Flanged Immersion Heater

flange mount immersion heatersFlanged immersion heaters are easy to install and maintain. Designed for heating liquids and gases in tanks and pressure vessels, these heaters are a specific type of immersion heater which are ideal for applications requiring higher kilowatts.

Watlow flanged immersion heaters are made with WATROD or FIREBAR tubular elements brazed or welded to a flange. Stock flange heaters are equipped with a general purpose terminal enclosure. These heaters, with FIREBAR elements, also answer the need for liquid immersion applications requiring high kilowatts in small tanks.

The FIREBAR element’s unique flat surface geometry packs more power in a smaller bundle, with lower watt density, making it especially well-suited for petroleum-based liquid heating applications.

In addition to flanged immersion heaters, Hi-Watt Inc. carries a wide variety of other types of immersion heaters including over the side immersion heaters, and screw plug immersion heaters. Contact us today for more information on industrial heaters and how we can help you.
