The Ceramic Band Heater by Subhot Enterprises Pvt. Ltd. is designed for hightemperature and energy-efficient heating of cylindrical surfaces such as barrels, nozzles, and extrusion machines. Unlike mica heaters, ceramic band heaters utilize ceramic insulation (steatite), which not only conducts heat by conduction but also radiates it effectively, providing a higher degree of thermal efficiency.
Built with a precision-wound Nichrome resistance coil embedded in ceramic halves, enclosed in a stainless steel or aluminum-clad sheath, these heaters ensure uniform heat distribution, reduced energy consumption, and a longer service life. They are widely used in plastics, packaging, chemical, and semiconductor industries, where stable high-temperature heating is essential.
