Ceramic Fiber Heaters
Ceramic Fiber Heaters Product Line
Ceramic Fiber Heaters combine an iron-chrome-aluminum (ICA) resistance element and ceramic fiber insulation to create heated insulation. Numerous stock, standard or custom shapes can be provided to solve high temperature, non-contact heating applications.
Low mass Ceramic Fiber Heaters permits applications to heat faster and run with cooler external temperatures. Embedded coil elements, or embedded or exposed flat or v-sinuated elements offer watt density variations. MODULE-MOUNT® mounting system permits easy custom furnace construction.
| Element Design | Maximum Watt Density | Maximum Operating Temperature |
| Embedded Coil | 5 W/in² (0.8 W/cm²) | 2200 °F (1205 °C) |
| Exposed V-Sinuated | 30 W/in² (4.6 W/cm²) | 2200 °F (1205 °C) |
Applications:
- High Temperature Furnaces
- Non-ferrous Metal Melting, Holding & Transfer
- Semiconductor Processing
- Glass, Ceramic & Wire Processing
- Fluidized Beds
- Laboratory & Ramp
Ceramic Fiber Heaters Product Line
The Ceramic Fiber Heaters Product Line offers some of the highest temperature heating element capabilities in the Watlow family of heaters. Ceramic fiber heaters are made by integrating an iron-chrome-aluminum (ICA) heating element and ceramic fiber insulation for a new concept in application problem solving. Heated insulation!
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. They're versatile for many applications that can benefit from the convenience of heating element and insulation in one package.
Ceramic fiber is an insulation made of an alumina-silica composition, held together by an inorganic binder. Its commonly used as a refractory material. Its lightweight, low-density properties make it ideally suited for high temperature applications requiring low thermal mass.
Performance Capabilities:
- Operating Temperatures up to 2200 °F (1204 °C)
- Watt Densities from 5 to 30 W/in (0.8 to 4.6 W/cm)
- Uses Radiant Heat Transfer Exclusively
Features:
- High temperature iron-chrome-aluminum (ICA) resistance elements are integrally bound into position. Five element configurations are available for your application.
- Lightweight, low 150 density alumina-silica composition is molded to shape, acting as insulation to insolate the heating chamber from the outside. This low shrinkage fiber and inorganic binder assures a firm, thermal shock resistant, self-supporting unit at all operating temperatures.
- Operating temperatures up to 2200 °F (1204 °C) provide high temperature performance not possible with many other heater types.
- Low mass ceramic fiber insulation of 10 to 15 lb/ft (160 to 240 kg/m) allows the heater to reach process temperature quickly and allows the energy to heat the load instead of wasting energy on itself.
- Works directly off common power-line voltages, eliminating the need for expensive transformers or complex power control systems. Compatible with the full range of Watlow temperature controls and power switching devices.
MODULE-MOUNT®
The MODULE-MOUNT® system examples presented here are for crucible and retort furnaces.
Also, represented here are floor and leg mounted configurations. Together this represents an overview of how the MODULE-MOUNT® system can be used in several typical applications, such as aluminum crucible furnace, retorts, vacuum tanks, fluidized beds, lead pots and more.
The cross-sectional illustration is to help you visualize the MODULE-MOUNT® system concept.
