High density cartridge heaters

Cartridge heaters in high density versions deliver a very high power relative to their size and provide uniform heat distribution across the element’s outer sheath. The cartridge heaters have high tolerance to vibration and impact and are made airtight which significantly increases their working life. IHP sells cartridge heaters in all versions. The elements are typically used for heating tools i.e. heating of metal objects and mounted often in drilled holes. We design according to your demands regarding terminations, threads, plates, flanges, etc.

Power tolerance + 5% – 10%
Standard cold areas 5-25mm

Construction

IHP high density cartridge heaters are manufactured using a method where we compress all internally components with magnesium oxide to achieve a long life for all cartridges. A heating wire is spirally wound on to a hard ceramic cylinder or placed in holes within the ceramic cylinder depending on the heat intensity. Discs and ceramic heads are placed in both ends to isolate and protect the heater. The whole unit is sealed in a metal tube and packed in pure magnesium oxide to insure that everything is completely insulated. The cartridge heater is then compressed to the correct dimensions and tolerances.

Cartridge Heaters Construction

  1. Welded water proof base to withstand pressure up to 60kg/cm².
  2. Calibrated stainless steel tube in AISI 304/316/321/INCOLOY.
  3. Ceramic disc insulator.
  4. Pure magnesium oxide.
  5. Nickel-chrome 80/20 heater wire, melting point 1400°C.
  6. Ceramic core.
  7. Hard ceramic head.
  8. Conductor lead.
  9. Heat refracting paste.

Application examples

  • Heating of tools
  • Heating of solids
  • Heating of fluids
  • Molds
  • Melting
  • Hardening
  • Vulcanization
  • Welding
  • Medical and laboratory equipment

IHP high density cartridge heaters are made to withstand the toughest working conditions. Vibrations, moisture environments, direct fluid, frequent expansion and where temperatures between 400°C and 750°C are required.

When solids, gases and fluids are to be heated by electric energy the process is generally carried out by conduction. It is a proven method to quickly transmit heat by conduction if the cartridge heater is in direct contact with the piece to be heated (any solid, gas or fluid).
