Application The APV Water Desalination Unit type H-CE is a fresh water generator fordesalination 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 andcondenser, separated by stainless steel demister. The H-CE unit is available in four sizes with capacities ranging from 20m3/24h to 33m3/24h.

Working principle The vessel with evaporator and condenseris evacuated to -0,93 bar by the seawater-driven ejector. At this pressure, the seawater to be distilled enters the evaporator where it evaporates at approx. 44°C - 49°C when passing the plates heatedby the heating medium - typically hot water (engine jacket water) at 75°C - 90°C. The steam leaves the evaporator through the open side of the plate pack and passes through a demister, where anycarryover drops are separated 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. Thefreshwater is pumped to the freshwater tank, passing a sensor connected to the salinometer. If the salinity is higher than the pre-set reference value the solenoid valve is activated and the flow is directedback for re-production.

Products features • Heat exchangers with specially designed Titanium plates for effective steam passage and high efficiency • Condenser cooling combined with ejector waterand feed water system and complete piping • Compact and space saving design

Standard equipment The APV H-CE Water Desalination Unit includes Titanium plate heat exchangers for evaporator andcondenser, vessel, seawater ejector, freshwater pump, freshwater meter, frame, control panel with motor starters and salinometer, and dosing unit for antiscaling.

Benefits • High fresh water quality:...
