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.
