Coil Heaters, Coiled Heater Bands and Nozzle Heaters
Coiled heaters are one of Clarians specialist areas where we can supply heaters for the repair of hotrunner systems.
Hot Runner spares; Clarian coil heaters are held in stock and can be coiled to fit into most manufacturers of hotrunner systems. Please contact us for further details
High Performance Tubular Heater
High performance tubular cartridge heaters will work upto 750 degrees c sheath temperture and offer a high watt density heating solution that can be coiled around as opposed to inserted into a tool. Coiled heater are used, where space is at a premium. The coil heaters are available with and without thermocouple and are available either in straight lengh for coiling or as pre coiled types with various different cross sections from round to square and rectangular. These heaters can also be used to heat large platterns and can be shaped to fit into a machined groove.
These heaters are availble from stock with a quick turn around from order to dispatch.
Applications for coiled heaters include plastics industry for the heating of nozzles in hotrunner systems. Coiled heaters are generally applied where space is restricted and are also used in medical and laboratory equipment.
