Barrel Heaters

Our range of barrel heaters includes custom-designed mica and ceramic band heaters, heater/cooler assemblies, and cast aluminium or bronze options. These heaters provide efficient, uniform heating for barrels, cylinders, extrusion tooling, and polymer processing equipment, tailored to meet your specific temperature control needs.

Features include segmented bands for improved fit, hinged sections for easy installation, heat reflector shields to enhance thermal efficiency, and integrated thermocouple fittings for precise temperature monitoring. Additionally, heaters can be customised withs holes, cut-outs, and threaded bridges to accommodate unique machinery requirements.

Available in single- and three-phase voltages, our heaters offer flexible termination choices including terminal boxes, 2-pin or 3-pin sockets, and various cable types. We also supply heater banks – connecting multiple bands under a single terminal box to simplify wiring and improve heating consistency.

Our heater/cooler assemblies combine powerful heating elements with integrated cooling fans, housed in precision-engineered casings for reliable temperature regulation in demanding environments. Manufactured in the UK with fast lead times and expert support, our barrel heaters deliver dependable, long-lasting performance across a variety of plastic processing applications.
