SPECIFICATION SHEET High Temperature FIREROD® Heaters Swaged Cartridge Heater Ideal for High Temperature Applications The Watlow® high temperature (HT) FIREROD® heater is specially designed for high temperature platen applications up to 1600°F (871°C). The HT FIREROD 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. 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 up to 1600°F (871°C) • Maximum watt densities up to 100 W/in2 (15.5 W/cm2) • Maximum voltage up to 277VAC to ground • Length tolerance: +0, -4 percent standard diameters; +0, -8 percent for special diameter Typical Applications • Thermo plastic • Super plastic forming of titanium aircraft parts • Diffusion bonding to laminate and shape titanium • High temperature glass forming Watlow® and FIREROD® are registered trademarks of Watlow Electric.
