Stainless Steel 150 W Single Phase Industrial High Density Cartridge Heater

A cartridge heater is a tube-shaped industrial heating element that may be inserted into drilled holes. Because they provide localised and accurate heating, cartridge heaters are commonly employed in the heating process industry. Cartridge heaters are widely used to heat a metal block from the inside, and they can be custom constructed to a specific watt density depending on the application. The most common use for cartridge heaters is to heat metal objects by inserting them into drilled holes. For simplicity of installation, the heaters are somewhat undersized in respect to their nominal diameter. A cartridge heater is constructed consisting of a resistance coil wrapped around a ceramic core covered in a metal sheath and surrounded with dielectric.
