How Can I Prevent My Propane Tank from Freezing?

How Can I Prevent My Propane Tank from Freezing?

Propane tanks will freeze up when the ambient temperature drops below -44°F. This is because propane has a boiling point of -44°F. If the temperature is not greater than -45°F, your propane will not vaporize, and your tank will freeze. However, as the temperatures drop, and the volume of propane in your tank drops, as will your pressure. If you do not have a heating source, it is important to keep your propane tank as full as possible at all times, to avoid freezing.

Pressure Rates

Another situation that can cause a propane tank to freeze up is pressure rate. Drawing more pressure than your tank is designed for, or pulling large amounts of pressure in a short amount of time will result in freezing.

Keep It Full by Keeping It Warm

You can prevent your tank from freezing by keeping it full, which means filling your tank more often. This option may be expensive and annoying.  Or, you can look into heating systems. When researching ways to heat propane, safety is key. Try to find a heating method with safe heat, such as a heating blanket, or an insulated blanket, depending upon the amount of pressure needed. It is important to know how many watts are necessary to obtain the PSI levels desired or required.  If it is not possible to calculate this yourself, you will want to look for a solution that can provide that information for you before you make the investment.  Look for a heating solution that offers consistent heat and complete coverage.

Remember This

  • If possible, protect your tank from the elements
  • When the temperature drops, the pressure drops
  • The molecules in propane move rapidly as temperatures increase and slow down as temperatures decrease
  • Maintain a desirable tank pressure and avoid freezing with a heating source

 

No Open Flames

It is always important to remember when searching for a solution, to avoid open flames. Do not, under any circumstances, warm your propane tank with an open flame.  Propane is a highly flammable gas and heating it can be extremely dangerous. Also avoid products that are not temperature controlled, overheating a propane tank can cause the pressure valve to blow, which will create a leak in your tank.

Freezing Temperature Solutions

Cold weather often has adverse effects on equipment and materials, especially when the job requires everything to go smoothly. Without an effective solution to these freezing temperature problems, projects stop, time and money are lost, and jobs suffer.

Increase Gas Flow Rate Solutions for You

Increase Gas Flow Rate

“How do I increase my gas flow rate?”  Search this question online, and you may get some of the answers below:

Pressure of the gas in a container is created by the number of collisions the molecules have with each other and with the surface of the container. Increasing the number of collisions will increase gas flow rate.

There are a few ways to increase the number of collisions.

  1. Add more molecules. More molecules in the same size container will increase the number of times molecules collide.
  2. Increase the temperature. Increasing the temperature will increase the speed at which the molecules move and therefore increase the number of collisions that take place in the container.
  3. Decrease the size of the container.  This forces the molecules into a smaller area, increasing the number of collisions that take place.

Assessing the Situation

Let’s assume that you already have the tank you want to use, and you are not interested in making any changes to the container/system.  Option 3 is out because it deals with changing the size of the container.  Let’s also say, to your knowledge, the tank is full and there are no more molecules to add, eliminating option 1 as a viable solution.  That brings us to temperature.

When the temperature is lower, it is very difficult to maintain an optimal gas flow rate.  Lower temperatures=fewer collisions in the tank.  This prevents the gas from vaporizing, rendering it virtually useless.  Propane, butane, nitrogen, oxygen and other compressed gasses need temperature control to ensure optimal gas flow rates.  Bringing the container/system up to a temperature above the cooler existing ambient temperature will result in increased pressure, flow and efficiency.

Heating Blankets to Increase Gas Flow Rate

Heating blankets are an excellent solution to increase temperatures for improved flow rates.  These blankets/jackets wrap around or lay over a variety of products and equipment to provide heat.  If installed properly, these apply heat directly to the medium, eliminating heat loss from exposed surfaces.  Heating blankets are easy to install and remove from the equipment requiring service.  They offer integral temperature control and heat larger areas with a lower temperature gradient.

Powerblanket® offers a variety of gas cylinder heating blankets for controlling temperatures of compressed gasses.  These heating blankets provide uniform heat for controlling temperatures of compressed gasses and a uniform barrier of heat across the entire cylinder.  This superior heating solution reduces cost by optimizing container temperatures and increasing gas flow rates.

Case in Point

A large semiconductor manufacturing company needed a new product to improve their semiconductor manufacturing process. They needed to maintain the flow of their gas delivery system more precisely, and their existing solution did not offer the consistency they desired.

Powerblanket designed a heating product for their gas delivery system that maintained the precise temperature and gas flow rate for hydrocarbon gases.

