Mica Band Heaters

West Heat mica insulated band heaters are efficient and economical solutions to the heating requirements of many applications. Although their maximum sheath temperature is limited to 900°F, with different electrical termination styles, clamping mechanisms, and ability to accommodate holes and cutouts, our band heaters are successfully used in many applications.

Construction and features
- Economical
- Dependable and efficient
- High quality mica and resistance wire
- Versatile design
- CSA and CE certified

To maximize the surface-to-surface contact, our band heaters are carefully rounded and formed to optimize the grip on a machine barrel. The external metallic protective sheath is made of a special alloy, which expands less than the barrel when heated. This difference in thermal expansion makes the heater grip the barrel firmly once it is energized, and this improves heat transfer. Poor heat transfer acts like a throttle and makes the resistance element inside the heater function at elevated temperatures, which eventually leads to the premature failure of the heater.
West Heat band heaters are made in different construction styles, clamping mechanisms, and terminal types. Holes, cutouts, slots, thermocouple or mounting brackets can be accommodated in the design.
