General
Based on the general design scheme, the Fresh Water Generator which mainly consists of evaporating and condensing chambers, ejector equipped for vacuum, as well as relevant accessories for the system.
Furthermore the whole control system is to be designed as maker standard in according to our design purpose.Subject salinity meter is exclusively composed by maker, the design scheme concludes with temperature compensation.
The system designed under rough sea condition. That is for 32 ℃ sea water and 75 ℃cylinder jacket cooling water. Under such circumstance, the unit can reach distillate production capacity of 5 t/d. Each unit consists of a condenser and an evaporator installed in a same chamber.
Characteristics
The plant is a packaged unit, which is mounted on a base frame. All components and accessories. such as fresh water pump, interconnecting pipe-work as well as inner cable are connected prior to delivery.
The sea water pump independently supplied for on-site installation on board, which is to bepositioned under the light ballast line.
