High Temperature FIREROD® Cartridge Heaters 

The Watlow HT FIREROD® cartridge heater is especially designed for high temperature platen applications up to 1800°F (980°C). The HT FIREROD high temperature cartridge heater utilizes the same industry leading design principals used on all of Watlow's FIREROD products. Taking the cartridge heater one step further enables the HT FIREROD to withstand application temperatures up to 400°F (204°C) higher than standard cartridge heaters.

There are certain differences in the HT FIREROD design which are important in high temperature applications:

Specifications:

Material Maximum Operating Temperatures Maximum Watt Densities
°F °C W/in2 W/cm2
Incoloy®  1800 982 100 15.5
  • Platen temperatures to 1800°F (980°C)
  • Maximum watt density to 100 W/in2 (15.5 W/cm2)
  • Maximum voltage 277VAC to ground
  • Length tolerance: +0, -4 percent standard diameters; +0, -8 percent for special diameter

Applications:

  • Thermo plastic
  • Super plastic forming of titanium aircraft parts
  • Diffusion bonding to laminate and shape titanium

Features & Benefits:

Features Benefits
High temperature seal
  • Reduces exposure to the atmosphere which minimizes oxidation of the winding wires, resulting in longer life of the element Note: First 2 in. (51 mm) must be outside the platen in free air.
Incoloy® sheath
  • Transfers heat more efficiently
High emissivity sheath
  • Provides better heat transfer and longer life
