Powerblanket 20-pound tank gas cylinder heaters optimize container pressure and increase cylinder efficiency. Powerblanket products provide a maintenance-free heating solution, which eliminates the headache of maintaining critical temperatures. By using Powerblanket gas cylinder heaters, gas cylinders will last longer and be more effective. This saves time, hassle, and money.

Cold weather can wreak havoc on gas cylinders. When the temperature drops, it’s very difficult to maintain optimal pressure in a gas cylinder. This prevents the gas from vaporizing which in turn makes your gas cylinders unusable. Powerblanket offers a solution with gas cylinder heaters for controlling temperatures of propane, butane, nitrogen, oxygen and other compressed gases. These heaters provide a uniform barrier of heat across the entire cylinder with the help of a fixed internal thermostat.  Powerblanket 20-pound tank gas cylinder heaters come in three different thermal rating classes: 
  • Powerblanket Lite - designed for light residential and industrial applications, low power density
  • Powerblanket - designed for any definitive heating applications, surrounded by a rugged vinyl shell, safe to use in temperatures as low as -20 F
  • Powerblanket Xtreme - designed for harsh climates, safe to use in temperatures as low as -40 F

All of our tank gas cylinder heaters come as an insulated full-wrap design with cinch straps to secure a tight fit. They’re also water-resistant and can be used on poly and steel drums. All Powerblanket products are ETL certified to UL, CSA, and CE safety standards.

On those occasions when you don’t need all the extra strength and durability, however, there’s no use paying for more than you need, right? That’s why we created our Lite line. For those jobs that don’t necessitate the most robust and sturdy application possible, the Powerblanket Lite line is the best answer.

Cover Your Assets with a Powerblanket Lite Heating Solutions

Powerblanket Lite line is designed for heating jobs on a smaller scale. These models feature a lower power density than Powerblanket Industrial or Powerblanket Xtreme products. Rest assured that these heaters are the real deal! Keep your drums, barrels, buckets, pails and gas cylinder propane tanks warm in bitter climates so that you don’t lose any production time, saving you both time and money.

We live in Quebec Canada. We have winter that usually goes to -20F and we have seen -35F . So since we are using only propane for heating and did not know that below -42 the propane does not evaporate anymore. we decided to buy a Powerblanket for our 420lb tank in 2018 just to be safe. Last year (2018-2019) we had a very long and cold winter. We had a contract (2018-2019) for propane that was $130 per month for 12 months based on our 2017 usage We did have a very cold winter that did reach quite a few -30 to -36. We renew our contract in august and to our surprise, the contract for 2019-2020 is now $75 per month for 12 months based on the 2018 usage. Colder winter with less usage. We did not expected to be that good, but it is.
