The right choice starts with demand
Do not buy by boat length alone.
The useful answer comes from crew size, daily water habits, desired running hours and the energy available aboard.

Clark pump energy recovery
The pressure that normally goes overboard goes back to work.
Conventional reverse osmosis discards pressurized brine. Aqua Nautica uses that pressure to assist the next pumping cycle, dramatically reducing the electrical power required to desalinate seawater.
- 1Pressurize seawater
The feed circuit supplies the reverse-osmosis membrane.
- 2Separate fresh water
Fresh permeate is produced while concentrated brine exits.
- 3Recover the pressure
The Clark pump transfers brine energy to incoming seawater.
◉
Result: lower DC demandMore of the boat's stored energy remains available for everything else.

Before you choose
Questions serious buyers ask.
Clear answers reduce risk before the quotation and installation planning stage.
Can Aqua Nautica watermakers run from batteries and solar?
The PRO Series operates on 12V or 24V DC and is designed around low-energy operation. Final battery, cable and solar sizing depends on the selected model and the vessel's electrical system.
Do I need to run a generator?
A correctly sized DC installation can operate without a generator. The Clark pump recovers pressure energy from the brine stream, substantially reducing electrical demand.
Which model is right for my boat?
The best choice depends on crew size, desired daily water production, available running time, voltage and charging capacity. Send those details and Aqua Nautica will recommend a model.
Can an owner install the system?
The systems are designed for straightforward installation and include detailed instructions. Installation must follow the current manual, vessel requirements and good marine practice.
Is worldwide delivery available?
Aqua Nautica supplies customers through its distribution network and offers worldwide delivery. Freight, local duties and the installation scope are confirmed with the quotation.
What support is available after purchase?
Online customer support, warranty service and spare parts are available. The hydraulic, electronics-free design helps owners and technicians understand diagnosis and routine service.
