Ceramic Band Heaters

In stock

Ceramic band heaters 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.


Advantages of Ceramic Bands

Ceramic Heater Bands

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.


Ceramic Band Heater Details

  1. Stainless steel sheath: Resists rust and high temperatures, and provides firm mechanical support. Easily wraps around barrel due to fluted construction.
  2. Thermal insulation: 1/4 inch of ceramic fiber prevents heat loss, thereby lowering energy costs. 
  3. Ceramic coil supports: Designed for their dielectric and thermoconductive characteristics, the interlocking feature provides flexibility so band wraps easily around barrel. 
  4. Nickel-chrome heating coil: Precision wound, helical construction gives extended service. A heavier weight than found in mica or other conventional heaters.

Ultra Thin Ceramic Band Heaters


Ultra Thin Ceramic Band Heaters

3/8″ thick, , 3/16″ thermal insulation, up to 65 watts/sq. in.

Proheat’s high performance ceramic 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.

The “Ultra-Thin” has averaged 100 deg. F lower sheath temperature when tested against other high temperature heaters at 600 deg. F cylinder temperatures.

The “Ultra-Thin” without thermal insulation and with a perforated sheath is ideally suited for air cooled systems.

“Ultra-Thin” ceramic band heaters are constructed of all high temperature materials. The heater element itself is computer designed for maximum wire size which results in a long service life. Developed primarily for high temperature, high watt density plastic processing machinery, this premium performance heater can be used in many other applications.
