HGC (Heavy Gauge Coil) Heaters

Highly cost-effective, long-life, heavy-gauge coil (HGC) unit heaters for semiconductor thermal processing

These HGC heaters usable at up to 1250°C of maximum working temperature are optimal as the unit heaters repeatedly perform comparatively high-temperature heat treatments for semiconductor diffusion furnaces. The heat sources using heavy-gauge coils are highly durable and realize long service lives.

HGC Heater

A combination of a heavy-gauge coil and patent spacer suppresses coil deformation. It is superior in high-temperature durability and achieves a long service life. The heaters are optimal for diffusion furnaces that repeatedly perform high-temperature heat treatments.

Features

  • A large number of interlocking coil spacers are arranged to support coiled heating elements.
  • Elasticity of the insulator prevents heating elements from being transformed.
  • The surface of the insulator is coated with zirconia to avoid particle generation.
  • Excellent heat-up and cool-down characteristics
  • Excellent high temperature stability
Applications Diffusion Furnace,
Oxidation Furnace,
Horizontal Furnace,
Vertical Furnace Disposer
