L Type Electric Cartridge Heater
Cartridge heaters is consist of a cylindrical stainless steel tube and thus provide a high corrosion prevention. The heating wire inside which is wound onto a ceramic core.
The number of coils varies depending on the power. and provide a great uniform distribution of heat, which considerably increases the long life of the heater as well as prevents the oxidation of the heater wire even at high temperatures .The solids, liquids, and gases need to be heated by cartridge heater, transmit heat quickly by conduction if the producer of the heat (the cartridge) is in direct contact with the heat sink (any solid, liquid, or gas). Widely used for manufacturing plastic and rubber parts in the car industry or in the food processing industry, etc they are also commonly found in the chemical, electronics, medical equipment, packing and nuclear industries.
Apart from our broad standard range we also develop and manufacture cartridge heaters according to your special demands.
