Collection: Watermaker Membranes

This specialized collection features a comprehensive selection of professional-grade Seawater Reverse Osmosis (SWRO) membranes engineered specifically for marine watermakers and commercial desalination machines. Designed to integrate seamlessly into standard fiberglass (FRP) pressure vessels, these specialized elements provide the exceptional salt rejection required to convert high-salinity seawater into safe, potable drinking water. They are the critical purification component for offshore marine environments, sailing yachts, commercial vessels, and coastal desalination facilities requiring a self-sustaining freshwater supply.

The collection includes industry-leading OEM elements from top global manufacturers such as DuPont FilmTec, Hydranautics (Nitto), Toray, and LG Water Solutions, alongside highly efficient HCTI direct replacement options. Engineered with advanced polyamide thin-film composite (TFC) technology, these membranes are built to withstand the extreme demands of seawater processing. Operating at a standard applied test pressure of 800 PSI, this collection offers a wide range of production capacities—from compact 2.5-inch by 14-inch elements producing 150 gallons per day (GPD) for small recreational boats, up to heavy-duty 8-inch by 40-inch elements capable of yielding 9,000 GPD for large-scale maritime operations.
