The flow control separation of cleaning and protective gases means that once the furnace is cleaned by the atmosphere, the protective gas can be used at a lower flow rate. The switching between cleaning and protective gases can be done manually or by adding an automatic programming control system accessory. The oxygen content * can decrease to 50ppm.
