Mini Coil Heaters

Hitco manufacturers high quality Mini Coil Heaters confirming to International Safety Standards and Performance. These are compact in design suits to high temperature needs in limited space / area.
Mini Coil Heaters can be manufactured to match specific requirement of end user application 
with built-in thermocouple type (J or K).Most of the regular sizes are available in stock.

 

Features & Advantages:

  • Voltage and wattage according to application.
  • With flat and square cross-section for high efficiency due to flat surface.
  • Choice of length of the heated respectively unheated zone at a maximum total length of 3000 mm.
  • With or without thermocouple.
  • Additional covering with clamping band or reflection tube
  • Coil heaters casted in brass having outer stainless steel sleeves
  • High corrosion resistance
  • Low profile construction
  • Maximum heat transfer due to more contact area.
  • Even temperature profile.
  • Precision fit on hot runner nozzles.
  • High watt density.
  • SS casting acts as a heat insulator.
  • Robust cast body can withstand pressure during leakage & avoids de-cooling.

Application

  • Hot Runner Nozzles & Bushings.
  • Die Casting Nozzles.
  • Tube Extrusion.
  • Pipe Forming.
  • Packing Machines.
  • Manifolds.
