Ceramic Band Heater

S- HEATWELL  Ceramic Band Heaters were developed to meet industrial requirements for high temperature long lasting heaters. They are ideally suited to comply with today's new resins, which calls for ever-increasing process temperatures.

An additional advantage of the Ceramic Band Heaters is that they transfer heat through conduction and radiation. This makes their tightness on barrels less critical; thus they are less prone to thermal expansion problems.

Theoretically, there are no restrictions on the diameter that ceramic band heaters can attain; however, because these heaters utilize ceramic tiles that are available only in specific lengths, the width of these heaters falls within a certain incremental range of sizes.

                              Construction

                                                                            Ceramic band heaters are designed with spirally wound inner resistance coils evenly threaded through                                                                                    interlocking insulated ceramic “tiles”. The ceramic core, or “mat” of tiles is housed beneath a stainless steel                                                                              sheet with serrated edges. This combined assembly of the Ceramic Band Heater offers a flexible heating                                                                                  system that yields efficient transmission of conduction and radiated heat. The heat of the Ceramic Band                                                                                  originates from the inner coils that conduct heat at maximum temperatures. The heated coils evenly                                                                                        deliver heat through the ceramic tiles which radiate energy to the barrel. We offer a variety of Ceramic                                                                                      Band styles with customized configurations.

  • Built in insulation minimizes unwanted change in temperature along the barrel

  • Heat transfers through radiation, conduction, and convection,

  • so a perfect fit is not required compared to other band heaters

  • Extrusion Line

ADVANTAGES

  • Heat transfers are not affected by irregular surfaces or a loose fit

  • he number of bands used can be reduced with simplified wiring

  • The flexible design allows easy install and removal

  • Because they operate at higher watt densities, they can be

  • used in wider increments

  • The heater is safer with the cooler external surface – over ot

  • her band heaters

APPLICATION

  • Injection Molding Machine

  • Blow Molding Machine
