The heating wire inside which is wound onto a ceramic core.
Cartridge heaters is consist of a cylindrical stainless steel tube and thus provide a high corrosion prevention.
The solids, liquids, and gases need to be heated cartridge heater, transmit heat quickly conduction if the producer of the heat ( the cartridge ) is in direct with the heat sink ( any, liquid, or gas ).
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.
Widely used for manufacturing plastic and rubber parts in the car industry or in the food processing industry, etc.
