Metal Band Heaters are used to warm the contents of a drum or pail like a 55 gallon plastic drum heater or 5 gallon bucket heater. These heaters contain electrical heating elements inside a metal sheath. Before you use such a barrel warmer, you need to know what type of drum or pail the contents are in and what temperature the contents can tolerate.
Available in 4 different varieties:
For use on steel drums and steel pails with materials that are subject to charring, burning or separation: food, chocolate, honey, light oils, and undercoating materials.
A rugged aluminized steel housing that is equipped with a thermostat and resettable high limit cut off switch. When the water based material is reduced below the drum heater, the high limit switch will activate shutting off the heater.
