Cartridge heaters

General description:

Cylindrical cartridges are an often-used form of heating element. They are usually inserted in a borehole in a metal part that is machined to fit, in order to heat larger machine parts. Also, Bach RC offers a large number of cartridge heaters. Compared with conventional metallic cartridge heaters, the ceramic heating elements are distinguished by having a very long lifespan, as well as a very high (achievable) power density (power output per surface unit). The dynamism of the heating process can thereby be improved and/or the number of the installed heating elements can be reduced. Machine failure times are minimised and so the productivity of your machines is increased. When installing the ceramic cartridge heaters in metal tools, the substantially lower thermal expansion of silicon nitride compared to metals must be taken into account.
