PHP’s High Watt Density Cartridge Heaters are designed and manufactured out of experience of many years, thus the performance and life expectancy superseeds other cartridge heaters.

Heating Conductor grade NiCr 80:20 is evenly wound over a supporting core which is centrally located in a SS321 tube and the inner space is filled with specially selected high purity magnesium oxide. This assembled unit is then highly compressed, converting the core, powder and conductor into a homogenous mass. The bottom end of the heater is welded with a disc washer to prevent contamination.

PHP's Low Density Cartridge Heaters are developed for heating applications not requiring high watt densities nor sheath temperatures exceeding 450°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 321 stainless steel sheath. 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.
