Fast Medium Wave Infrared Heating Lamp is mainly used in the longitudinal stretching process section in BOPET film production.In order to achieve the high light transmittance and the process requirements of raising the temperature to 100℃ within 5s,fast medium wave infrared emitters are best choice as its fall between the short and standard medium-wave. Utilizing the best of both wavelength. Response times as fast as short wave, with a maximum power output of 120 kW/m2 and lengths up to 4 meters.
