Water Systems

C’treat has been manufacturing and supporting high quality Reverse Osmosis Watermakers and Packaged Water Systems for the Offshore Oil & Gas industry for over 30 years. With hundreds of systems installed around the world, we are a leading provider of fresh water for offshore applications.

Our Desalination Systems use proven technology and components that have been demonstrated in the field for decades. Our equipment is simple to maintain offshore and operates reliably with little attention. When measured by the cost of water produced (pennies per gallon), C’treat builds the most economical desalination systems available.

Together with its long-term Malaysian partners, South Seas Offshore (of OLIO Group) and C'Treat have captured a substantial market share in Malaysia with technical support for the region.
