An energy saving system to produce fresh water in an efficient and economic way

Cool Steam is a desalination technology based on a multistage vacuum distillation process taking advantage of the surplus energy from industrial processes or nature, that can effectively produce fresh water from (even highly concentrated) salted (brackish or seawater).

The technology works at low temperature and requires a very low overall temperature gradient, which makes it possible to use low grade heat sources.

Both evaporation and condensation occur in the same chamber, which increases efficiency and reduces the need for water pumping or heat losses.
