Overview

Vapor Compression for Desalination

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. And since MECO has installations worldwide, you have access to a global service network that can respond quickly to emergencies and service maintenance needs.