The company’s management team later admitted that they were initially against the idea of switching to the Powerblanket specialty gas heating solution. They said, “We didn’t think it would work because it was half the power of the status quo product, but after we gave it a try, we were immediately sold.  It’s a fantastic product and the sales and engineering support we received was excellent”

Another Example

Shannon Stillman, a Pyro Engineer at Thor Productions, said, “We use propane in large volumes – over ½ ton each night per event. Each of our cylinders are wrapped with a Powerblanket® Gas Cylinder Heater, extending the allowable duration by at least 60%. This equates to hundreds of usable lbs. of propane per night. In addition, the UL listing and safety ratings of the Powerblanket products resolve the concerns of the site safety managers, AHJ’s (Authorities Having Jurisdiction) and Fire Marshals.”

The Powerblanket Advantage

Powerblanket has the best gas cylinder heaters on the market. Our heating blankets will overcome the effects of cold weather and maintain pressure and efficiency on any gas cylinder.

  • Increase gas flow rate and efficiency of gas cylinders
  • Save money by optimizing gas and material usage
  • Eliminate unnecessary cylinder refills in cold weather
  • Insulated full-wrap design

Custom Tank Heaters: The Perfect Approach to Heating Solutions


custom tank heatersIt would be absolutely ridiculous to assume that all tanks come in the same shapes and sizes, whether they hold water, gas, chemicals, or some other matter. We all know that this simply isn’t the case. While there are certainly standard measurements for specialty gas tanks, water tanks, and others, the range of variance between size, construction, and purpose is vast enough that there simply isn’t a one-size-fits-all solution for tank protection. That’s why Powerblanket® Custom Tank Heaters are the perfect approach to the need for a heating solution.

 

Customized for Your Tanks and Needs

Regardless of the size of your tank, the purpose it serves, or its shape, Powerblanket can help you protect it against cold weather and keep it running at the ideal temperature year round. Our custom approach to providing tailored heating solutions to a myriad of industries and applications has allowed hundreds of customers to protect their precious assets from the ravages of cold weather.

In addition to freeze protection, our custom tank heaters enable increased efficiency in gas and other kinds of tanks. Anywhere flow rates and extraction rates are affected by temperature, Powerblanket custom tank heaters can ensure the flow of liquids and extraction of gas is always at its best. Take, for example, the nature of a gas such as propane.

When gases are stored in tanks, they are stored under considerable pressure. Due to this fact, they reside in the tank in both a liquid and gaseous state. Extracting a gas means you must evaporate some of the liquid and that evaporation process requires an input of heat energy. If the gas extraction rate is fast enough, it could cause the tank to frost up and the extraction to be impeded. However, with a custom Powerblanket propane tank heater you can keep the extraction flowing fast and full, without the side effect of frosting or icing.

What’s more, whether a tank holds gas or liquid, freezing temperatures pose big problems. Using a custom tank heater allows you to fully insulate and heat your tank to whatever temperature is best, regardless of the surrounding climate.

Heating and Hazardous Locations

Working in hazardous locations means you have to exercise serious caution regarding procedure, protocol, and equipment usage. What’s more, heating in hazardous locations takes all the more care and detail to make certain you aren’t adding fuel to a potential fire. This is why Powerblanket offers products certified to national safety standards.

 

CID2Class I Division 1 and Class I Division 2

We understand that hazardous location heating is nothing to take lightly. And we understand that heating products should be engineered to the highest standards of quality and safety. We’ve based our business on this simple reality and are able to customize our safe and innovative heating solutions to a myriad of industries because of it. In fact, our custom heating solutions can be designed and certified to Class I Division 1 (CID1) or Class I Division 2 (CID2) safety standards. We are certified for all four gas Groups, A, B, C, and D and up to a T4 Temperature Classification.  Many people who work in hazardous locations are familiar with these terms. For everyone else, here’s an explanation.

The classifications referenced as CID1 and CID2 regard the operation of electronic equipment in hazardous locations. CID1 is the identifier used for locations where ignitable concentrations of flammable gases, mists or vapors could possibly exist under normal working conditions. This classification also covers locations where the same gases, mists or vapors may exist frequently due to repairs or maintenance in the area. It also includes potential scenarios where gases, mists or vapors could be leaked by faulty or damaged equipment.

CID2, on the other hand, represents all locations where concentrations of flammable gases and/or vapors and/or mists are present in the air under operating conditions outside of the norm. So CID1 covers areas where such hazards are normally present, and CID2 covers areas where such hazards aren’t normally present but certainly could be under abnormal circumstances. Most importantly, if a product is CID1 or CID2 certified, it means that product is safe to use in locations that are CID1 or CID2 rated hazardous locations.

Powerblanket provides products that are certified to either of these hazardous location equipment safety standards. So when it comes to heating in hazardous areas, Powerblanket is both an efficient and safe choice. In addition to these ratings, Powerblanket products are also certified to UL, and CSA standards. Our innovative approach to providing industry-specific heating solutions has helped our customers save a lot of time and resources to safeguard and increase efficiency among the assets that keep their businesses running. So whether it’s freeze protection, viscosity maintenance, curing assistance, or some other heat-related dilemma, Powerblanket can help, even if you operate in a hazardous location.

