Cast Barrel Heater
Cast Barrel Heater
Durex Industries manufactures cast-in heaters for plastics extrusion equipment. These heaters, which also feature liquid or air cooling options, are primarily used as a high performance heating and cooling source for plastics extruder barrels. Constructed of aluminum or bronze alloy, the cast-in heaters utilize a rugged tubular heating element, uniformed for heat distributed evenly throughout the casting. The inner diameter is precision machined for an exact fit to the exterior barrel. Various termination options are available for any extrusion application, including stud terminals with ceramic insulators, stainless steel armor cable or explosion-proof housings. Cooling tube terminations include compression fittings and cast-in threaded fittings for quick insulation. Shroud assemblies with blowers are available for air-cooled fin designs. Durex also manufactures cast-in heaters for blowmolding, insert molding and die heating applications.
