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 heating plays main role during glass heating. After being heated in jet convection chamber, the hot air inside heating furnace is blown onto glass surfaces and then goes back to hot a
