Cartridge heaters are an extraordinarily versatile and durable product that is used to heat a myriad different processes from heavy industrial – plastics and packaging applications to critical care medical devices and analytical test instruments to being used on aircrafts, railcars and trucks. Cartridge heaters are capable of operating at temperatures of up to 1400F and achieving watt densities of up to 260 watts per square inch. Available from stock or custom manufactured to your individual application need, they are available in many different imperial and metric diameters and lengths with many different style terminations, wattage and voltage ratings.

Cartridge heaters are an excellent choice to use as a conductive source for heating solid metal plates, blocks and dies or as a convective heat source for use in a variety of liquids and gases. Cartridge heaters can be used in a vacuum atmosphere with proper design guidelines.
