Applications

MARINE - Marine applications - Click here to be taken to our marine applications page.
SURVIVAL - When disaster strikes, entire villages may be found completely isolated, without electricity, and without fresh water. Without preparation, the entire village can be in a dire struggle for life. In survival situations, fresh water is at the top of the priority list after immediate physical danger. Acquiring a Rainman watermaker is a small investment for communities potentially exposed to cyclones and other natural disasters.
OFF GRID - If you live in a remote area or go on extended expeditions, chances are you have been in situations where you only have brackish water. Brackish water will often contain a variety of particulates, bacterias, or tannins. Reverse osmosis is the most thorough way to ensure your water is drinkable.
MILITARY - Militaries around the world use reverse osmosis as their default filtration system. When space and weight is a premium, militaries need the smallest and lightest portable system available. Rainman desalination is the most portable system around.
