  • Engineered to achieve sheath temperatures up to 2050°F (1120°C)
  • Up to six independently controllable zones

Applications:

  • Hot isothermal forming
  • Soil remediation
  • Hot forging dies
  • Heated platens
  • Super plastic forming
  • Heated platens (single and multiple zones)
  • Heat treating processes
  • Super plastic forming with diffusion bonding
  • Polysilicon ingots
  • Hot gas generation

Features & Benefits:

Features Benefits
Multiple, independently controllable zones
  • Allows process temperature uniformity not possible with any other single-sheathed heater
Radiant design of heater
  • Allows for loose insertion in boiling holes and piping holes
  • Permits easy removal and replacement with minimal down time since it will not bind or seize in the hole
Oxidized sheath
  • Provides high emissivity and improves the heater’s performance as oxidation increases
Individually metal-sheathed coils swaged into a larger, high-temperature alloy outer sheath
  • Provides maximum protection against element burnout through the outer sheath
Quick disconnect plug and jack
  • Permits fast replacement of individual elements while the press stays at operating temperature
Special bending capabilities
  • Solves unusual machinery needs and keeps leads away from heated zones
Flexible leads up to 842°F (450°C)
  • Protects termination from high-temperature environment
