HEATTEC Low Density Cartridge Heaters are also made of helically wound nickel chrome resistance evenly stretched and placed in ceramic insulators. It is then placed inside Brass or SS 304 tube. Magnesium oxide powder of high quality is filled inside the ceramic conductors. This would help to increase the thermal conductivity, dielectric strength and heater life.

 

  • Low watt density heaters are available in brass or SS 304 sheath.
  • Medium & High watt density heaters are available in SS 304 sheath.
  • Braided Wire, straight or right angle exit.
  • Uniform surface temperatures.
  • Flange type optional Braided wire.
  • Max temp for SS tube 400oC, for Brass tube 200oC.
  • Processing machinery.
  • Injection and Blow Moulding.

To increase the life of the heater, the clearance between the heater and bore diameter should be less. The inner diameter of the hole can be between 0.15mm and 0.30 mm larger than the cartridge diameter.

  • Diameter – Min 8mm to Max 45mm.
  • Length – Available in any desired length.
  • Max watt density 3.5 watt/sq cm.
  • For higher wattage and high temperature we recommend high watt density cartridge heaters.
  • Available in Teflon wire, fiberglass wire and nickel chromium wires. Insulated with ceramic beads or fiber glass sleeves.
  • From Dia 22mm onwards, screw connections are available
  • Send drawing or samples for any specific configuration
  • Fibre glass or tefflonwire crimped or welded to terminals.
