AirStreamTM ——Radiation heating plays main role during glass heating, while compressed air is injected into heating furnace, in which it brings certain amount of heat onto glass top surfaces and is helpful for even heating online low-E glass, etc. SuperAirTM ——Radiation heating plays main role during glass heating, while larger volume of compressed air is blown into heating furnace by intelligent pipe convection system. Therefore, both online and offline low-e glass can be evenly heated. JetConvectionTM—— Convection heationg plays main role during glass heationg. After being heated in jet convection chamber, the hot air inside heating furnace is blown onto glass surfaces and then goes back to hot air blowers for contiuous circulation, which not only ensure even heating, low production costs, but enhance the quality of the end products as well. LD-AT series Combined Flat tempered glass machine,LD-AT series Combined Flat  tempered glass machine,has two combined heating sections, in which JetConvection heating and AirStream heating technologies are applied for optimum heating effect according to different features of glass sheets; its quenching and cooling section consists of one chiller or more chillers according to quality requirements of end products.
