This cartridge heater features a heating coil wrapped around a specially-selected ceramic core which is located close to the walls of the heater pipe. Its circumference is lined with extremely pure MgO (magnesia) for insulation, which is exceptional for its thermal conduction and insulation resistance at high temperatures.
The inside of the heater is structured to be perfectly compressed, so that heat from the heating coil efficiently travels outwards. This keeps the temperature difference to a minimum between the inside of the heater and the heater surface.
The heater can handle extremely high temperatures up to 1830ºF (1000ºC). The maximum watt density is 500 W/in2 (80 W/cm2).
