Fresh Water Generator - Tubular Type

ISF-type Fresh Water Generator is designed to produce fresh water from sea water. This fresh water generator uses the engine coolant as heat source and produces fresh water by evaporating and condensing sea water.

To evaporate sea water, it only uses the heat from coolant so, while a vessel is sailing, it uses main engine, and while a vessel is in port it uses auxiliary engine to produce fresh water. After all, ISF-Type fresh water generator can produce fresh water economically without any additional heat source(The coolant pass thorough the heat exchanger to transmit heat for evaporating sea water.

At last, this heat goes back in to the engine). While the generator is running, the inner parts will be vacuum, so the boiling point of sea water will be dropped. The vapor become water drops by 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 operate to prevent the inflow of the water with high salinity. In conclusion, the produced water's solidity(salinity) is less than 10ppm, which is very pure, and also the produced water is soft water which can be used in many purposes.
