80L/h(21 GPH) Compact Modular Watermaker: Ideal for Sailing & Short Trips

The PureOcean SE80 Modular Watermaker is built for the practical sailor who values bulletproof reliability over complex electronics. Engineered with a capacity of 80L/h and powered by a single SW2540 membrane, this system is the perfect match for medium-sized and compact boats. We stripped away fragile computerized screens and sensors to create a system that is 100% mechanically driven, ensuring it remains easy to install and maintain. Whether you are purifying ocean water in the Caribbean or brackish water in a remote estuary, the SE80 delivers consistent, crystal-clear drinking water. No gimmicks, no proprietary traps—just freshwater freedom miles from shore.

Perfect for Compact Cruisers and DIY Installs.

Space is your most valuable asset on board. The SE Series features a true unmounted, modular layout. You can separate the high-pressure pump, the RO membrane vessel, and the pre-filters to fit into tight bilges, under settees, or in crowded engine lockers. It is the ideal choice for sailboats, catamarans, and powerboats (30-45 ft) where a traditional framed watermaker simply won't fit.

① True Modular Freedom: Fit It Where Others Can't

Space is your most valuable asset on a boat. The SE80S-DC features a completely unmounted, modular layout. Unlike traditional framed units, you can separate the high-pressure pump, membrane vessels, and pre-filters to fit into tight bilges, under settees, or in crowded engine lockers.

② Bulletproof Reliability (No Electronic Failure)

Designed for serious ocean voyages where "simplicity is safety." We’ve eliminated fragile electronic display screens that are prone to salt-spray damage. The rugged manual control panel ensures foolproof operation and maximum dependability in the harshest environments.

③ High-Efficiency DC Performance

Optimized for DC power systems, the SE80S-DC delivers a consistent output of 70L/h – 80L/h (approx. 18-21 GPH). It is the perfect balance of low power draw and high freshwater production for mid-sized cruisers.

④ Global Serviceability & DIY Friendly

Built with the practical sailor in mind. The system is easy to install and even easier to maintain. We use high-quality, standardized components, meaning you can find replacement parts in almost any port worldwide.

⑤ Marine-Grade Construction

Every component is specifically engineered for the harsh marine environment. The system features ahigh-pressure pump crafted from premium marine-grade stainless steel, alongside industrial RO membranes andheavy-duty SS316 fittings. This ensures ultimate corrosion resistance and a superior service life even in constant saltwater exposure.
