The heater is built for use with 120 volts AC, drawing 3.33 amps thus producing 400 watts. It has a preset thermostat set to maintain up to a maximum 145 oF / 63 oC (± 10 oF/5 oC). The PBL55F full-coverage drum heaters allow you to safely control the temperature of expensive chemicals and other fluids; it delivers a barrier of directional heat where it's needed most, the bottom 2/3rds of the drum, while still insulating the top third to help retain the heat – preventing fluids from freezing and maintaining optimal temperatures. This innovative heat-spreading technology insulates, protects and maintains heat in a wide variety of applications. And it's certified by ETL to UL & CSA safety standards.Lessview less
