Oceans of fresh water, drop by drop
Cool Steam
Cool Steam was born with the spirit of taking advantage of the resources that the environment offers us to obtain drinking water from seawater with minimal impact, emulating the natural processes of the water cycle.
Cool Steam is a desalination technology based on the multistage vacuum distillation of water from diverse origins (sea, brackish, polluted, industrial, etc.) at low pressure and temperature, taking advantage of the surplus energy from industrial processes or nature.

2Cool Steam
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.
FWN and CIMNE, together to bring fresh water to the world
Water is present all over the world; let's make it fresh, safely clean and affordable through Cool Steam, the innovative and sustainable vacuum distillation process developed by FWN & CIMNE.
