal temperature ranges when in storage and transportation, or else its chemical qualities could be compromised. And it probably won’t surprise anyone to learn that the ideal temperature for DEF is well above freezing. However, the problem becomes how to keep large amounts of DEF protected from freezing during the cold months.


DEF Heating Solutions

Heating solutions for DEF have been around for a long time, but finding the proper and most convenient heating solution for this liquid can be tricky. Some tote, barrel, or drum heaters will heat to a high enough temperature, but will do so unevenly, causing cold and hot spots that could ruin your DEF storage.  This is why the proper heating solution for DEF protection needs to be able to deliver consistent, even, and regulated heat distribution. Such a capability will ensure that your DEF isn’t overheated in spots and under heated in others. Since DEF should never be heated to more than 86° F, careful temperature regulation becomes extremely important.

Along with meeting temperature regulation requirements, you’ll also want a solution that can fit the common DEF storage unit (with customizable options for the less common storage unit) both insulating and heating at the same time.  What’s more, when it comes to protecting large quantities of DEF in multiple storage units, you’re going to want a product that you can set and forget. In other words, thermostatic controllers will allow you to set the proper temperature and worry about it no more.



Regulations on Diesel Affect Mining, Construction, and Agriculture

The regulations on diesel emissions that were passed by the EPA (Environmental Protection Agency) back in 2010 have, no doubt, affected the commercial trucking industry. While these changes are positive, they did create a need for the use of a new products and procedures. Now this same effect looks to create a similar reaction in the construction and agricultural industries.


Tractor and Harvester in field

2014: A Year for DEF

If you read the last article we published on this topic, then you’ll know all about the new plans for selective catalytic reduction (SCR) systems. As of this year, SCR systems are required in all off-highway vehicles. A vast majority of the diesel vehicles that fall under this distinction belong to three primary industries: mining, construction, and agriculture.

This new regulation on diesel emission management has created the need for DEF (diesel exhaust fluid) in vehicles beyond the common commercial truck. Now backhoes, tractors, dump trucks, combines, large generators, bulldozers, and myriad of other equipment and vehicles have to use SCR systems requiring DEF.

With the higher demand of DEF and the need to keep large quantities on hand, construction, mining, and agricultural companies have to learn and implement all the best practices associated with DEF. For example, DEF has limitations when it comes to proper storage.

DEF is a non-hazardous, liquid material used in SCR systems to minimize toxic emissions from diesel engines. When in storage and transportation, however, this liquid needs to be kept away from possible contaminants and at the proper temperature to ensure it maintains its usual shelf life. The ideal temperature for DEF is above freezing. Since DEF is most often stored outdoors in tanks and vats, this means that companies will need to harbor heating solutions for their DEF storage.

Thankfully, third-party vendors have been providing solutions for DEF freeze protection nearly as long as DEF has been around.  The proper solution for DEF freeze protection should offer an even and consistent distribution of heat to the entire surface area of the storage unit. This will ensure that your DEF isn’t overheated in one spot while being under heated in another. After all, DEF should never be over 86° F, or its characteristics could be compromised.

Additionally, you need a solution that will fit the common DEF storage unit, both insulating and heating at the same time. Thermostatic controls are also important, allowing you to set the proper temperature range without worrying about overheating. And ultimately, you need to work with a vendor that can offer a customized solution, should you ever need to cover and heat an uncommon storage unit.

The New Regulations on Diesel Exhaust Fluid

Diesel exhaust fluid (or DEF) has been a mandate for large highway vehicles since 2010—helping to reduce the pollution emitted by trucks and buses by as much as 90%. But did you know that these same regulations are set to extend beyond highway vehicles? In fact, they already have.

The EPA and DEF

DEF is an additive used in selective catalytic reduction (SCR) systems. The need for such a product all started in 2001 when the EPA (The U.S. Environmental Protection Agency) announced that all large diesel-run trucks and buses would have to start using SCR in order to reduce the pollutants caused by diesel-exhaust emissions. This mandate was to begin with all 2007 vehicle models moving forward. Ever since this time, SCR systems have been the norm for long-haul trucks and commercial buses. However, the EPA doesn’t plan to stop there.

