Seawater Desalination Watermakers


Seawater Desalination Reverse Osmosis System
With over 20 years of experience, Ampac USA has been designing and manufacturing advanced Seawater Desalination Systems Watermakers for the on-shore and off-shore industries.

Onshore Fresh SWRO Watermakers, designed for land use, can be fed directly from the sea or any beach well, and will convert seawater or salty brackish water to pure fresh drinking water.  These LandPro ™ systems are perfect for locations with no fresh or municipal water supplies such as remote areas, or smaller atolls and islands having no potable water sources.  

SeaPro ™ marine off-shore watermakers convert seawater fed directly from the sea into drinking quality water and suits most boats, yachts, oceangoing industrial vessels and military ships.
