Before choosing the right AQUAbibe watermaker, you should consider the following factors:

- What power source is available on your boat to operate the watermaker? (DC or AC?)
- In which area do you primarily operate your boat? (Coastal cruising or bluewater sailing?)
- What is the size of your onboard freshwater tank, and how quickly do you currently consume this water? Keep in mind that water consumption usually increases once a watermaker is installed – as water becomes easily available.

Based on your answers, we will be happy to help you find the optimal AQUAbibe watermaker for your boat.

Thanks to the modular design of our AQUAbibe watermakers, you have maximum flexibility when installing the system on board.

There are virtually no limitations – with one important exception: a seawater intake (seacock) must be installed at the lowest possible point in the hull. This ensures that the low-pressure pump is continuously supplied with seawater without air entering the system, as air can damage both the membranes and the high-pressure pump. Ideally, the low-pressure pump should be installed below the waterline.

Another important consideration is to keep both low-pressure and high-pressure hoses as short as possible, as excessively long hose runs will increase the required energy consumption.

AQUAbibe watermakers operate with 220 V AC / 50 Hz for the high-pressure pump and 12 V DC for the low-pressure pump.

The systems are designed to run on small portable generators, such as the widely used Honda EU22i (formerly EU2000i). With such a generator, the watermaker can be operated reliably while simultaneously charging the onboard batteries.

Alternatively, operation via onboard batteries in combination with a properly sized inverter is also possible, for example with a Victron Energy Phoenix Smart 12/3000. This configuration has been successfully tested by us.

Modern LiFePO₄ battery systems are particularly well suited, as they can easily provide the required power.

As with all high-power consumers on board, the electrical installation should be properly dimensioned and professionally executed to ensure reliable operation.

As a general guideline, one person on board consumes approximately 30 to 50 liters of water per day. This includes drinking water as well as water for showering, cooking, dishwashing, and other uses.

A crew of four therefore requires at least 120 liters of water per day.

However, experience shows that after installing a watermaker, this same crew typically consumes around 200 liters per day. Previously measured water usage almost always increases, as water becomes virtually unlimited.

The fresh water produced by an AQUAbibe watermaker is safe to drink.

Through the reverse osmosis process using a semipermeable membrane, only pure drinking water passes through, with a TDS value* of approximately 100 to 270 ppm.

According to the WHO, water with a TDS value of up to 1000 ppm is safe for consumption. Countries such as the UAE and the Bahamas are supplied entirely with water from desalination systems (watermakers).

A common question concerns essential minerals, which are largely removed during the RO process. This is not a concern, as most of the required minerals are obtained through food intake.

* TDS: Total Dissolved Solids – a measure of the mineral content in water

Several factors play a role here. In general, a seawater desalination system should be operated regularly. At the same time, it requires energy during operation and generates noise.
The goal is therefore to run the watermaker at regular intervals, but for the shortest possible duration each time.
Ideally, it is sufficient to operate the system every two days for one to two hours to refill the water tanks.
If a crew requires around 100 liters of water per day, a watermaker with a fresh water output of approximately 100 liters per hour is the ideal choice.

All AQUAbibe watermakers require a 230V AC power supply for the high-pressure pump.

The NAVA CORE series does not require any additional electrical installation.
The NAVA PURE series additionally requires a 12V DC connection.

Due to the combination of feed pump and high-pressure pump, the NAVA CORE series has a higher startup current and can be easily operated with the specified generators, provided they deliver the required starting power.

Thanks to the separation of high-pressure pump and feed pump, the NAVA PURE series has a lower starting load and can therefore, in certain cases, also be operated via 12V DC inverters. For smaller units, inverters from 2 kVA are recommended.

Many modern sailing yachts are already equipped with generators, allowing AQUAbibe NAVA watermakers to be operated reliably at any time.

The modular design of AQUAbibe NAVA CORE and NAVA PURE watermakers allows installation even on smaller boats and in very limited spaces.

Instead of installing one large, compact unit, the individual components can be distributed flexibly within the hull (within certain technical specifications).

This design, combined with the high level of pre-assembly of all modules, enables a fast and straightforward installation of your AQUAbibe watermaker.
