Cartridge Heaters

Cartridge Heaters are available in round or square shapes in various sizes from 1/8 inch to 1-1/4 inch diameter to lengths that are only restricted by the diameter of the heater. Various lead styles are available to withstand constant flexing, washdown or extremely corrosive and moist environments.

Typical Cartridge Heater Applications:

  • Molds
  • Dies
  • Platens
  • Hot plates
  • Sealings Bars
  • Immersion Heating
  • Medical
  • Aerospace
  • Semiconductor
  • Foodservice equipment
  • Plastics processing
  • Heat sealing
  • Liquid and gas heating

Cartridge Heater Features:

  • Part temperatures to 1600°F
  • Swaged cartridge heaters with total quality control
  • Nickel chromium resistance wire precision wound
  • Magnesium oxide insulation of high purity and tight compaction
  • Incoloy sheath corrosion and oxidation resistant
  • Superior heat transfer due to minimum spacing between wire and sheath
