| Detail | The Watlow HT FIREROD cartridge heater is especially designed for high-temperature platen applications up to 1600°F (871°C). The HT FIREROD high temperature cartridge heater utilizes the same industry leading design principles 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:
-HT FIREROD cartridge heaters are specially constructed with an end seal that is virtually airtight to reduce the effects of resistance wire oxidation |
