Powerblanket 420-pound tank gas cylinder heaters optimize container pressure and increase tank efficiency. Furthermore, Powerblanket products provide a maintenance-free heating solution, eliminating the headache of maintaining critical temperatures. Moreover, by using Powerblanket propane tank heaters, gas cylinders last longer and operate more effectively, saving time, hassle, and money. Cold weather wreaks havoc on propane tanks and other gas cylinders. Consequently, when the temperature drops, maintaining optimal pressure in a gas cylinder becomes difficult. As a result, this prevents propane from vaporizing, rendering your propane tank unusable. However, Powerblanket offers a reliable solution with gas cylinder heaters designed for propane, butane, nitrogen, oxygen, and other compressed gases. These heaters provide uniform heat across the entire cylinder using a fixed internal thermostat, ensuring consistent performance.

Even with a lower power density, the Lite line still delivers reliable performance. Whether you’re heating drums, barrels, buckets, pails, or 420-pound gas cylinder propane tanks, Powerblanket Lite effectively keeps your materials warm in freezing climates. As a result, 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.
