DOUBLE EFFECT TYPE WATER MAKER DF 35/60/2 Fresh Water Generator Introduction The DongHwa Double Effect Type Water Maker is the equipment that convert seawater or exhausted dirty water to pure water for drinking, boiler makeup, domestic use on ship and small power station. At that time, seawater is evaporated at about 70°C, 45°C respectly as the one passed the inside of heater under the high vacuum condition and the separated pure vapor is converted to freshwater on condenser.(stage2) The other one is going to the heating medium of heater and then converted to freshwater.(stage 1) Operating...

Fresh Water Generator Working Principle Tubular Type The main engine jacket cooling water circulates the outside of the vertical tube in heating section and the sea water to be distilled is sent to the bottom cover of this section. Then some of the sea water is converted into vapour when it goes up through the heated tubes. The vapour, through the demisters, is condensed on the outer surface of the tubes of the distilling condenser and the resultant distillate is led to the suction of the distillate pump. In the meantime the non-condensable gases and brine are extracted and discharged to...

Fresh Water Generator Working Principle The DongHwa Entec DF Series Fresh Water Generator utilizes the heat from diesel engine jacket cooling water to produce pure drinkable water by evaporating sea water under high vacuum enabling the feed water to evaporate at temperatures below 48°C. Steam can also be used as the heat source instead of the hot jacket water. The DongHwa Entec DF Series Fresh Water Generator is based on 2 titanium plate heat exchangers acting as an evaporator and a condenser respectively. The evaporation chamber is kept under vacuum by a water ejector driven by the sea...
