What it costs to run
A four-person crew using 25 litres a head needs 100 litres a day. On this system that is:
0.8 hrun time per day
984 Whenergy per day
0.6×400 W panel-days
$43per L/hr of capacity
This is an AC system, so it needs a generator, shore power or a large inverter. The Wh figure is what the generator has to cover.
Where it sits in the market
Ranked 12 of 30 rated systems on watt-hours per litre, where lower is better.

Common questions
- How much power does the Rainman Modular AC 140L use?
- It draws 1,250 W and makes 100–154 L/hr, which works out to 9.8 watt-hours per litre. Making 100 litres — four people at 25 litres a head — costs about 984 Wh.
- How long does the Modular AC 140L take to make a day's water?
- At its rated 100–154 L/hr, 100 litres takes about 0.8 hours. Output falls in cold or silty water, so treat that as a best case rather than a promise for every anchorage.
- How much does the Rainman Modular AC 140L cost in Australia?
- Our indicative figure is $5,460, taken from the manufacturer's published US list and excluding freight, duty and installation. Australian dealer pricing is usually all-inclusive and reads higher. Ask a stockist for a landed AUD quote before you budget.
- Who sells the Rainman Modular AC 140L in Australia?
- 20 verified Australian businesses are listed as Rainman dealers or specialists, including Rainman Desalination, The Watermaker Man, M Water Marine & RV. Each entry links to the manufacturer or company page that proves it.
- Is the Modular AC 140L efficient?
- It ranks 12 of 30 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.
