IMMERSION HEATERS: An Overview

Immersion heaters consist of tubular heating elements that are often in the form of a “U” or circular shape. Users can choose from several different immersion heater configurations and styles by selecting from an array of heating capacities (kilowatt ratings), voltages, sheath materials, terminal housings, thermostat types and extras.

The immersion heater elements are attached to a wiring box by using joining methods such as welding or brazing. The wiring box of such a heater typically is separated from the immersion solution via gaskets, bolt-on flanges, screw plug fittings, or an extension that allows the conduit box to hang over the side of the tank away from the immersion liquid.

along with being highly efficient, immersion heaters are available in a variety of sizes and shapes, which makes them  ideal for a wide variety of industrial or commercial applications. For instance, they are a good choice for the food and beverage sector to heat liquids such as water, oil, pulp or milk. Immersion heaters are also useful for freeze protection applications, and many different heat transfer systems make use of an immersion heater.

When ordering an immersion heater, there is an array of heater types, heating capacities (kilowatt ratings), voltages, sheath materials, terminal housings, thermostats and thermal cut-outs to choose from.

There are several standard products available to purchase from JobcoSupply.com; however, most manufacturers also offer a number of custom alternatives for the customer’s unique application. With expert engineering capabilities, immersion heaters can be made for use in corrosive or explosive environments and pressurized heating systems.
