Product DescriptionWFI (Water for Injection) Preparation and Storage SystemWorking principle 1: Working principle 2: WEMAC's LDS series Multi-column Water Distiller is a kind of equipment to produce water for injection by using purified water as feed water and heating with industrial steam. The water for injection produced by LDS Multi-column Water Distiller meets the specification requirements of Chinese Pharmacopoeia (CP2020), U.S. Pharmacopoeia (USP43) and European Pharmacopoeia (EP10) for water for injection.Qualified feed water is pressurized by multi-stage pump into the Condenser, and then sequentially into each Preheater (fed water in the Condenser is heated by the secondary steam, distilled water, and then into each Preheater after the condensed water is heated by the secondary steam, and in the first Preheater is heated by the condensed water of the industrial steam), and then into the first Evaporator through the feed water distributor is sprayed on the inner wall of the heating tube, so that the feed water in the wall of the tube becomes a film flow, and is heated by the industrial steam. Heating vaporization.Produced entrained water droplets of the secondary steam, from the lower end of the evaporation chamber into the vapor separation device, was separated from the pure steam into the next Evaporator as a heating steam, not evaporated feed water into the next Evaporator, repeat the above process. The pure steam produced by the final Evaporator into the Condenser with the condensed water from the condensed water in addition to the first Evaporator of the convergence of cooling, by excluding non-condensable gases (depending on the model, the Evaporator can also be equipped with such non-condensable gases on the continuous discharge device), to become the water for injection. The outlet is usually tested online for conductivity, and qualified distilled water is exported as water for injection, while unqualified distilled water will be discharged.
