Fresh Water Generator

ISF-type F.W Generator is designed to produce fresh water from sea water. This generator produces fresh water by evaporating and condensing sea water, and it uses the engine jacket water as the heat source. While a vessel is sailing, it uses main engine to produce fresh water and while a vessel is in port, it uses auxiliary engine.

Sea water is evaporated by the heat which the coolant contains, so it can produce fresh water economically, because it does not need additional heat source. The coolant pass through the heat exchanger to transmit the heat which needed to evaporate sea water, and after transmitting heat, it returns to the engine. When the generator operates, the inner parts will become vacuum, so sea water can easily evaporated in lower temperature and become vapor.

The vapor become water drops by the refrigeration from the cold sea water. When the water drops are collected in waterspout under the condenser, they are sent to the fresh water tank. If the salinity of the produced water exceed the limitation, solenoid valve will go into operation to prevent the inflow of the water with high salinity. In conclusion, the water with high salinity. In conclusion, the produced water's solidity content is less than 10ppm, which is very pure, and also the produced water is soft water, so it can be used in the ship properly

ISF-type Fresh Water Generator consist of main body, a distilling condenser of cooling tubes and a mesh separator in the upper part and a heater tubes in the lower part. Moreover, ejector pump, distillate pump, air ejector, brine ejector, control panel and salinity indicator panel are furnished.

Ilseung Fresh Water Generators are fabricated with SUS316L to prevent corrosion caused by sea water. The material of heating tube bundle and condenser are copper-nickel tubes expended into a tube plate of naval brass at each end. This plant can be delivered after fixing all attachments and its shape is so simple and weights so light that it can be easy to install.

Fresh water produced is extremely pure, containing less than 10ppm of total dissolved solids. Furthermore, it always tastes fresh and clean, and also it is ideal for engine cooling, drinking, cooking, showering and all other personal uses because the produced water is soft water.
