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.
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
DPU - Two-stage titanium plate type fresh water generator
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.
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.
How it works
DPU, Titanium plate type fresh water generator
The DPU-36-C series covers a capacity range from 10 to 55 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 exchanger.
