Plate Evaporator · Freshwater Generators
Wärtsilä SERCK Tipo 500 is a plate evaporator. It is installed in the engine room and connected to seawater, heating medium, vacuum or ejector, distillate and freshwater systems. Its purpose is to produce freshwater from seawater by evaporating water at reduced pressure and condensing the vapor as distillate. A plate or other evaporator section, condenser, ejector or vacuum arrangement, pumps and salinity monitoring form the plant. The exact model designation and the listed capacity distinguish production capability and heating-surface arrangement from neighboring generators; refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Trend freshwater production, salinity, vacuum, temperatures and seawater flow against established normal operation. Inspect and clean evaporator and condenser surfaces using approved methods and maintain seawater strainers. Check ejectors, pumps, valves and vacuum leaks when production falls. Verify the salinity cell and automatic diversion after maintenance. Prevent excessive scaling by following the vessel's operating and treatment procedure. Refer to the manufacturer documentation for the exact figure for vacuum, temperature, cleaning and salinity limits.
Keep plate gaskets or seals, salinity-cell service parts, ejector nozzles, pump seals, valve kits and manufacturer-recommended heat-transfer components. Strategic spare plates or a replacement salinity sensor may be appropriate for critical vessels. Confirm materials and parts from exact model documentation.
