Fiber Insulated Heater combines a heat source with superior high temperature insulation - an ideal solution for many industrial heating applications. These heaters deliver fast,
efficient and reliable uniform heat to temperatures of 1250°C. Designed to deliver power densities up to 1500 watts/ft2, we are one of the most versatile embedded element radiant heaters
produced. OEM furnace and thermal process equipment manufacturers plus end users alike have embraced this combination heating and insulating system.
Ceramic fiber heater are available for immediate shipment from stock. Standard tolerance as shown for Alumina-Silica Insulation Type AXL is generally applied to the insulation and +/-5% to the
element resistance. Type "A" uninsulated double twisted lead wires, 9in. long are supplied as standard and positioned as indicated.
Ceramic Fiber Heater Characteristics
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 1100C.
They may, however operate at significantly higher power densities at lower temperatures and still provide
long life.
