Removable immersion heaters are designed to heat liquid in open tanks with low or variable liquid level, such as in degreasing baths process or surface treatment.

Removable immersion heaters consist of a moisture tight metal tube, with or without a screw head or flange, with a ceramic element inserted. The tube is in contact with the medium, meaning that the element heats indirectly.

Furthermore, a typical application area is situations where the heating elements need to be easily replaced, for example in tank heating, where one does not want to drain or drain the tank.
