CERAMIC BAND HEATERS |
 |
To meet the demands for all type of plastic processing machinery. These heaters are capable of very efficient heat transfer by radiation, conduction and convention. 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 from 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 surface 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 simply wiring.