Propane Tanks and How to Care for Them

Whether you’re a homeowner who relies on propane for heating, or a business leader who uses if for industrial purposes, propane is a versatile and important commodity. However, as helpful as propane is to us, we often overlook the need of caring for our propane tanks year round.

 

2016-01-05 09_16_31-Powerblanket___Propane_Tanks_Guide___v3__1_ (1).pdf - Adobe ReaderCaring for Your Propane: Tank and All

When it comes to caring for your propane storage, it’s imperative that you have a working knowledge of your tank and all the potential threats that could impede its proper functionality. Understanding the warning signs of a damaged or inefficient tank is important, not only for reasons of economical operation, but for the safety of all involved.

Several factors play into the safe and efficient operation of any size propane tank. These factors include, but aren’t limited to:

  • Shutting off valves when the tank is not in use
  • Keeping reserve tanks at a minimum
  • Not leaving portable propane tanks inside a vehicle
  • Securing portable tanks properly
  • Replacing weathered and/or worn canisters

Knowing how to properly manage all these aspects of propane storage and usage is very important. But there are many other factors to consider, too. Matters such as storage, setup, protection, government regulations, and the warning signs of hazardous circumstances are equally important.

Glass Blowing Heating Solutions for Flame Working

 

Glass blowing is a year-round pursuit for many. And when winter rolls around, it poses some obstacles for flame working. However, there’s no need to fear. You can protect your torch gases with a safe, efficient, and easy-to-use gas cylinder heater from Powerblanket®.

 

123The Powerblanket Gas Cylinder Heater

Whether you’re using acetylene or some other gas for your flame working torch, you’re probably well aware of the effect cold weather has on your gas storage. If you have to store your cylinders or tanks in an outside location (or in a cool warehouse) then you run the risk of severe depletion come winter, or even cooler fall and spring temperatures for that matter. Akin to the depletion your tank will undergo, is the lack of pressure you’ll have in it.

100 Pound Propane Tank HeaterPoor tank pressure means poor flow rates, and you can’t have that when you’re flame working. If the gas cools too much, it will liquefy, and you could potentially have acetylene spit out of your torch and into the amazing masterpiece you’re working. It’s end game at that point. Of course, to avoid this problem, all you have to do is keep your gas cylinders or tanks at the ideal temperature all of  the time. The only tricky part is that the ideal temperature for acetylene extraction is well above the cool temperatures of a non-heated workspace. Thankfully, there’s an easy remedy for this.

Powerblanket has developed gas cylinder heaters that keep acetylene, propane, butane, and any other specialty gas at ideal working temperatures, regardless of how cold it gets. The cylinder heater is easily applied to offer targeted and regulated heat to the cylinder contents. Most importantly, you don’t have to worry about heat and flame mixing (because that would be disastrous). Powerblanket products are fully insulated and are certified to UL and CSA safety standards. With particular relevance to torching applications, Powerblanket heating solutions are available with hazardous location certifications, Class I Division 1 or  Class I Division 2. This means they can be used in hazardous locations, such as a workshop where there might be or are flammable gases in the atmosphere.

Gas Welding: How Best to Regulate It

Whether you refer to it as oxy-fuel welding, oxy welding, or simply gas welding, it doesn’t come without its challenges. While gas-welding is one of the oldest forms of welding, and while it can be pretty straightforward and simple, regulating your gas flow can be tricky.

 

Gas WeldingA  Consistent Extraction Rate

When it comes to producing clean and flawless weld joints, consistent temperature of your gas is an important matter to regulate. Whether you’re using acetylene, hydrogen, propane/butane, or propylene, the answer is the same: you need to maintain an ideal temperature for a consistent extraction rate. And you need a consistent extraction rate in order to create pretty and efficient weld joints.

Controlling your welds can be as simple as controlling the one variable that you can control, and that’s the temperature on your gas tank. Of course, when we say you can control it, it’s because we’ve created a way for you to do so. Perhaps before now, you haven’t considered heating your gas tank, unless you have to weld in cold conditions, then it’s probably crossed your mind plenty of times.

420 Pound Propane Tank HeaterEither way, having the ideal temperature in your tank facilitates ideal gas extraction, which in turn, offers ideal welding. Heating your tank, especially when working in cold weather, will increase the PSI considerably. Of course, you don’t want the PSI too high either, and that’s why we use the term regulated heat. Maintaining the ideal temperature will help produce the best flow rate and will prevent pin holing and spattering.

