45L/h(12 GPH) Compact Modular DC Watermaker: The Essential Choice for Small Cruisers & Solo Sailors

The PureOcean SE45S-DC Modular Watermaker is our most energy-efficient and space-saving solution, specifically designed for small-to-medium vessels where power management and storage are critical. Delivering a reliable 45L/h (12 GPH) via a single high-performance SW2521 membrane, this system is the perfect match for solo sailors, couples, and weekend explorers. By removing complex electronic circuit boards, we’ve created a "bulletproof" manual system that thrives in harsh, high-vibration marine environments. Whether you’re island hopping or preparing for an emergency coastal crossing, the SE45S-DC provides pure, WHO-standard drinking water with zero unnecessary gimmicks.

The Ultimate Solution for Compact Vessels & Minimalist Cruisers.

The SE45S-DC is the ideal choice for sailboats, pocket cruisers, and fishing boats (25-35 ft) where a traditional, heavy AC watermaker is not an option. Its modular nature allows for a clean, customized DIY installation in awkward spaces, providing freshwater independence for those who prefer to explore off-the-beaten-path.

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

On a smaller boat, every inch counts. The SE45S-DC features a completely unmounted, modular layout. Unlike bulky framed units, you can independently mount the compact high-pressure pump, the single membrane vessel, and the pre-filters. It easily tucks into narrow bilges, under bunks, or inside small lockers, making it the "space-saving champion" of our lineup.

② Bulletproof Reliability (No Electronic Failure)

Designed for the "Simplicity is Safety" philosophy. We’ve eliminated fragile LCD screens and computerized sensors that often fail in salt-spray environments. The rugged, manual control panel gives you direct mechanical command, ensuring maximum dependability when you are miles from the nearest technician.

③ Optimized DC Performance (0.65kW Low Draw)

Specifically engineered for 12V/24V/48V DC power systems. With a highly efficient 0.65kW motor, the SE45S-DC is perfectly suited for boats relying on solar panels and battery banks. It delivers a consistent 12 GPH output without putting an excessive strain on your vessel's electrical grid.

④ Global Serviceability & DIY Friendly

We believe in empowering the owner. The system uses high-quality, standardized components (non-proprietary), meaning you can perform routine maintenance yourself and find replacement filters or parts in almost any port worldwide.

⑤ Marine-Grade Construction (SS316 Stainless Steel)

Built to survive the ocean. The core of the system features a High-Pressure Pump crafted from premium marine-grade stainless steel. Combined with an industrial-grade FRP membrane vessel and heavy-duty SS316 high-pressure fittings, the SE45S-DC offers ultimate defense against saltwater corrosion for a lifetime of service.
