Scope of application - Cartridge heaters with ceramic heating elements

Cartridge heaters by HERBST are used for preheating lubricants for gears as well as thin oils such as heating or hydraulic oil in tanks and vats. Cartridge heating elements are also suitable for thermal oil applications and to heat turbine oil.


The advantage of the use of cartridge heaters is that the ceramic heating element can be exchanged any time without drainage of the medium since the protection tube remains in the tank.


The protection tubes are fastend by a welded thread nipple and a propper seal. Another option is the flange connection for mounting. More information about this product can be seen in the category Öffnet internen Link im aktuellen FensterFlange immersion heaters | FHK-P series.
