DUO (AC & DC) WATERMAKERS - 12/24v and 120/230V

Patented models

The DUO is the first bi-powered watermaker system world-wide.

It functions at the turn of a switch on D.C. (12 or 24V) and on A.C. (120 or 230V), as the DUO is an intelligent patented system.

Thanks to this system, the motors operate independently from each other, with neither electric clutch activation nor manual manipulation of the pulleys. Like all Dessalator products the DUO is 100% reliable and safe.
For more than 10 years the DUO 60 and DUO 100 are mounted in batches by the large shipyards and are the choice for navigators.
The advantage of the DUO is its "2 in 1" aspect, as if there were two water makers available with the facility to function optimally and logically.

For example: When there is no wind and the engine is running, D.C. power (at 12 or 24V) is available and should be used (DUO 60: 370W, DUO 100: 600W).
At anchor, when the power generator is running the watermaker can be operated on the A.C. supply (230V).

Its slow consumption (DUO 60: 5A, DUO 100: 6,5A) allows keeping the whole charger power for recharging the batteries and other uses (for instance: hot-water tank).

Only the hull valve with strainers is delivered standard. The remaining valves can be delivered on demand as most of the times the waste outlet pipes are connected to existing waste outlets and the fresh water departures often have their own closing valve.


DESSALATOR® products are delivered complete with all accessories. All components meet current EEC standards:

  • Strainer and hull valve
  • Solenoid valve for automatic rinsing
  • Pre-filter filtering out solid particles up to 5 µm and its wrench
  • Fuse or circuit breaker according to the model
  • HP piping: 2 hoses and 4 special DESSALATOR® connectors
  • Piping for the production of fresh water from membrane to panel.
