GreenHeat Technology is a heat-spreading system designed to deliver a highly efficient and uniform distribution of heat. The blankets are flexible enough to cover anything from 20-pound propane tanks to 30,000-gallon water tanks. Powerblanket tank wraps are available in configurations requiring 120V or 240V electricity and are certified to meet UL 499 and CSA C22.2 No. 130 standards.