As of 2014, this same regulation now applies to off-highway vehicles too. Off-highway vehicles include anything operating an industrial or large-scale diesel engine. This would include things like construction vehicles (dump trucks, backhoes, bulldozers), and agricultural equipment like tractors, combines, balers, and others. As you can imagine, such regulations will spread the need for good DEF management to industries that haven’t yet needed to consider it.

What’s more, the EPA’s plans will require the same of the railroad next year. By 2015, trains and other large rail equipment will need to incorporate SCR systems and will have reason to plan for the proper storage and management of DEF. In the following year, 2016, the marine industry will have to comply with all the same guidelines.

DEF Is Now a Precious Commodity

Thanks to the EPA’s move to reduce the pollution footprint these vehicles have on the air around us, we can all breathe a little easier. And in addition to this, the EPA’s decision has also made diesel exhaust fluid a precious commodity. From here on, any company responsible for large industrial vehicles will also need to be responsible for large amounts of DEF. Simply storing the quantity of DEF needed to run a diesel fleet can be challenging enough, but the concern doesn’t only involve space.

When storing DEF, you also have to make sure it maintains the temperature needed to function properly once it’s in the SCR. DEF density is at its best viscosity between 12-72 degrees Fahrenheit. To keep DEF in its optimum temperature range, you’ll need a solution that can insulate your product, preventing freezing or overheating. Keep in mind that as these regulations move forward, managing your DEF storage effectively becomes imperative to operational consistency. In the end, caring for your DEF will directly affect your bottom line.

Mobile Transport and DEF Protection

If you’re transporting large quantities of product, then you know what problems cold weather can pose to your operations. Aside from your products themselves, you have your fleet to worry about too. If you’re running diesel trucks, then cold weather can pose a major obstacle to your DEF storage, and ensuring proper DEF protection becomes imperative.

DEF in the Cold

When it comes to storing DEF, you have to make sure it doesn’t freeze. This goes without saying, of course. But ask yourself this question: is my current solution for DEF storage adequate, inexpensive, and easy to use? If not, then there’s room for improvement, right? And if your DEF storage procedures are not taking freeze control into account, then you could be putting a very valuable asset at risk.

DEF does have a pretty low freezing point, 12° F to be precise. And while this excludes a lot of regions in the US (and around the world for that matter) as being danger zones for dysfunctional DEF, there are still plenty of regions that need to concern themselves with adequate DEF protection, such as the whole country of Canada, for example.

Protecting Your DEF Storage With DEF Heaters

Since the 2010 mandated regulations on diesel exhaust, the demand for DEF in the United States has only increased. If you’re in the DEF supply business, the important question now is how to keep your valuable product safe from the effects of cold weather. 


Powerblanket DEF storage heaterDEF Storage Essentials

Those familiar with Diesel Exhaust Fluid (DEF) are also familiar with the fact that it has to be stored within a reasonable temperature range. Unless you’re keeping it all in a well-insulated and well-heated warehouse, the winter months could pose some problems when it come to adequately maintaining your product.  (Even if you do have an insulated and heated warehouse, there’s still a much more energy-efficient way to store your DEF.)Here’s some helpful information from an additional source:


According to, “the shelf life of DEF is two years, if the fluid temperature remains between 15ºF and 65ºF (-9ºC and 18ºC). Where DEF is stored outside in bulk tanks or totes, then heating and cooling solutions are available to ensure it is kept within the correct temperature range, (”So for all of you who have to store your DEF outdoors, the big question is what to do during cold weather, so as not to compromise the life of your DEF. Well, that’s where Powerblanket comes in.

Industrial Heaters: Out With The Old – In With The New

Band heaters vs. full coverage drum heatersWhen it comes to freeze protection and heating technology, not all solutions are created equal when it comes to industrial heaters. In fact, some heating solutions are extremely outdated with technology dating back several decades. Today’s consumers are demanding products to be higher quality and they want them delivered faster than ever before.

With this increase in standards, businesses can’t afford to be stuck with old heating technology. Businesses that use older heating technology deal with uneven heating, dangerous heating elements, and the inability to customize for specific tasks.

Uneven Heating

One of the biggest complaints about older heating technology is uneven heating. Older technology uses a centralized heating unit that emits a lot of heat in one or two locations. The hope is that the heat will spread and keep the entire unit from freezing. This process doesn’t work if you have sensitive materials or a large area to heat. The centralized heat source gets really hot in one location, often burning product and materials. So if your business has sensitive materials and products, older heating solutions are not an option.

