Reasons You Need a Barrel Heater Other Than Freeze Protection


If your product will become compromised as the temperature of the ambient air drops below freezing, then a barrel heater is a simple solution to your dilemma. But what else can you do with a barrel heater? Most are aware that drum and barrel heaters keep products from freezing, but many are unaware of their other diverse functions.

The Barrel Heater: A Versatile Product

In the United States, during summer nights, temperatures can get as low as the 50s ºF. This really isn’t that cold, but in the case of highly sensitive chemicals and other finicky materials, this could lead to ruined, wasted product–and ultimately huge profit losses. In case you’re new here: lost money = bad.

Take a look at these six ways to use a barrel heater:

1. Melting and Preheating

If you have a product that needs to be brought from a highly-viscous or solid state to a liquid, a barrel heater might be your golden ticket. What you don’t want to have to do is transfer the product from its storage unit to some melting device. With an adequate barrel heater, you can melt and preheat your product to whatever temperature you need, while keeping it in the same barrel you store it in. Many food products can benefit from this.

One of Powerblanket’s customers is a soap maker who uses barrel heaters to warm up his soap oils for use every day. The barrel heater allows for slow, controlled heating without the danger of scorching product. The soap maker has found Powerblanket’s barrel heater to be the most efficient soap oil warmer on the market.

2. Temperature Maintenance

Maybe your case is a matter of temperature maintenance instead. This is often the case with certain resins, epoxies, and spray foam, even during storage. A drop below ideal temperature could compromise the nature of certain chemicals and other liquids. For example, epoxy must be stored at a specific temperature. If the epoxy gets too cold, it won’t be able to react with other chemicals for use later on. Barrel heaters prevent that from happening by providing consistent, evenly spread heat while in storage. 

3. Viscosity Regulation DEF

This use case is akin to the idea behind melting and preheating your product. If you have a product that needs to remain at a high temperature to avoid becoming too viscous, then you could drastically benefit from a product like a drum heating blanket. Diesel Exhaust Fluid, better known as DEF, needs to be kept at a temperature above freezing to prevent it from thickening and lessening its efficiency in diesel engines. Barrel heating technology allows DEF to stay above that point, taking that worry away from the minds of truckers and other large vehicle operators. 

4. Chemical Reaction Enablement

What if you could use your storage barrel or drum for chemical mixtures that need a certain level of heat? Well, you can. Barrel heaters can be very useful in providing heat for chemical reactions. One such product is epoxy. Epoxy must be heated to a specific temperature before mixing with other chemical reactants. Barrel heaters can be utilized to reach that temperature within a quick amount of time, getting the reaction going and the epoxy ready for use faster than using other options. 

5. Decontamination

In order for some liquids and resins to keep from becoming contaminated, they have to constantly sit at higher temperatures than room temperature. If this is the case with your product, you can easily accommodate this need through the application of an efficient barrel heater.

Need Custom Heating for Your Equipment? Answer These Questions

Do you need custom heating for a specific and unique application? Although there are various standardized heating solutions available, to determine the right solution, either standard or custom, a few initial questions need to be understood. The first of the discovery questions is to identify the desired result of the application which is generally one or a combination of the following:Custom Heating

  1. Freeze Protection:  Generally to protect from the elements or cold climate
  2. Temperature Maintenance:  Maintain a specific, constant and optimal temperature
  3. Added heat or Increase Temperature:  Add heat  and Increase temperature higher from starting point

For example, a pipe heating application may require higher energy/wattage to thaw a frozen pipe and then settle to a moderate power/wattage for continual freeze protection and flow control long term.

An epoxy/composite curing application may require pre-heating at higher temperatures prior to the epoxy being applied and then maintained at a higher temperature for optimal curing.

Begin with These Steps

  • Gather as much information as possible using the Custom Application Questionnaire. Be thorough.
  • The dimension needs to be as built, not a CAD drawing .  ALL dimensions must be submitted to the custom team for quote.
  • Once quote is accepted and PO is sent, engineering will begin.
  • Custom products will normally be completed within two weeks.

Custom Application Questionnaire

Once we understand the problem, these types of questions reveal the best solution:

  1. Which of these best describes the system requiring Cooling: drum/bucket, tote, tank, gas cylinder, pipe, flat surface (vertical or horizontal?), other?  
  2. Can you provide drawings and/or photos?  
  3. What are the critical dimensions of the system?  
  4. What material is the container or surface made of (i.e. tank wall, drum wall)? How thick? 
  5. What is the substance being Cooled (i.e. water, oil, pipe contents, concrete, frozen ground)? 
  6. Is this a flowing system? If so, what is the flow rate (include units, gpm, cfm, etc.)? 
  7. What is the expected ambient temperature (include units, °F, °C)? 
  8. What is the maximum expected wind velocity (include units, mpg, km/h, etc.)? 
  9. Are there other environmental conditions that may be relevant? 
  10. What is the beginning temperature of the substance or contents (include units, °F, °C)? 
  11. What is the desired final temperature of the substance or contents (include units, °F, °C)? 
  12. What temperature range is acceptable? 
  13. Are there upper or lower temperatures where the substance or contents will be damaged? 
  14. Is there a time frame requirement for the initial cool down? 
  15. What power source is preferred (120, 208, 240, DC)?  
  16. How far away is the power source (cord length)? 
  17. Do you require UL/CSA certified products? 
  18. Is your location considered hazardous (Class I Division 2)?
  19. How many units do you need now and in the future? 
  20. What is the required delivery date? 

Custom Heating Case Study

Powerblanket completed a project for a large chemical company to solve freeze protection problems. The company stores a chemical solution in large 4,000 to 8,000 gallon stainless steel tanks. Their customers live in various climates throughout North America. This solution is water based and freezes at roughly 32°F.  This company needed freeze protection and to maintain regular temperatures between 40°F -70°F.

The question became, “How do we provide a ‘one size fit all’ customized solution for various climates?” Powerblanket created a modular custom design, adjustable by region and tank size, that came in two pieces.

Powerblanket engineers calculated the amount of heat and insulation required to combat freezing temperatures and wind chill to maintain optimal temperatures in these various climates. What appeared to be a complicated application turned into a simple and effective custom solution.

So many industries need heating solutions, and not just during the cold months either. Epoxy curing, chemical storage, viscosity maintenance, food preparations, concrete curing, and much more all benefit from innovative temperature regulation year round.
