PBL20: The PBL20 is an insulated band-style cylinder heater specifically designed to fit three different common gas cylinders. It can be used on standard 20, 30 or 40 pound gas cylinders. You can use one heater on the 20 or 30 pound cylinders and either one or two on the 40 pound. The heater is built for use with 120 volts AC, drawing 1 amp thus producing 120 watts. It has a preset thermostat set for 90 ºF / 32 ºC (± 10 ºF / 5 ºC). The PBL20 band style cylinder heaters allow you to draw propane at increased rates in cold weather conditions versus an unheated cylinder. This innovative heat-spreading technology insulates, protects and maintains heat to help you keep your pressure up and reduce the frequency of cylinder refills. 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! They are more efficient and safer than other heating elements on the market and certified to ETL, UL, CSA & CE safety standards. Keep your drums, barrels, buckets, pails & gas cylinder propane tanks warm in bitter climates so that you don't lose any production time, saving you both time and money. 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.
