.5" x 21" 1,000 PSI FRP Pressure Vessel Membrane Housing (SW30-2521 Compatible)
Engineered specifically to house standard 2.5-inch by 21-inch commercial seawater reverse osmosis elements—making it the perfect, heavy-duty fit for the DuPont FilmTec SW30-2521 membrane—this premium-grade pressure vessel is built for high-pressure seawater reverse osmosis (SWRO), marine watermakers, and industrial desalination applications. Designed to securely accommodate your SW30-2521 element, this robust housing delivers the structural integrity required to operate safely under the extreme continuous-duty pressures necessary to purify seawater.
Constructed utilizing an advanced filament winding process, the vessel's shell is composed of continuous fiberglass impregnated with a heated epoxy resin system. This exceptional Fiberglass Reinforced Plastic (FRP) construction allows the housing to safely withstand a maximum operating pressure of 1,000 PSI (69 bar), completely fulfilling the rigorous high-pressure operating requirements of the SW30-2521 element to overcome the high osmotic pressure of seawater. The exterior is finished with a protective white coating to resist harsh, corrosive marine environments, salt spray, and prolonged UV exposure on decks or offshore platforms.
To ensure a secure, leak-proof seal during intense high-pressure operation, this housing is equipped with heavy-duty stainless steel end caps featuring a highly reliable double O-ring design. The housing utilizes standard 1/4-inch NPT ports for straightforward plumbing integration with your marine watermaker's high-pressure pumps and manifolds. For a complete and hassle-free installation of your SW30-2521 element, the vessel includes the necessary mounting straps and rubber saddles, providing facility operators and marine technicians with a reliable, ready-to-mount containment solution.
