ANSI Flange Immersion Heaters

ANSI Flange Immersion HeaterWatlow® flange heaters, with IECEx and ATEX Ex'd' certification, are easy to install and maintain. Designed for heating liquids and gases in tanks and pressure vessels, flange immersion heaters are ideal for applications requiring higher kilowatts. Watlow flange 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. Watlow flange heaters possess IECEx and ATEX Ex'd' ratings certifying that the flange heater enclosure is flameproof. Every enclosure is pressure tested to ensure heaters are safe and reliable and meet rigorous standards for electrical safety. Flange 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.
