Multi-functional / effect distilled water machine applies to the side of the production of pure steam sterilization, the other side of the production of water for injection production conditions, and the disinfection of water can be run at the same time stand-alone, noninterfering. It is only at home and abroad of the same pace to double production of water and gas injection impact each other pure water and steam production equipment, and without prejudice to the "pure steam" the case of output can change at any time "water for injection" The production, which is the invention of multi-effect distilled water --- Multi-function machine of the original. At the same time, the purchase of more than a pure steam generator (currently the pure steam generator at home and abroad in the same work can not be changed under the pressure of "pure steam" output) and a multi-effect distilled water machine to reduce the fixed asset investment, but also greatly improved the economic performance of equipment.
