Coil Heater

High-performance coil heaters are characterized primarily by their low intrinsic mass at a very large power density and low space requirements.

Pipe cartridges are used to heat:

  • Hot runner nozzles with and without heat distribution
  • Hot Runner Distribution Bar
  • Welding beams and sealing heads of packaging machines
  • Nozzles in the plastics and foundry industry
  • Plate heating and mould heating in mechanical engineering
  • Air heaters for Vernietvorrichtungen or biomass ignitions

General Specification:

  • Dimensions of the heaters from Ø 1.3 mm to Ø 8.6 mm
  • Round, square and rectangular shapes
  • Temperature-tight to a maximum of 750 °c on the cartridge sheath
  • temperature in the connection range max. 260 C °
  • With integrated temperature sensor type K/J or Mitgewendeltem jacket thermocouple
  • High voltage fixed up to 800 V (1250 v)
  • Reflection tube or tensioning strap also for large diameters
  • Suitable for inserting in plates and shapes
  • Total length heated stretched max 3000 mm
  • Connection variants with protective conductor, glass silk insulated protective hose, metal link HOSE, Drahthohlgeflechtschlauch
  • Heaters can be inserted into supplied plates with functional testing. The appropriate Nutprofil is available on request.
