Cartridge Heaters, also known as cartridge heaters or cartridge-style heaters, are a type of heating element that is compact, efficient, and reliable. They are widely used in various industries and applications where heat is required for processes, equipment, and systems.

Cartridge heaters are typically cylindrical in shape and have a heating element that is coiled inside a metal sheath. The heating element is made of a resistive material that generates heat when electricity is applied. The metal sheath acts as a conductor to distribute the heat evenly and also provides structural support to the heating element. Cartridge heaters are available in different sizes, power ratings, and temperature ranges to suit different applications. They can be customized according to specific requirements, such as the length, diameter, wattage, and temperature rating. The most common materials used in cartridge heaters are stainless steel, incoloy, and incoly-nickel alloy.