Electrical heating blankets with GreenHeat Technology™ are a newer heating solution that evenly distributes heat across the entire surface area. Blanket heaters eliminate hot and cold spots and safely regulate the temperature to keep materials and products from burning. Whether you’re looking for a drum heater, bucket heater, tote heater, pipe heater, tank heater, or valve heater; it’s important that the heat is spread out evenly.

Not Customizable

Businesses are scrambling, trying to keep up with a demanding marketplace. This means businesses need to find quick and adaptable solutions to their problems. Old heating technology like band heaters and space heaters are not able to meet the needs of modern industrial businesses. The dated technology of band heaters and space heaters limits their use to a few applications. If your business has odd shaped tanks or large surface areas to heat, older style heaters are not the answer.

The flexibility of electric blanket heaters allows them to be customized for almost any heating application. Custom heating solutions are needed more and more because standard heating products are unable to meet the needs of today’s industrial businesses. If you need to closely regulate the temperature of your products and materials or need to heat a large or uneven tank, electric heating blankets can be customized to solve your heating problem..


Older style heaters can be dangerous. Band heaters have an extremely hot surface area that will burn you if touched. The problem with this technology is once it’s turned on, it’s almost impossible to remove it without getting burned.

Heating blankets are a new heating technology that can be easily added or removed at anytime of the heating process. Electrical heating blankets use reliable, internal thermostats so once they’re turned on, you don’t have to worry about them over heating. Just plug them in and forget about them. When it comes to a safe heating technology, electrical heating blankets are a great heating solution.

Bulk Material Storage and Heating Alternatives

Powerblanket Bulk Material Storage and Heating AlternativesColder weather causes all sorts of problems while working in outside, ambient conditions.  It can be particularly troublesome when working with temperature sensitive materials.  Operations are transitioning from smaller storage containers, to pallet containers and large, bulk storage tanks.  Finding the right heating solution for bulk material presents a challenge.

One option is to store product and containers in a warehouse or shed and heat the entire building.  While this is an option, it is not effective or energy efficient.  Heating a separate building to store product can cost hundreds of dollars per day in energy alone.  It’s also really difficult to bring product and material up to temperature in a timely manner by simply blowing in warm air.


Here are five factors to consider when looking for a bulk material heating solution:


  1. Portability –  Look for a solution that will allow you to transport the material to different locations heated and protected.  A portable solution  will also allow you to heat your material while at a job site.
  1. Energy Efficient –  Find a solution that will maximize efficiency and retain most of the heat being generated.  Heating solutions such as blanket-type heaters are extremely effective and energy efficient because they have direct contact to the thermal load.
  1. Effective  –  Bringing material up to temperature in a timely manner is critical to most operations.  Time is money.  Having a direct heat source with great heat retentive properties will achieve this.  A blanket-type heater, which is also insulated, will achieve this.
  1. Temperature Control –  Sometimes having temperature control capability is critical to a successful operation.  Overheating or under heating can ruin product, render it unusable and cause downtime.  Find a heating solution that allows you to control the temperature based on your job-site requirement and product blend.
  1. Custom Design Capability –  Partner with a heating company that has in-house engineering and is willing to custom design a heating solution for your unique needs.  Take the time to do some research and collaborate with heating experts to determine what heating solution will best achieve your desired end result.

What You Need To Know About Diesel Exhaust Fluid (DEF)

What You Need To Know About Diesel Exhaust Fluid (DEF)Diesel Exhaust Fluid (DEF) is used to meet the strict US EPA emissions regulations for diesel engines. DEF is a fluid that is injected into a Selective Catalytic Reduction (SCR) system. The SCR technology uses an urea based DEF and a catalytic converter to significantly reduce the emissions of nitrogen oxides (NOx). The higher oxygen levels provided by DEF results in a more efficient combustion. This equates to clean nitrogen and water emissions and maximized fuel efficiency.

It’s important to note that the United States Environmental Protection Agency (US EPA) will limit NOx levels and will require North American trucks to be equipped with SCR after 2010.

DEF is stored in a tank onboard the vehicle, and injected into the exhaust stream by a metering system at a rate of 2% of diesel consumption volume. Newer trucks have storage systems available that will hold up to 20 gallons.

