Screw Plug Immersion Heaters

Screw Plug Immersion Heaters consist of tubular elements welded or brazed into a threaded screw plug which can then be inserted into a threaded opening in a tank wall or through a mating full or half coupling.

Cartridge heaters are an excellent choice to use as a conductive source for heating solid metal plates, blocks and dies or as a convective heat source for use in a variety of liquids and gases. Cartridge heaters can be used in a vacuum atmosphere with proper design guidelines.
