HT FIREROD Cartridge Heaters

HT FireRod Cartridge HeaterSwaged Cartridge Heater Ideal for High Temperature Applications

The Watlow® high temperature (HT) FIREROD® heater is specially designed for high temperature platen applications up to 1800°F (980°C). The HT FIREROD heater utilizes the same industry leading design principals used on all of Watlow’s FIREROD heaters. 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.

The HT FIREROD is designed specifically for use in high temperature applications:

  • Internal seal construction is virtually airtight to reduce the effects of resistance wire oxidation
  • The high temperature sheath is treated to improve its emissivity for better heat transfer Performance Capabilities
  • 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
