Fits high-temperature radiant heating where you need Watlow ceramic fiber heaters rated to 2200 °F (1204 °C) with 5–30 W/in² and lightweight alumina-silica insulation.
Key advantages
- Temperature — Max operating 2200 °F (1204 °C)
- Watt density — 5 to 30 W/in² (0.8 to 4.6 W/cm²)
- Elements — High-temperature ICA; embedded or exposed sinuated (flat or V)
- Insulation — Lightweight alumina-silica ceramic fiber, 10–15 lb/ft³
- Geometry — Flat and semi-cylindrical; five element configurations
Typical applications
- High-temperature furnaces.
- Glass, ceramic, and wire processing.
- Low-mass chambers needing fast temperature rise.
Selection guide
- Geometry — Flat vs semi-cylindrical
- Element — Embedded vs exposed; flat vs V-sinuated
- Watt density — Process T and atmosphere
- Coating — Optional high-emissivity on high-W/in² series
Common mistakes
- Exceeding 2200 °F continuous rating.
- Using conductive/convective expectations — heat transfer is radiant.
- Ignoring atmosphere effects on ICA elements.
When to RFQ / what to tell us
- Chamber size, process T, kW/V.
- Geometry/element style; atmosphere.
- Quantity and ship-to.
