The product of decades of research and development, the Alfa Laval freshwater generator concept offers effective solutions to all the problems commonly associated with traditional designs:

  • Low scaling rate and high reliability mean very little maintenance
  • High-grade materials make coating repairs a thing of the past
  • Titanium plates in the heat exchangers and extensive use of non-ferrous materials prevent corrosion of vital parts
  • Compact, lightweight design fits easily into engine rooms where space is at a premium

Alfa Laval freshwater generators utilize the waste heat generated by the main engine and/or the auxiliary engine as a heat source for the distillation process.

The range of Alfa Laval Plate Type Freshwater Generators covers capacities from 0.5 to 115 m3 fresh water per 24 hours with a guaranteed maximum salinity of 2.0 ppm.
