Heat Exchanger Solution Partner Fresh Water Generator Our company endeavor ceaselessly DongHwa Entec Fresh Water Generators are the equipment that convert sea water or exhausted dirty water to pure water for drinking, boiler make-up, domestic use on ship and small power station. At that time, sea water is evaporated at about 45°C -50 € as it passed the inside of heater under the high vacuum condition and the separated pure vapor is converted to fresh water on condenser. Plate Type Tubular Type DongHwa Eniec Heat Exchanger Solutions

Fresh Water Generator Plate Type 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 water...

Plate Heat Exchangers Working Principle Fluid distribution- transfer area Leakage vent—[ Gasket is attached to the heat plate which forms flow channel and acts seal up the fluid not to leak to the outside. The number of the heat plate is determined according to the amount of fluid, physical properties of fluid, the pressure drop and thermal condition. The covers prevent the plates bended from the difference of pressure. In the assembly of plate, the surface with gasket is directed to the fixed cover and each plate is hanged in opposite direction alternately. And two fluids cannot be mixed...

Characteristics Wide contact area The strength of the plate is excellent, compared with other companies' products with the point contact type, as the metal contact point has the surface contact feature when the plates are assembled. And the durability and corrosion resistance are greatly improved by minimizing deformation and stress concentration. Besides, the section of the gasket is designed and manufactured to have a pressure-resistant structure that enables the minimum contact area with the fluid, and thus to withstand a high pressure. Dead Zone Clip Gasket Others The gasket can be...
