80L/h(21 GPH) Compact Modular AC Watermaker: The Balanced Choice for Coastal & Blue Water Cruising

The PureOcean SE80S is a highly versatile modular watermaker designed for sailors who need a significant freshwater output but have limited linear space for long membrane housings. Delivering a consistent 80L/h (21 GPH) using a high-efficiency dual SW2521 membrane configuration, it provides the perfect balance of performance and footprint. Like all SE series units, it features a 100% manual mechanical design, stripping away fragile electronics to ensure absolute reliability in remote tropical environments. Whether you are prepping for a week-long island hop or a month-long offshore passage, the SE80S delivers pure drinking water with zero technical complexity.

Perfect for Mid-Sized Sailboats, Catamarans, and Trawlers (35-48 ft).

The SE80S is the "sweet spot" for small crews and families. Its 21 GPH output is enough to support multiple daily showers, dishwashing, and all drinking needs, while its modular, dual-membrane design provides the flexibility required for custom installations in tight bilges or engine rooms.

① Optimized Form Factor: Dual-Membrane Versatility

The SE80S is unique because it utilizes two compact SW2521 membranes instead of one long vessel. This allows for a much shorter installation footprint, making it the ideal "fit-anywhere" solution for mid-sized sailboats and powerboats where locker length is restricted.

② Bulletproof Reliability: No Electronic Failure Points

Marine environments are brutal on circuit boards. The SE80S eliminates this risk by using a rugged manual control panel and high-quality analog gauges. This "Simplicity is Safety" approach ensures you can always produce water, even if your vessel’s sensitive electronics are affected by salt spray or humidity.

③ High-Efficiency AC Power (0.8kW Draw)

With a modest 0.8kW power consumption, the SE80S is exceptionally "Generator Friendly." It runs effortlessly on small portable generators (like the Honda EU20i) or your vessel's AC inverter system, allowing you to fill your tanks quickly without a massive energy penalty.

④ Global Serviceability & DIY Maintenance

Engineered for the global cruiser. We use high-quality, standardized, non-proprietary components throughout the system. This means you are never "locked-in" to expensive brand-name filters—replacement parts and standard 10-inch pre-filters can be sourced in almost any port worldwide.

⑤ Marine-Grade Construction: Premium SS316 & Stainless Pump

Constructed for a lifetime of service. The SE140 features a High-Pressure Pump crafted from premium marine-grade stainless steel. Combined with industrial-grade FRP membrane vessels and heavy-duty SS316 high-pressure fittings, this system offers the ultimate defense against the corrosive marine environment.
