High Density Cartridge Element
Low, medium, and high-watt densities can all be used with cartridge heaters. They can sustain operating temperatures of up to 1400°F because of their design. The application for which you are utilizing the cartridge heater will determine the ideal operating temperature. When using cartridge heaters at relatively high temperatures, the electric terminals should either be unique from the usual high-temperature lead wires or the cartridge should be constructed so that the temperature around the lead wires is kept below the lead wire's maximum operating temperature.
