Low Watt Density Cartridge Heater

Pratik Heat Products manufactures Cartridge Heaters with premium materials and tight manufacturing controls. Cartridge Heaters ensures highest quality standards to provide superior performance and life expectancy at higher temperatures for many diverse applications. These are developed for heating applications not requiring high watt densities or sheath temperatures exceeding 3000° C with maximum watt densities of 30 to 45 watts per 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 4500°C. The 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.
