Ceramic band heaters are a type of industrial electric heater designed to provide efficient and uniform heat to cylindrical surfaces, such as pipes, barrels, or nozzles. These heaters consist of a ceramic insulating jacket that encases a heating element. The ceramic material used in the construction of these heaters provides excellent thermal insulation, allowing for high-temperature applications. Ceramic band heaters are commonly used in the plastics processing industry, extrusion processes, and other industrial applications.
