Product Description
Cartridge heaters are a versatile and durable product that is used to heat many 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.

Chromalox
Chromalox Cartridge Heaters are highly compacted to produce excellent heat transfer capabilities and the dielectric and physical strength necessary for long life and outstanding performance. These cartridge heaters are designed for applications where high operating temperatures are required
Dalton Electric
Dalton Electric's Watt-Flex Cartridge Heaters use a unique, patented split-sheath design that allow the heater to expand when energized to maximize heat transfer through greater contact with the wall of the bore. Better heat transfer means less power is consumed to maintain the set point temperature, reducing operating costs The Watt-Flex heater construction eliminates ceramic cores typically found in conventional cartridge heaters. Dalton has developed highly-specialized manufacturing techniques to compact high-grade MgO dielectric to near its maximum density around the heater coil, which increases dielectric strength and heat transfer away from the coil, resulting in significantly longer heater life.
