Fresh Water Generator - Plate Type

The IL Seung Plate Type Fresh Water Generator (ISF-P) utilizes the heat from diesel engine coolant to evaporate sea water. Also, evaporation process occurs under high pressure to lower the boiling point under 48 degree celsius(118 degree Fahrenheit). Steam from evaporation can be used as heat source instead of hot coolant.

ISF-P is based on two titanium plate heat exchangers acting as an evaporator and a condenser. The evaporation chamber maintains the vacuum condition by a ejector. Part of sea water from evaporation chamber is used as feedwater for the evaporator. The feedwater evaporates when entering the evaporating chamber due to the vacuum condition.

Water particles and droplets are partly removed from water vapor by the built-in demister and the deflector mounted on the top evaporator. Separated droplets are brine, extracted at sump by an ejector pump. The desalted vapor passing through the demister is condensed by the plate condenser with incoming cold sea water.

The pure distilled water is taken out by discharge pump. The pure water from condenser is controlled by the pre-installed salinometer to not exceed salinity level of 1-10ppm. If the salinity exceeded the specified level, solenoid valve in discharge line will automatically return the faulty distilled water to the feed line.
