Multi-effect water distiller adopted the purified water as the feed water, produced WFI (water for injection) by heating industrial steam. Eagle’s LDS series Multi Effect Still adopted the purified water as the feed water, produced WFI by heating industrial steam. The product satisfies the requirement of USP,EP and JP.
Working principle
Qualified feed water will pump into the condenser after increased the pressure by multistage centrifugal pump.
Then pump into each preheaters.
Get into 1st stage evaporator, spray into internal of heater to create film flow, heated by industry steam to create pure steam & water mixture.
Pure steam and water mixture go through Steam Separator.
Non condensate water will move to 2nd stage evaporator. Pure steam will be heating medium for 2nd stage evaporator.
Pure steam from last stage mix with condensate from each stage evaporator ( except from 1st stage), discharge non condensate gas, become WFI after feed water analyzer.
