Donghwa Entec’s fresh-water generator is a device to produce fresh water by using seawater and comes in two models of low pressure evaporating type and reverse osmosis type.
Currently, most of the merchant ships in the world are adopting the low- pressure evaporating type to produce fresh water by using steam or jacket water, which is a waste heat source from engine and F.W.G is largely divided into shell & tube type and plate type.
S.W. is vaporized under vacuum by extra heat source and salinity is percolated from the vaporized S.W. and fresh water is gained by condensing them. And it is necessary to maintain salinity not to exceed 0 ~ 10ppm. F.W.G. consists of vaporizer, condenser, demister, salinometer, distillate pump, ejector and steam injector.
The fresh water generator from the company is exported to Japan, China, Singapore, and Brazil. Recently, some European countries are emerging as new potential export destinations in spite of the regions’ economic instability.
