Working principle The vessel with evaporator and con-denser is evacuated to -0,93 bar by the seawater-driven ejector. At this pressure, the seawater to be distilled enters the evaporator where it evapo- rates at approx. 44C - 49аC when passing the plates heated by the heating medium - typically hot water (engine jacket water) at 75C - 90аC. The steam leaves the evaporator through the open side of the plate pack and passes through a demister, where any carry-over drops are sepa- rated for re-circulation, and then enters the condenser positioned above. The clean vacuum steam is condensed into freshwater by circulating cold water on the other side. ՕՕ > Additional equipment required Standard equipment Application Benefits The freshwater is pumped to the fresh-water tank, passing a sensor connect- ed to the salinometer. If the salinity is higher than the pre-set reference value the solenoid valve is activated and the flow is directed back for re-production. Seawater pump The APV H-CE Water Desalination Unit includes Titanium plate heat exchangers for evaporator and con- denser, vessel, seawater ejector, fresh- water pump, freshwater meter, frame, control panel with motor starters and salinometer, and dosing unit for anti- scaling. The APV Water Desalination Unit type H-CE is a fresh water generator for desalination of seawater for production of potable and fresh utility water; used for installation on board ships and rigs. The water desalination unit is a single stage, plate type evaporator and con- denser, separated by stainless steel demister. The H-CE unit is available in four sizes with capacities ranging from 20m High fresh water quality: Automatic feed-water dosing valve secures optimised freshwater production and low salinity Low operation costs: Reduced heat consumption due to pre-heating of feed-water and full access for clean- ing and inspection reduce operation and maintenance costs Reduced service intervals: Use of corrosive resistant Titanium plates. Pre-installed adjustable chemical dosing unit reduces fouling Reduced installation costs. Fully equipped control box for easy instal- lation and operation and complete piping.
