How Do I Keep My DEF Tote From Freezing?


How Do I Keep My DEF Tote from Freezing?

A DEF Tote is a portable solution for handling DEF that fits in the back of a truck bed. It is a combination of a 50 gallon specialized poly tank and a DEF Pumping system.  Many who use DEF store it in totes.  Some store it indoors, while others may keep their DEF outside year round.  DEF, because it is partly water, will freeze when temperatures drop.  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.  What is the best DEF tank heater for you?

Tote Heating Options


There are several ways to heat  DEF totes. Heat trace systems, which generally involve some form of heat tape, are costly to repair and replace. Initially inexpensive and available at most hardware stores, convenience is heat tape’s draw.  However, for something as large as a DEF tote, you would need A LOT to fully wrap your tote with heat trace. It doesn’t distribute heat evenly throughout the product either, since the heat is centralized on the tape and doesn’t really radiate. Heat tape is more functional on piping. Heated tape also has issues with wet weather conditions, leading to the expense of scraping it off and reinstalling new tape.

Electric heat blankets are typically a better option, but can be expensive to run, and traditional models still leave hot and cold spots. By looking at thermal imaging of the majority of heated blankets, you can see products run the risk of scalding or partially freezing.

Powerblanket DEF Totes are built on years of innovation.  Each blanket spreads heat evenly, covering the entire surface area of the DEF tote. They are cost-efficient and safe.

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.

“Upon implementing our new DEF system to stay compliant with EPA regulations, Powerblanket provided an effective and energy efficient freeze protection system with its DEF Tote Heater System.  We installed the unit and forgot about it, because we know our product is protected,” said Jerri Brumfield.

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.

Also 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

Keep Propane Tanks from Freezing with a Propane Tank Heater

If you rely on propane for year-round operations, then you already know what a headache winter weather can be. If you have a cold propane tank as a result of dropping temperatures, you’re going to lose a lot of efficiency. Thankfully, there’s a simple solution to keeping your propane tank from freezing, and the solution is something some refer to as a propane tank blanket.

Propane Performs Best Under Heat

Did you know that propane can freeze up completely if the ambient temperature drops below -44° F? Granted, -44° F is pretty darn cold, but in terms of gases, it’s a rather high freezing point. As cold as this temperature is in general terms, there are regions North America that experience extremes within this range and even lower, and if you operate a propane tank under these conditions without freeze protection, catastrophe is inevitable.

Worst-case scenario aside, propane tank efficiency will fall substantially as the temperature drops, even if it never plummets as low as -44° F. As the temperature drops, so does the pressure in your propane tank, and the pressure in your propane tank coincides with the volume of propane you have to work with. As pressure drops, not only will the volume of your propane deplete, but your extraction rate (how quickly and smoothly you can extract propane from the tank) will suffer as well. If you don’t have a heating source to assist in the pressure maintenance of your tank, then you’re going to have to keep it as full as possible in order to keep it working, even if temperatures are mildly cold.

More On Propane Extraction or Pressure Rate

Cold weather is the most common dilemma facing propane tank failure, but it isn’t the only one. Another cause of propane tank freezing has to do with the rate of extraction, or the pressure rate. If you’re drawing out a substantial amount of propane from your tank in a short amount of time, then you could cause the tank to freeze and ice up. This is assuming, of course, that you don’t have a heat source to assist with the problem.

Filling your propane tank more often isn’t going to solve a problem like this. And to be quite frank, it’s only a Band-Aid for cold weather dilemmas as well. No, the only real solution to both problems mentioned here is to keep your tank at the ideal temperature, regardless of outside forces. The safest, most efficient way to do this is to employ an external heating system that both insulates your tank and adds regulated and controlled heat to the exterior service.

In the case of heating propane, SAFETY IS MOST IMPORTANT. Propane, as we’re sure you know, is a highly flammable gas, so using any old make-shift solution isn’t safe. On the other hand, using a heating solution design specifically for the process, one that is certified and pronounced safe by reputable, third-party testing laboratories is the only way to go. With that said, let us introduce you to the Powerblanket Propane Tank Heater.
