An electrically heated industrial oven used to preheat carpet blanks prior to press forming is on its way to an automotive supplier. The preheating oven uses an air-bypass system that prevents heat from escaping the oven chamber when the oven door is open.
Developed by Davron Technologies, Chattanooga, Tenn., the preheating oven was equipped with a dual alternating-rack system. While a carpet blank is heated on one rack, the other rack is simultaneously unloaded and loaded with new product. The air-bypass system captures the heated air while the racks are changing position, increasing energy efficiency.
