Immersion Heaters

Heatrex Flanged Immersion Heaters are designed for through-the-side mounting in tanks and pressure vessels using standard pipe flanges ranging from 3" to 14" in pipe size. They are available in a wide selection of rates, sizes and materials adaptable to the heating requirements of water, oil and other liquid solutions as well as air and other gases. They are readily installed through matching companion flanges (available from local industrial supply houses) which are welded to the vessel.

Flanged Immersion Heaters provide a high degree of efficiency since all the energy which is generated is dissipated directly into the medium which is being heated.

Construction

Standard Flanged Heaters consist of three or more hairpin shaped tubular elements welded or brazed into a carbon steel pipe flange. All standard flanges meet ANSI pipe flange specification B 16.5. Wiring is accomplished using heavy duty copper jumper straps and terminal connections designed to afford an extra margin of current carrying capacity. A NEMA 1 terminal housing is provided on all standard units. Many variations or modifications are available to meet specific application requirements.
