Don't lose time and money because of frozen propane tanks! The Powerblanket Lite 100 is an insulated band-style cylinder heater specifically designed to fit a 100 pound gas cylinder. The heater is built for use with 120 volts AC, drawing 2.33 amps thus producing 280 watts. It has a preset thermostat set for 90 ºF / 32 ºC (± 10 ºF / 5 ºC). This band style cylinder heaters allow you to draw propane at increased rates in cold weather conditions versus an unheated cylinder. You can run one band or add a second one further up the cylinder to improve the performance of the gas delivery system even more. This innovative heat-spreading technology insulates, protects and maintains heat to help you keep your pressure and BTU's up while reducing the frequency of cylinder refills.
