Cartridge Heaters

In order to obtain optimum performance from these products, it is advised that temperature sensing and control elements be used with them.

Designed to provide localised heat to a restricted work area requiring close thermal control
Cartridge heaters have low/moderate watt density elements consisting of helical wire coils on ceramic former or high watt density elements with the heating element located close to the sheath, which is swaged to improve heat conduction
