LOW WATT DENSITY CARTRIDGE HEATER - DESCRIPTION
PHP’s Low Density Cartridge Heaters are developed for heating applications not requiring high watt densities nor sheath temperatures exceeding 300°C, 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 or machine.

The heater design consists of a 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. This alloy provides the best combination of physical strength and resistance to heat oxidation up to 450°C.

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.

The heaters are used in operations involving: packaging machinery, labeling machines, plastic injection, shoe machinery, heat sealing, hot stamping, glue guns and wax pots, heating of gases and liquids and various other heating applications.
