Stainless Steel Liquid Tube Cooled Cast In Barrel Heaters for Extrusion Processing

Description

Finned air-cooled cast-in designs provide effective heating and cooling for plastics extrusion barrels. The fin pattern can be supplied as a standard height of 1” or manufactured to a low profile thickness for small extruders or applications requiring rapid cooling. This pattern is designed to allow the optimal airflow around the casting for maximum cooling rates. Typically the forced air for the cooling function is driven by a shroud and blower system that is an integral part of the extruder, however these cast- in heaters can be utilized with an individual shroud and blower assembly for increased cooling control of the individual heater zones. All Durex cast-in barrel heater designs are available with mounting options of stainless steel locking straps or bolt-on clamping construction. Various electrical termination options are available for the air cooled cast-in heater depending on the application and environmental requirements.
