The Backer Marathon Starflex band heater is an extruded aluminum segmented band employing rugged refractory insulated tubular heating elements. The low expansion clamping band provides snug barrel fit and and assures excellent heat transfer through the entire operating temperature range up to maximum heater temperatures of 600°F. This band heater enjoys wide acceptance because of extremely long and reliable life characteristics. Operators of plastic extruders and injection molders experience minimum down-time with the Starflex band. It is also one of the most efficient band heaters available.
Some applications require both heating and cooling. With the advent of exothermic materials and heat generated by screw rotation, the proven Backer Marathon Starflex band heater was adapted to provide both heating and cooling functions. Cooling tubes are placed in proximity to the heating elements to produce the Backer Marathon Starflex Heat/Cool band. Due to its low mass, it can be cooled relatively quickly.
We also manufacture cool only bands in a configuration similar to the Heat/Cool band. Cool only bands are manufactured with stainless steel tubes to meet a wider range of temperatures.
