Maltec-H Band Heater | Heating Elements

Band heaters are aluminized steel strip heaters formed to a semicircle and supplied in pairs. A spring at the terminal end keeps the heater halves in contact with the barrel and compensates for thermal expansion. The other end is fastened by a captive chrome plated allen screw for ease of installation. Band heaters are ring-shaped heating devices that clamp around a cylindrical element. Heat transfer from band heaters occurs via the conductive method. Most band heaters clamp around the outer diameter of a cylindrical element and heat the element from the outside. Band heaters are designed to clamp to an exterior or interior cylindrical surface. Band heaters often have higher watt densities allowing fast heat-up and high operating temperatures. They generally include clamp assemblies making installation easy. Band heaters are used for injection molding barrels and nozzles, extrusion and molding presses, pipe heating, heat treating and autoclaves, food industry and other applications.
