DHI Drum Immersion Heaters


Ideal for non-acidic materials, DHI Drum Immersion Heaters are designed to work in industries using 55-gallon drums, including oil and gas, agriculture, food processing, and more. The grounded immersion heaters are designed for maximum thermal efficiency, with a faster heat-up rate compared to standard full-coverage heaters when paired with an insulator. They feature food-safe construction and are safe for use on both poly or metal drums.


For easy installation, the heaters screw directly into the top of the drum. Both the heaters and insulators are suitable for use in wet or washdown environments.
