AQUA 30 PRO – Compact 30 L/h Marine Watermaker
The AQUA 30 PRO is a compact, energy-efficient marine watermaker designed for sailboats and yachts. Its enhanced Clark pump energy-recovery system produces 30 liters of fresh water per hour while drawing only 11 A at 12 V DC or 5.5 A at 24 V DC. The fully mechanical, hydraulically self-regulating design helps simplify operation and maintenance.
Price excludes VAT, shipping and applicable taxes.
Description
Key Features
- Compact design: Weighs 25 kg dry and is designed for installation where onboard space is limited.
- Efficient freshwater production: Produces 30 L/h while drawing 11 A at 12 V DC or 5.5 A at 24 V DC.
- High salt rejection: Achieves a minimum salt rejection rate of 99.5%, producing water with less than 500 ppm TDS under specified operating conditions.
- Clark pump energy recovery: Reuses pressure energy from the outgoing brine stream to reduce electrical power consumption.
- Fully mechanical operation: Requires no electronic control system or manual pressure adjustment during normal operation.
- Wide operating range: Handles feedwater salinity up to 50,000 ppm and temperatures from 0.5°C to 45°C.
Why Choose AQUA 30 PRO?
Designed for sailors who need reliable freshwater production with low electrical demand, the AQUA 30 PRO combines compact components, mechanical operation and energy recovery. Its 30 L/h output makes it suitable for smaller crews and vessels with limited installation space and battery capacity.

Customer Experiences
“I was among the first customers to purchase a 25 L/h Aqua Nautica watermaker at the Paris Boat Show. The system was easy to install, and I completed the installation myself. It has reliably met our freshwater needs while sailing in the Mediterranean.”
M.G.
“The Aqua Nautica watermaker is robust and reliable. Its biggest advantage for me is its fully mechanical operation: there are no electronic controls, additional adjustments or risk of electronic failure. Online support is fast, with clear instructions, videos and photos.”
J. B.
“I compared several manufacturers but could not find a better combination of price and quality. Aqua Nautica watermakers were 30-40% less expensive than many alternatives while offering excellent build quality.”
V. P.
“I purchased an Aqua Nautica watermaker three summers ago on the recommendation of a charter company that uses these systems across its fleet. The winterization process is straightforward.”
P. D.
“My Aqua Nautica watermaker is the most important crew member on my round-the-world sailing journey.”
