Product Details

ceramic vacuum fiber heaters /panel 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. It's lightweight, low-density properties make it ideally suited for high temperature applications requiring low thermal mass

Ceramic Fiber Heater technical date

Thermal Response

Power (watts) plus Hot & Cold Face Temperatures (°C) vs. Time for a test furnace composed of a custom cylindrical heater (6in. ID x 10in. OD x 6in. L, 1200W, 120V) with 2in. thick Alumina Silica Insulation Type AXL discs on each end.

Electrical Change

The electrical characteristics of these heaters change with temperature due to a shift in resistivity of the alloy used in the heating coil. At 1100°C there is a ~3.8% increase in resistance and decrease in current and power.

Safe Operation Zone

Fiber Insulated Heaters Type FIH are designed to operate at power densities up to 1500 watts/ft2 at 1100°C. They may, however operate at significantly higher power densities at lower temperatures and still provide long life.
