In 1939, MECO patented the vapor compression process for the desalination of saltwater. Since then, we’ve refined and improved the technology to deliver high-quality potable drinking water and distilled water in some of the world’s harshest environments. With MECO, you get a completely packaged unit that features the surface preparation and coatings suitable for the marine environment. Plus, the units require minimum field installation. And since MECO has installations worldwide, you have access to a that can respond quickly to emergencies and service maintenance needs.
