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.
Cartridge heaters are made of crimped-on or swaged-in construction that consists in a high-grade nickel chromium resistance wire wound around a high-quality MgO core that is centered in a stainless steel casing.
Cartridge heaters are used for several heating metal parts and can be fitted with threaded bushings for liquid heating for certain applications. cartridge heaters will reach metal temperatures of up to 760°C with the appropriate material, watt density, and fit selections .

High Density Construction
High-quality stainless steel construction provides long-lasting protection even in the most rugged industrial environments
Protected with a stainless steel sheath, their watt density can reach 50 W/cm2 and their operating temperature can go up to 800°C.
Please consider the following factors in order to select the right cartridge heater.
Watt density of the heating element
Sheath material (corrosive or non corrosive)
Temperature of the corrodent
Degree of aeration of exposed corrodent
Velocity of the corrodent
