PureOcean Marine Pro300 Modular Watermaker (110V/220V AC | 80 GPH / 300 L/h) · Embedded / AC 220 V / 50 Hz

The PureOcean Pro300 is the highest-output model in our Pro Series, specifically designed for vessels with substantial freshwater requirements. Delivering a reliable 300L/h (80 GPH) via a quad SW2540 membrane array, it provides an efficient solution for filling large storage tanks during offshore voyages. True to the Pro Series philosophy, the Pro300 features our signature stainless-steel dashboard for centralized analog control. By utilizing a high-performance motor and a purely mechanical interface, it ensures high-volume production and long-term dependability without the complexity of sensitive electronics.

Highlights

① Flagship High-Volume Production (80 GPH)
The Pro300 delivers 80 gallons of pure water per hour. This massive flow rate is designed to support large crews, multiple guest heads, high-capacity laundry machines, and full-sized dishwashers simultaneously. 

② Centralized Command Center
Manage your entire water production from one beautiful, integrated panel. Featuring oversized high/low-pressure analog gauges and a precision flow meter, the Pro300 allows you to monitor system health and adjust output at a single glance with 100% mechanical certainty.

③ Quad-Membrane Efficiency (4x SW2540)
By utilizing four industrial-grade 40-inch membranes in a specialized 2-parallel-2-series design, the Pro300 maximizes freshwater recovery while significantly improving the quality of the produced water. This configuration greatly extends the lifespan of the RO membranes by optimizing pressure distribution. Furthermore, the modular layout allows these four vessels to be mounted in various configurations (stacked or distributed), making it surprisingly easy to install even in complex engine rooms.

④ Engineered for Continuous Offshore Duty
Equipped with a powerful, high-performance motor and a premium marine-grade SS316L high-pressure pump, the Pro300 is built for continuous, heavy-duty operation. It handles the stresses of high-capacity desalination with ease, ensuring stable performance in water temperatures from 4°C to 38°C.

⑤ Built for the Real World
We’ve intentionally avoided fragile touchscreens and computerized sensors that often fail in the harsh, salty environment of an engine room. The Pro300 relies on rugged manual valves and mechanical gauges, ensuring you can always make water, no matter the conditions.

Application

The Ultimate Choice for Large Yachts, Charter Catamarans, and Commercial Vessels (50-80+ ft).

The Pro300 is the premier solution for vessels with high occupancy or water-intensive luxury amenities. Its modular nature provides the flexibility to fit a commercial-grade plant into the available nooks of a private yacht, ensuring total freshwater independence for the most ambitious voyages.
