High-Temperature HeatersHigh-Temperature Tubular Heaters Watlow manufactures high-temperature tubular heaters to bridge the gap between standard tubular heaters and Watlow MULTICELL™ heaters. This tubular 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 show an increase in life of approximately 50 percent. The high-temperature tubular consists of an engineered tubing with an outer sheath of alloy 600 and a special internal...

Ceramic Fiber Heaters Ceramic fiber heaters offer some of the highest temperature heating element capabilities available 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 are ideally suited for high temperature applications requiring low thermal...