Whether you use a small or large tank for your gas welding, we have a solution for you. There aren’t many heating methods on the market, except Powerblanket’s. With the Powerblanket® tank heater as a part of the equation, cold weather performance will be improved.

Gas welding in cold weather will wreak havoc on your gas cylinders. When the temperature drops, it’s very difficult to maintain optimal pressure in a gas tank of any size. This prevents the gas from vaporizing, which will produce a lousy flow rate, causing pin holing and spattering in your weld joints. Powerblanket® offers a variety of gas cylinder heaters for controlling the temperature of propane, butane, nitrogen, oxygen and other compressed gases. Powerblanket gas cylinder heaters provide heat where you need it. Our superior heating solution reduces costs by optimizing container temperatures and increasing cylinder efficiency. What’s more they are certified to meet UL and CSA standards with options for hazardous location certifications, class I, division 1 and class I, division 2.

Powerblanket® Specialty Gas Cylinder Heaters and Semiconductor Manufacturing

 

Powerblanket Specialty Gas Cylinder Heaters for Semiconductor Manufacturing

Powerblanket® gas heating products maintain specialty gas flow rates during semiconductor manufacturing.

It’s important for everything to be precise with the semiconductor manufacturing process. Contamination, temperature variance, and other variables can ruin the process. Powerblanket® products can play a vital role in maintaining specialty gas flow rates during semiconductor manufacturing.

Semiconductor Manufacturers Must Keep Gases Flowing Consistently by Maintaining Gas Temperature in Delivery Systems

Each semiconductor manufacturer has its own precise processes and carefully controlled conditions for producing semiconductors.  Many of these processes involve heating specialty gases to a precise temperature and maintaining the gas delivery system temperature throughout the operation. If the temperature of the specialty gas were to drop by as little as two degrees, the entire manufacturing process could be compromised.

While temperature isn’t the only factor, gas flow rates, are heavily dependent on temperature. Maintaining the temperature in the gas delivery system at the precise degree allows for consistent flow rates and uncompromised accuracy and consistency.

How Do Powerblanket Gas Cylinder Heating Products Help to Maintain Specialty Gas Flow Rates?

When it comes to the semiconductor manufacturing industry, Powerblanket products have a lot to offer.  Our specialty gas cylinder heaters and specialty gas tank heaters allow for precise and consistent temperature control. When paired with a temperature controller, Powerblanket specialty gas cylinder heaters can keep any gas, at the proper temperature for as long as needed.

A Short Case Study on Powerblanket and Gas Flow Rate Maintenance during the Semiconductor Manufacturing Process

A large semiconductor manufacturing company was searching for new products to improve their semiconductor manufacturing process. They needed to maintain their gas flow more precisely, and their existing solution (silicone heaters) was not consistent enough.

Powerblanket designed a specialty gas heating product that maintained the precise temperature and flow rate for hydrocarbon gases that the company was looking for.

The Company’s management team later mentioned that they were against the idea of switching to the Powerblanket specialty gas heating solution when it was proposed to them. They said, “We didn’t think it would work because it was half the power of the status quo product, but after we gave it a try, we were immediately sold…It’s a fantastic product and the sales and engineering support we received was excellent”

Ideal Temperature Control for Semiconductor Manufacturing

If you know anything about semiconductor manufacturing, then you know how precise everything has to be. There can be no contamination, no variance in temperature, and no room for error. That’s why Powerblanket® products play a vital role in maintaining ideal temperature for gases used in the manufacturing process of semiconductors.

 

Ideal Temperature Control for Semiconductor Manufacturing

Close Enough Isn’t Good Enough

Every semiconductor manufacturer seems to have their own recipe for producing their product. Whatever the processes, it’s certain to be very particular and stringent in nature. For example, heat-treated gases, purified for various processes in the creation on semiconductors, have to be able to maintain the ideal temperature for the duration of their function.

If a gas were to drop by as little as two degrees, the entire manufacturing process would be compromised. Temperature alone isn’t the only factor, however. Extraction rates have to be bang on form too.  Of course, in the end, extraction rates and flow rates ultimately have to do with temperature. Keeping the temperature of a tank of gas at the absolute perfect degree allows for consistent flow rates and uncompromised accuracy.

 

The Powerblanket Role in the Matter

The application possibilities of Powerblanket products are more than meets the eye. At least, we could say they’re more than the common person would think of upon first consideration. That’s why examples such as these are exciting for us to share. We love learning from our customers and sharing the myriad of applications and processes our products serve.

In regards to semiconductor manufacturing, our blankets allow for tight and regulated temperature control. With thermostatic controls built in, Powerblanket tank blankets can keep any gases, liquids, solids, or any combination at the proper temperature for as long as needed. So remember, if you can haul, build, truck it, or ship it, Powerblanket can cover it…literally.
