Rainman vs Schenker
Rainman sells litres, Schenker sells watt-hours. If your engine or genset runs daily anyway, Rainman gives you far more output per dollar. If you are on solar and the engine only runs to anchor, Schenker's energy recovery is the difference between making water and watching the bank sag.

Rainman in one line
The default in Australian marinas. Portable, modular and framed versions of one pump platform, in AC, DC and petrol. Big output in a short window; efficiency depends entirely on which membrane pack you choose.
Schenker in one line
Modular DC systems built around Schenker's Energy Recovery System. The most efficient litres in the table, aimed squarely at solar-powered liveaboards and long-passage boats without a generator.
Common questions
- Is Rainman or Schenker more efficient?
- On best-in-range, Schenker at 3.7 watt-hours per litre against 9.8. The gap comes from pump architecture: energy recovery reuses the brine's pressure instead of dumping it overboard.
- Which is cheaper, Rainman or Schenker?
- Entry pricing starts at $4,402 for Rainman. Compare dollars per litre of capacity rather than sticker price, and remember an efficient system can pay for itself in the solar and battery you do not have to fit.
- Which is easier to service in Australia?
- Rainman has more verified stockists in our directory (20 against 1). Check who is local to you rather than the national count, and confirm whether they service or only sell.
