Backer tubular heating elements can be cast in an aluminum alloy such as silumin.

Embedment of a tubular heating elements increases the heat-emitting surface and enables the element to be adapted to different applications.

Product examples

Standard heater plate

The heater plate consists of a Ø 8.5 mm steel tubular element cast into silumin.


Standard heat shield

The heat shield consists of a Ø 6.4 mm steel tubular element cast into silium. The shield is placed on the outside of the container, and heats up the fluid indirectly. Since the heat shield does not come into contact with the fluid, it is not subject to lime deposits or corrosion.
