Constructed from the combination of tubular heating elements and high thermal conductivity non-ferrous alloys. The non-ferrous alloys usually are the aluminum and bronze.
Application mainly used in barrel heating with air or liquid cooled built-in for extruders. Platens for presses, packaging and foodservice industries. Pedestals and bake platens for semiconductor processing.
There are no standard sizes of such heater, usually required to be custom made.
