Cast In Heaters by Hampton Controls

Cast-in liquid cooled barrel heaters are the most common cast -in heater design used on plastics extrusion barrels.

Liquid Cooled and Air Cooled Cast In Barrel Heaters

The liquid cooling tubes run symmetrical to the heater element, which provides a uniform cooling pattern across the body of the casting. This cooling function dissipates heat rapidly from the cast-in barrel.

To maintain lower watt densities important for good heater life, the largest possible diameter steel sheath tubular heater is used. Cooling tube extensions can be cut to your specified length.

Many options available:

Liquid or Air Cooled
Aluminum, Bronze, Brass
And other custom types

Air Cooled Finned Cast In Barrel Heaters

Air Cooled finned Barrel Heater designs provide effective heating and cooling for plastics extrusion barrels as well. For smaller extruders or applications requiring rapid cooling, this design can be manufactured to a low profile thickness. The standard height of 1" is common with Air Cooled Finned Barrel Heaters.

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.
