A line of electrically heated rollers use electric resistance to generate and transfer heat in a uniform, controlled manner. Available in two styles, Thermalon fromAmerican Roller Co.uses a solid-state control system to sense temperature, provide control and power switching, and interface the rollers with existing computerized or PLC machine controls. Temperature uniformity within I1°C across the roller face is maintained through conventional and proprietary heat pipe technology.
