These heaters are constructed using Watlow's exclusive mineral insulation, which has high thermal conductivity. The band and strip emitters are also constructed of rugged stainless steel sheath with a high emissivity coating. These heaters can operate at temperatures to 1300°F (700°C), and 30 W/in2 (4.7 W/cm2)
