45L/h(12 GPH) Compact Modular AC Watermaker: Pure Performance for Coastal & Offshore Cruisers

The PureOcean SE45S Modular Watermaker is our most popular entry-level AC system, specifically engineered for boaters who want the reliability of a professional desalination plant without the massive power requirements. Delivering a steady 45L/h (12 GPH) via a high-performance SW2521 membrane, it is the ideal solution for 25-40ft vessels. By sticking to a 100% manual mechanical design, we’ve eliminated the #1 cause of watermaker failure: sensitive electronics and circuit boards. Whether you are connected to shore power or running a small portable generator, the SE45S ensures you have crystal-clear, WHO-standard drinking water at the turn of a valve.

Ideal for Sailboats, Trawlers, and Weekend Cruisers.

The SE45S is specifically designed for vessels (25-40 ft) where space is tight, but freshwater needs are high. It is a favorite among coastal cruisers and weekend sailors who want to stop relying on dock water and enjoy the freedom of producing their own pure water while at anchor or underway.

① Ultimate Space Utilization: Fit It Anywhere

On a compact cruiser, every locker is precious. The SE45S features a fully unmounted, modular architecture. You can mount the high-pressure pump, the single membrane vessel, and the pre-filters independently to utilize otherwise "dead space" in your bilge or engine room. It’s the ultimate space-saving solution for smaller hulls.

② Bulletproof Reliability (No Electronics, No Headaches)

In the middle of an ocean crossing, you need gear that just works. We’ve stripped away fragile LCD screens and computerized sensors that are prone to corrosion. The SE45S utilizes a rugged manual control panel with marine-grade gauges, ensuring foolproof operation and easy troubleshooting in high-humidity environments.

③ High-Efficiency AC Performance (Low 0.7kW Draw)

Optimized for low energy consumption, the SE45S draws only 0.7kW. This makes it exceptionally "Generator Friendly," allowing it to run effortlessly on small portable generators (like the Honda EU20i) or via your vessel's AC inverter system without overloading your power grid.

④ Global Serviceability & Non-Proprietary Parts

We don't believe in "locked-in" maintenance. The SE45S is built using high-quality, standardized components. This means you can source replacement filters and standard fittings in almost any port worldwide, making it the most DIY-friendly modular watermaker on the market.

⑤ Marine-Grade Construction (Premium SS316)

Zero compromise on quality. The system is centered around a High-Pressure Pump made of genuine marine-grade stainless steel. Combined with an industrial FRP membrane vessel and heavy-duty SS316 fittings, the SE45S is built to withstand a lifetime of saltwater exposure without rusting or leaking.
