Plastic processing requires high operating temperatures and fast production rates. The Ceramic Band Heaters are designed to meet these demands. These heater are, in effect, high temperature electric furnaces capable of very efficient heat transfer by radiation, conduction and convection. Built-in insulation minimizes unwanted temperature changes along the barrel.

Other types of band heaters are primarily conductive, requiring an intimate fit with components
being heated. Grooves or other surface irregularities form voids under the bands, resulting in
hot spots and premature heater failure. Ceramic bands are recommended here because efficient
heat transfer is not affected by irregular surfaces or loose fit. At higher watt densities they can
be used in wider increments than other heaters. This means you can reduce the number of bands
used and simplify wiring.


  • Insulation Plus employs an additional 1/4″ of thermal insulation encased in a separate flexible stainless steel shell
  • Standard 1/4″ thick thermal insulation found on all ceramic band heaters.
  • Helical nickel-chrome coil for extended service.
  • Ceramic coil supports.

 Some Typical Insulation Plus Designs

  • Stud Terminals in Low Profile Box (1″ High) With BX installed
  • Stud Terminals in Standard Two Terminal Box (1-3/4″ High)
  • Stud Terminals in Standard Three Terminal Box (1-3/4″)
  •  Optional spring Loaded Latch and Trunnion Lock-Up For Large Diameter Bands.
  •  Thermocouple Hole in Gap Shell Overlap With Lock-up
  •  Standard Flange Lock-Up

 Super Insulation Plus:

Super Insulation Plus employs an additional 5/8″ of thermal insulation encased in a separate flexible stainless steel shell.


High performance heater band for processing high temperature engineering resins. “Ultra-Thin” heater bands have the same basic construction as our standard ceramic heaters except they are much thinner and have a high ratio of thermal to electrical insulation. The thin ceramic insulation used results in a lower mass construction, which improves response to control and minimizes temperature lag and overshoot. The backside thermal insulation is highly efficient and results in minimal heat loss and lower sheath temperature.

These are completely flexible radiant heaters.  Heavy clamping pressures are not required regardless of heater size.  No need for hinged, two piece, or expandable designs associated with mineral insulated (MI), mica or other conduction type heaters.