Selective Catalytic Reduction and Diesel Exhaust Fluid systems are really not that intimidating once you do some research and learn what you need to know about them.


According to RelaDyne, here are some key points about DEF:

  • If DEF is kept to temperatures between 15ºF and 65ºF (-9ºC and 18ºC), it will last a minimum of 1 year
  • Big bulk dispensers (1,000 gallons) have internal climate control systems
  • In colder regions, it is recommended to store DEF in a storage unit
  • In warmer regions it is recommended to store DEF in a shaded area.
  • There are new climate control systems, designed specifically for DEF



Why Is Diesel Exhaust Fluid (DEF) Required?

DEF gallon containerThe pollutants emitted from the exhaust of diesel engines are extremely harmful to our environment and air quality. Federal standards limit exhaust emissions of five pollutants:

  • Hydrocarbons (HC)
  • Nitrogen Oxides (NOx)
  • Carbon Monoxide (CO)
  • Particulate matter (PM, for diesel vehicles only)
  • Formaldehyde (HCHO)

NOx and PM are the two most harmful of these five pollutants. NOx is the main cause of acid rain and ozone layer reduction. PM is composed by minute carbon particles and other toxic substances.

The Environmental Protection Agency (EPA) set in motion a series of tier standards that will eventually require all operating vehicles on the road, as well as off-road vehicles, to be in compliance with tier 4 standards. The latter having everything to do with diesel exhaust.

According to DieselNet’s website, “On May 11, 2004 the EPA signed the rule introducing Tier 4 emission standards, which are phased-in over the period of 2008-2015. The Tier 4 standards require that emissions of Particulate Matter (PM) and Nitrogen Oxides (NOx) be further reduced by about 90%. Such emission reductions can be achieved through the use of control technologies – including advanced exhaust gas after-treatment- similar to those required by the 2007-2010 standards for highway engines.”

What this means is that all engines in use will need to be in compliance with these standards. Manufacturing new vehicles isn’t a problem, but what about vehicles produced prior to 2007?

One solution is to use Diesel Exhaust Fluid (DEF) and a Selective Catalytic Reduction (SCR) system. By using an SRC system in conjunction with DEF, 94% of harmful pollutants are eliminated from diesel exhaust.

DEF is non-toxic and has a shelf life of about one year. However, it is susceptible to fierce summer and winter conditions. DEF freezes at about 11 degrees Fahrenheit. To prevent DEF from freezing there are solutions available.

What are Storage Options for Diesel Exhaust Fluid (DEF)?

DEF toteDiesel Exhaust Fluid or DEF is a high purity chemical solution containing 32.5% urea mixed with high purity deionized water. It’s used to stay in compliance with the Environmental Protection Agency (EPA) stringent emissions requirements mandated in 2010. DEF is used in conjunction with a technology called Selective Catalytic Reduction (SRC) as an injection to reduce harmful NOx.

As with highway use the EPA has now mandated the reduction of NOx in off road use. Some of which include:

  • excavators
  • construction equipment
  • farm tractors
  • other agricultural equipment
  • heavy forklifts
  • airport ground service equipment

As well as utility equipment such as:

  • generators
  • pumps
  • compressors

With such a large and growing need for DEF product there is also obviously the need to store it properly. Several types of storage container options are available that range from 2.5 gallon buckets to 8500 gallon tanks, and everything in between. Purchasing DEF in the smaller containers is more expensive per gallon and typically used for emergency supply for trucks. The larger containers, or bulk storage tanks, are primarily used with very large fleets.  While the great bulk tanks are more cost effective per gallon (buying in bulk is always a bargain. Just ask the millions of Costco lovers around the world) they can be an expensive initial investment. This is why most DEF storage containers tend to be “mini-bulk” storage containers.

330 gallon totes and 55 gallon drums seem to be the trend with many companies right now. Both can be refilled easily and there are several equipment companies that offer electrical or pneumatic pump and hose systems that work well with these containers. There are also freeze protection solutions available for storage in extreme cold climates.

The important thing to remember is to keep your DEF contaminant free. DEF is not harmful to touch and if you get it on your skin you can wipe if off easily without worrying about chemical burns, but contaminated DEF can cause harmful side effects to your SRC system, which can be devastatingly costly to repair or replace. Proper storage and handling care is essential to prolonging the life of this important material.

How Long Will it Take My Powerblanket Product to Heat My Materials?

