High Temperature Heaters
Ceramic fiber heaters offer some of the highest temperature heating element capabilities in the Watlow family of heaters. Heating units constructed of ceramic fiber insulation isolate the heating chamber from the outside. Ceramic fiber heaters are extremely low mass, high insulation value units with self-supported heating elements. Many applications can benefit from the convenience of the heating element and insulation combined into one package. Its lightweight, low-density properties make it ideally suited for high temperature applications requiring low thermal mass
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.
Watlow manufactures high-temperature tubular heaters to bridge the gap between standard tubular heaters and Watlow MULTICELL™ heaters. This high temperature heater is well suited for process air heating applications in excess of 1300˚F (704˚C), resulting in a maximum sheath temperature of 1800˚F (983˚C). Controlled lab testing between the new design and current tubular designs shows an increase in life of approximately 50 percent.
The high-temperature heaters consist of an engineered tubing with an outer sheath of Alloy 600 and a special internal construction. The outer sheath offers high temperature capabilities, reduced oxidation as well as corrosion resistance.
The advanced design of the MULTICELL heater from Watlow offers three major advantages over other insertion heaters: extreme process temperature capability, independent zone control for precise temperature uniformity and loose fit design for easy insertion and removal.
