High Density Cartridge Heaters

High Density Cartridge Heaters are made of nickel chromium resistance wire wound on MgO care. The element assembly is inserted into chrome nickel steel tube centrally and filled with MgO powder. It is then compacted into a solid mass by Swaging. Swaging increases thermal conductivity, dielectric strength and heater life.

Low Density Cartridge Heaters

Low Density Cartridge Heaters are developed for heating applications where sheath temperatures not exceeding 3000c with maximum watt densities of 30 to 45 watts per square inch depending on applications. The heaters of various sheath diameters can be used in any assembly equipment of machine.

The heater design consists of helically wound resistance coil made from nickel-chrome wire, evenly stretched and strung through holes in a round ceramic insulator. The element assembly is inserted into a Chrome Nickel Steel sheath. This alloy provides the best combination of physical strength and resistance to heat oxidation up to 4500c.

Specially selected grain size and high purity magnesium oxide is used to fill all remaining space inside the ceramic insulator to increase thermal conductivity, dielectric strength, and provide longer operating heater life.