Ground thawing blanketIt’s a great question and one I get asked over and over. You would think that such a consistently asked question would merit a quick answer for it. Unfortunately, we have to ask our own questions first to give a good answer. I realize how odd this sounds but let me ask you this … do you know how temperamental the heat transfer process can be?

Allow Wikipedia to explain: “Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion and exchange of thermal energy and heat between Physical systems.” What this means to those of us who suffer with a non-engineer-type brain (yes, I do work with a few engineers and I have every right to pick on them once in a while!) is that there are many variable that contribute to how heat is transferred from one object to another. This alters the time frame of heating something to the right temperature.

Here’s a quick review on why the answer is different for everyone on the question of “How long will it take my Powerblanket product to heat my materials?” You see, heat transfers from one object to the next in one of three ways:

  1. conduction,
  2. convection and/or
  3. radiation.

So, here are the key factors to heat transfer:

  1. When heat transferrers using our products, it is typically happens through conduction. Not always, but most of the time. “Conduction is the transfer of heat between substances that are in direct contact with each other. The better the conductor, the more rapidly heat will transfer.” This means the snugger you apply your Powerblanket wrap –  without adding additional straps –  the better the heat will transfer.
  2. Another variable that will play havoc on heat transfer is wind. Heat hates wind. In almost all cases wind will swoop in and steal heat from just about anything. That is not to say a Powerblanket wrap won’t heat, but only that it could take longer to get it there.
  3. Ambient temperatures also play a determining factor in heat-transfer time. If the desired temperature is 70°F and your ambient is -20°F it will take quite a bit longer to get there than if your ambient was 65°F. Make sense? Of course it does.
  4. And, finally, what are you trying to heat and what is its beginning temperature? Is it thick and viscous or is it thin like water? Does it begin the heat process at frigid temperatures or something reasonable like 50°F? The more viscous the product the harder it is to circulate the heat throughout. (This is called convection.) “Heat energy transferred between a surface and a moving fluid at different temperatures is known as convection. In reality this is a combination of diffusion and bulk motion of molecules. Near the surface the fluid velocity is low, and diffusion dominates. Away from the surface, bulk motion increases the influence and dominates.”

So, now you see that this one simple question, “how long will it take to get hot?” cannot be answered quickly and there is not a one-size-fits-all answer.

How Do I Keep My DEF Tote From Freezing?


DEF tote heater“My [totes] are froze!” (101 Dalmatians)

Freezing is one of DEF’s (Diesel Exhaust Fluid) bigger problems. DEF is made up of a 32.5% urea solution and 67.5% de-ionized water and it may freeze at temperatures at or below 12°F. However, keeping the frost at bay is as easy as 1, 2, industrial electric blanket.

Storing and dispensing DEF in cold areas presents many challenges. DEF storage containers range from two-and-a-half gallon jugs to bulk systems that hold anywhere from 300 to 4000 U.S. gallons. Because these will freeze in cold weather, they need protection.  Additionally, if you’re using dispensers like a DEF pump or an electric tote pump, your product can freeze in the pump and hose. This prevents dispensing –even if the fluid in the container hasn’t frozen yet.

Cha-Ching! Pricy Alternate Solutions

Building an outbuilding to store DEF product can cost tens of thousands of dollars and use unnecessary resources. Many facilities also have to pay a premium on space, making indoor storage not feasible for many.

Powerblanket DEF Tote Heaters

Heating the containers with a DEF Tote Heater saves time and energy by only heating the unit and not an entire building. You will want to find a DEF Tote Heater that:

  1. Protects the pump and hose.
  2. Fully wraps around the entire tote and dispensing unit.
  3. Keeps the DEF at its optimal temperature while factoring in heat loss from wind and cold temperatures.
  4. Evenly heats so the DEF is not overheated in patches or left unprotected.
  5. Utilizes a thermostatic controller to monitor and maintain the proper temperature.

Stacks of IBC Tote ContainersAlso look for similar solutions if you keep your DEF stored in:

  • 330 gallon IBC Totes
  • 275 gallon IBC Totes
  • 55 gallon drums
  • 30 gallon drums
  • 15 gallon drums
  • 5 gallon drums

Whether you’re storing DEF, powdered milk, or toxic chemicals in your IBC tote, rest assured that Powerblanket has you covered…quite literally.
