HEATTEC High Watt Density Cartridge Heaters are made of quality raw materials and advanced manufacturing process that ensures reliability in heavy duty working conditions like plastic processing, printing, packaging and automobile industries where the heaters are subjected to heavy vibrations. The perfect installation of the cartridge heaters facilitates good heat exchange between the surfaces of heater and mass to be heated thereby increasing the life of heater.

 

  • Sheathing material : SS 304 and SS 316.
  • Available with inbuilt Thermocouple ‘J’ or ‘K’.
  • Maximum sheath temperature 800oC.
  • Rugged & durable construction.
  • Highly compacted construction improves heater life and reduces the effect of vibration and shock.
  • Excellent heat transfer.
  • Plastic processing machinery.
  • Hot runner mould.
  • Packaging machinery.
  • Dies & moulds.
  • Shoe machinery.
  • Labeling machineries and a lot of other applications.
  • Food processing machinery.
  • Hot Stamping.
  • Heating gases and liquids.

The gap between the heater O.D and the bore I.D should be very close.

  • Fibre glass or Teflon wire crimped or welded to terminals.
  • Fibre glass wire with SS metal braiding.
  • Wires protected with SS or GI flexible conduits.
  • All wires are available in straight or right angle exit.
  • Drawing or sample required for special type terminals.
  • Fit = Largest hole I.D – Min heater O.D
  • Ex: Heater O.D = 12.5 mm (± 0.06mm std. tolerance)
  • Hole I.D = 12.6 mm (± 0.02mm hole tolerance)
  • Min heater O.D = 12.44 mm
  • Largest hole I.D = 12.62 mm
  • Fit = 12.62 – 12.44 = 0.18 mm (max permissible clearance)
Refer Operating temperature Vs Watt density graph to find max permissible clearance.
