Starflex Heaters

General Description and Construction
The Glenn 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 assures excellent heat transfer through the entire operating temperature range up to maximum heater temperatures of 600 degree F. This band enjoys wide acceptance because of its extremely long and reliable life characteristecs. 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 Glenn 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 Glenn Starflex Heat/Cool Band. Due to its low mass, it can be cooled relatively quickly. Glenn also manufactures Cool Only Bands in a configuration similar to the Heat/Cool Band. It should be noted copper cooling tubes may be used for operating temperatures up to 350 degree F, but temperatures above 350 degree F require the use of our stainless steel cooling tubes.

Installation of these bands is easily performed by opening the band, placing it around the cylinder and tightening a single screw. Large diameter bands are furnished with multiple clamping assemblies and multiple segments for grasping the surface.

Typical Applications
Glenn Starflex Band Heaters are designed for use in barrel heating of extrusion and injection molding machinery, blown film dies, and other cylindrical surfaces. Their configuration can be for full 360 degree coverage or any other degree of partial wrap. Internal bands and Type TNH Nozzle heaters are also available.
