Is the freshwater production indicated on the product sheet identical to that actually observed?

The stated production is measured under optimal conditions: seawater at 25°C and salinity of 35 g/L. Under these conditions, the machines can even exceed the values displayed in the technical brochures. However, in real conditions, production may vary depending on several factors:

  • Water temperature : the hotter it is, the higher the flow rate; the colder it is, the lower the flow rate.
  • Salinity : Saltier water reduces flow, less salty water increases it.

These variations remain around 10%. Other factors such as filter clogging or pressure also influence performance.

What is the electrical power required for the 35 l/h and 65 l/h models?

For FIJI models with energy recovery , the power consumption is as follows:

  • 35 l/h : 12 V – 12 A.
  • 65 l/h : 12 V – 25 A, or 24 V – 12.5 A, or 48 V – 8 A.

These values are given for information purposes only and may vary depending on conditions of use.

For conventional PIANA models (30 to 90 l/h) , a generator of at least 4 KVA is required for start-up.

Can you run a watermaker 8 hours a day with solar panels?

Yes, it is possible, but it depends on the model and the energy configuration:

Energy recovery models (FIJI range) : particularly suitable for solar power, thanks to their low consumption and the possibility of direct connection to batteries. They are designed for daily use of 3 to 5 hours .

Conventional models (PIANA range) : less suitable for solar energy due to higher consumption. They require a 4 KVA generator to start and can be used up to 20 hours per day .

Are there any reliability differences between energy recovery and high pressure models?

Yes, both types have different advantages:

Energy recovery models (FIJI) :

  • Wear parts are protected.
  • Quiet operation.
  • Low consumption, no need for a generator.
  • Ideal usage range: 3 to 5 hours/day.
  • Ideal for sailboats and solar installations.

High pressure models (ARUBA, PIANA) :

  • More robust, designed for intensive use.
  • Use CAT high pressure pumps known for their durability.
  • Noisier, requires a generator.
  • Usage range: up to 20 hours/day.

The choice will depend on your lifestyle, your need for energy autonomy and the desired frequency of use.
