High Vacuum Aluminum Brazing Furnace
1.Usage & Features
The RVB-1111L-AL high vacuum Aluminum soldering furnace is horizontal type with front door & back door design. High pumping speed oil diffusion pump groups, full metal shield insulation layers, fast pumping speed & inner clean.
It’s used in aluminum base materials vacuum brazing, finished works keep bright surface & non-oxidation.
The control system was controlled by PLC, Manual or Auto undisturbed switches and alarm function for abnormal condition, high automation and easy operation.
