Hi-Watt sells Tempco and Durex Cast-In Heaters: Cast-in heaters of aluminum and bronze for various heating applications in industries, such as Semiconductor and Plastics Processing, Packaging Machinery, Foodservice, Paper Processing, Hot Melt Adhesives, Medical Equipment, Heat Transfer Presses and Textile Manufacturing. Finned Cast-In Band Heaters are manufactured in aluminum alloys because this material provides very good thermal conductive properties. For applications requiring higher operating temperatures and/or higher watt densities, bronze or brass alloys can be used. Finned Cast-In Band Heaters can be designed to meet the mechanical and physical constraints of existing extruder shroud systems. Hiwatt also can order custom cast in heaters to fit any need you many require. Give our sales team a call for a quote.
