Powerblanket 40-pound tank gas cylinder heaters are designed to optimize container pressure and significantly increase cylinder efficiency. Moreover, Powerblanket products provide a maintenance-free heating solution, which effectively eliminates the headache of maintaining critical temperatures. As a result, by using Powerblanket gas cylinder heaters, gas cylinders last longer and perform more effectively. Ultimately, this saves you time, hassle, and money.

Cold weather can wreak havoc on gas cylinders. Specifically, when the temperature drops, it becomes very difficult to maintain optimal pressure inside a gas cylinder. Consequently, this prevents the gas from vaporizing, which, in turn, makes your gas cylinders unusable. To address this issue, Powerblanket offers an innovative solution: gas cylinder heaters. These heaters are specifically designed to control the temperatures of propane, butane, nitrogen, oxygen, and other compressed gases. Furthermore, these heaters provide a uniform heat barrier across the entire cylinder with the help of a fixed internal thermostat, ensuring consistent performance.

Thermal Class Ratings

Powerblanket 40-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

Durable and Certified Design

In addition to their exceptional performance, all of our tank gas cylinder heaters feature an insulated full-wrap design with cinch straps for a secure fit. Additionally, they are water-resistant and compatible with both poly and steel drums. For added peace of mind, all Powerblanket products are ETL certified to UL, CSA, and CE safety standards, ensuring safety and reliability in every use.

    Lightweight Solutions for Smaller-Scale Heating Tasks

    For jobs that don’t require the most robust heating applications, the Powerblanket Lite line is the perfect solution. These gas cylinder heaters, for gas cylinders from 20-pound tanks to 1000 pounds,  are specifically designed for smaller-scale heating tasks, offering a lower power density compared to the Industrial or Xtreme models.

    Reliable Performance in Freezing Conditions

    Despite their lightweight design, Powerblanket Lite heaters effectively keep gas cylinders, propane tanks, drums, barrels, and buckets warm, even in freezing temperatures. This ensures uninterrupted production, helping you save 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.
