JetConvectionTM ---Convection heating plays a 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 air blowers for continuous circulation, which not only ensure even heating, low production costs, but enhance the quality of the end products as well. LD-BE JetConvection double bent bi-directional ttempering furnace adopts JetConvection heating technology, this furnace has two bending quenching sections that lie on both sides of the heating furnace. By loading the glass in different direction, the furnace can temper single curvature and double curvature bent glass for automobile. Glass can be tempered includes: on-line and off-line Low-E(E=0.02) glass, extra white glass, silk-printed glass, pattern glass, tinted glass, clear glass, etc.
