How Aqua Nautica Energy Recovery Works
How Energy Recovery Works
In a conventional reverse osmosis system, pressurized brine is discharged overboard, wasting much of the energy used to pressurize seawater.
Pressure Energy Is Reused
The Clark pump transfers pressure from the outgoing brine stream to the incoming seawater, significantly reducing the electrical power required to produce fresh water.
Reliable, Simple Operation
Reliability comes from careful engineering, durable components and years of manufacturing experience. The system is hydraulically self-regulating, requires no manual pressure adjustment during normal operation and does not require specialist skills for everyday use.
Built for Dependable Cruising
Aqua Nautica watermakers combine durable components, low power consumption and simple hydraulic operation for reliable freshwater production during long-distance cruising.
French-Designed Marine Watermakers
We use components from established manufacturers, including Shurflo, Amer, SKF, Fluid-o-Tech, Zilmet, FilmTec, Aignep, WIKA and ZEC. Aqua Nautica Clark pumps and other precision parts are produced using advanced CNC machinery.

Frequently Asked Questions About Marine Watermakers
-
What is a marine watermaker?
A marine watermaker is a reverse-osmosis system that converts seawater into fresh water on board a boat. It allows sailors to produce their own freshwater supply instead of relying entirely on marina facilities or stored water.
-
How much fresh water do Aqua Nautica watermakers produce?
Depending on the model, Aqua Nautica PRO watermakers produce between 30 and 110 liters of fresh water per hour. Rated performance is measured at a seawater temperature of 26°C (80°F) and salinity of 33 g/L. Actual output may vary depending on water temperature, salinity and system condition.
-
Are Aqua Nautica watermakers available in 12V and 24V versions?
Yes. Aqua Nautica PRO watermakers are available in 12V DC and 24V DC configurations, making them suitable for the electrical systems commonly found on sailboats and yachts.
-
Can an Aqua Nautica watermaker operate using solar power?
Yes, when the boat’s solar panels, battery bank and electrical system are properly sized for the selected model. Actual solar requirements depend on the watermaker’s power consumption, daily freshwater demand and available sunlight.
-
How does Clark pump energy recovery work?
The Clark pump transfers pressure energy from the outgoing brine stream to the incoming seawater. By reusing energy that would otherwise be discharged overboard, it significantly reduces the electrical power required to produce fresh water.
-
Do Aqua Nautica watermakers require electronic controls?
Aqua Nautica PRO watermakers are designed without electronic control systems. Their hydraulically self-regulating operation requires no manual pressure adjustment during normal use, which helps simplify operation and maintenance.
-
Which Aqua Nautica watermaker should I choose?
The right model depends on the number of people on board, daily freshwater consumption, available electrical capacity and intended cruising conditions. The AQUA 30 PRO is suited to lower daily demand, while the AQUA 60 PRO and AQUA 110 PRO provide greater freshwater output for larger crews and higher consumption.
-
Where can I buy an Aqua Nautica watermaker?
Aqua Nautica watermakers are available through our international distribution network, with delivery to destinations worldwide. Contact your nearest authorized distributor for pricing and shipping information, or contact Aqua Nautica directly for purchasing assistance, warranty information and spare parts.
