Highlights of Cartridge Heater

  • Cartridge Heaters are able to withstand tough industrial usage due to their special construction.
  • The heaters can achieve a watt density up to 200W/in2.
  • The nickel chrome heat wires are wound onto a ceramic core which is positioned inside the cylindrical metal sheath.
  • The heating coils are evenly spaced on the ceramic core to provide a uniform heat transfer to the sheath surface.
  • The power is controlled by the number of the heat coils.
  • The magnesium oxide powder are used as the insulating medium to avoid a short circuit.
  • The metal sheath is filled with the MgO powder.
  • The MgO powder is highly compacted through a special cold form process.
  • It makes the MgO powder very efficient to transfer heat inside the metal sheath.
  • Panshine’s cartridge heater are manufactured using the finest material and constructed with tight quality controls.
  • Panshine’s heaters provide superior heating performance, uniform watt densities and a long service life. They are also able to fitted with various thermocouples and sensors to your requirements.
