Dessalator D100 DUO
Reported figure, not yet confirmed by us. The output and draw above are published by the manufacturer and corroborated across independent lookups, but we have not yet read them page-in-hand the way we have for the rest of the table. It is shown so the system can be compared at all, and excluded from our best-and-worst-in-table claims until confirmed. Dual-power unit. This row is the DC mode at its stated 700 W maximum; the AC motor is rated separately and is not tabled. How we source figures.
What you are actually buying
Drawn to this model’s own published specification: modular, with a membrane count the manufacturer does not state, and a pump driven by a 12/24V DC motor.
What it costs to run
A four-person crew using 25 litres a head needs 100 litres a day. On this system that is:
DC systems have to fit inside the energy your solar, wind and alternator can spare. Run the numbers against your own bank in the calculator.
Is it worth it?
At 7.0 watt-hours per litre it sits mid-table: 1.9 times the energy of the most efficient system we rank, and about 2.8 times less than the thirstiest. 700 Wh puts 100 litres in the tank.
Suits
- Filling tanks in a short window. At 100 litres an hour, 100 litres takes 1.0 hours — the length of an engine run you were making anyway.
- 12 volt boats with no inverter. It runs straight off the bank, drawing about 58 Ah a day at 100 litres.
- Awkward spaces. The modules mount separately, so they fit around obstructions a single frame will not clear.
Look elsewhere if
- Boats you cannot drill. This is an installed system: intake, seacock, brine discharge and a wiring run, quoted separately from the unit.
Worth pricing against it: Schenker Zen 100 makes 100 litres an hour at 4.0 Wh/L, so the same 100 litres costs 300 Wh less every day. See the Zen 100 →

Where it sits in the market
Ranked 7 of 34 rated systems on watt-hours per litre, where lower is better.
A conventional high-pressure pump, but with enough membrane area behind it to keep the energy per litre reasonable. How the two technologies differ →

Common questions
- How much power does the Dessalator D100 DUO use?
- It draws 700 W and makes 100 L/hr, which works out to 7.0 watt-hours per litre. Making 100 litres — four people at 25 litres a head — costs about 700 Wh, or roughly 58 amp-hours from a 12 V bank.
- How long does the D100 DUO take to make a day's water?
- At its rated 100 L/hr, 100 litres takes about 1.0 hours. Output falls in cold or silty water, so treat that as a best case rather than a promise for every anchorage.
- Who sells the Dessalator D100 DUO in Australia?
- 2 verified Australian businesses are listed as Dessalator dealers or specialists, including Marine Tech Electrics, Yard Engineering. Each entry links to the manufacturer or company page that proves it.
- Is the D100 DUO efficient?
- It ranks 7 of 34 rated systems in our table on watt-hours per litre, where lower is better. The best in the table is 3.7 Wh/L. It uses a conventional high-pressure pump, which is the main reason it sits above the energy-recovery systems.
- Is the Dessalator D100 DUO worth it?
- At 7.0 watt-hours per litre it sits mid-table: 1.9 times the energy of the most efficient system we rank, and about 2.8 times less than the thirstiest. 700 Wh puts 100 litres in the tank. It suits several cases: Filling tanks in a short window. At 100 litres an hour, 100 litres takes 1.0 hours — the length of an engine run you were making anyway. Look elsewhere if: Boats you cannot drill. This is an installed system: intake, seacock, brine discharge and a wiring run, quoted separately from the unit. We publish no opinion on build quality or reliability, because we have not tested it.
