Even heat distribution ... with low power consumption

Thermal Shield™ Drum Warmers
The Thermal Shield drum warmer offers the most uniform distribution of heat available - while being the least expensive method to keep 55 gallon drums of liquid at operating temperatures or protecting them from freezing.

Thermal Shield drum warmers operate at a low 240 watts, compared to alternative "belts" that use 1000 watts or more. Our durable, light weight, insulated covering is ideal for indoor and outdoor use.

Calorique's design, proven over 15 years of Northern winters, can keep tank contents up to 50°F warmer than the ambient temperature (delta T).

Incorporating an integral insulating layer and durable vinyl outer jacket, the Thermal Shield's energy is almost entirely directed inward toward the tank's contents. Almost no heat is dissipated to the atmosphere as with other methods.

With over 10 square feet of heating area, Thermal Shield provides far more even heat than is possible with a "belt" only providing 2 square feet. This results in lower operating temperatures that can't scorch your liquid.

With the cover in place, our drum warmer reduces the need for  power by providing a completely insulated jacket for your drum. The cover even has a reinforced bung hole area that can be cut out if access to the contents is required while the heaters are operating.
