Desalt DPU-2-36-C SeriesTwo-stage titanium plate type fresh water generator Application Conversion of seawater into freshwater by vacuum distillation for the supply of high quality freshwater for domestic and process utilization. For installation onboard ships, rigs, and onshore remote locations. The DPU-2-36-C is designed for automatic operation with automatic control of freshwater quality. Features • High energy efficiency. • Simple and compact design. • Titanium plate heat exchangers. • Housing in non coated seawater resistant stainless steel. • Combined condenser cooling, ejector water and feed water system. • Freshwater pump and control system. Benefits • High capacity on waste heat available. • High quality freshwater, the low content of dissolved solids (salinity) ensures the supply of pure water which can be used directly as make-up for steam boilers. • Long lifespan, the high grade corrosion resistant materials, i.e. the titanium plates, ensure a long lifespan of the equipment. Alfa Laval fresh water generator type DPU-2-36-C. • Low operation and maintenance costs. Start-and-forget operation, combined with easy access to the interior, reduces man-hours required for operation and maintenance to a minimum. • Simple installation due to compact design, low weight and the possibility to assemble on the spot.

Capacity range The DPU-2-36-C series covers a capacity range from 20 to 75 m3/24h, depending on the heating medium and cooling water temperatures. The capacities shown in fig. 1 are capacities at a cooling water temperature of 32°C. The fresh water generator can be dimensioned to suit any jacket water temperature from 55–90°C at any cooling water temperature required. The quantity of freshwater produced can be altered simply by varying the number of plates in the internal plate heat exchangers. Fig. 1.

Installation The DPU-2-36-C two stage fresh water generator is designed for automatic operation in periodically unmanned engine rooms and other automated operations. The heating medium (see fig. 3) is either engine jacket cooling water or a hot water loop heated, for example, by steam from exhaust gas boiler. The ejector pump is installed separately and has separate suction from the sea. This pump supplies coolant in the form of seawater to the condenser, feedwater for evaporation and jet water for the combined brine/air ejector. The freshwater produced is pumped to the tank by the built-on...
