Our traditional system in the blue case can be used as either portable or installed. If you wish to install it, it becomes a two box installation. Various approaches that can be utilised include:

• Keep it portable, pulling it out and setting it up each time you wish to use it.
• Leave the unit in a locker, but pull out the hoses and throw overboard to make water, avoiding the need to move the system around on your deck.
• Keep the system portable, but use a cam-lock fitting to temporarily plumb the system into a teed deck wash fitting. This gives the benefits of an installed system while using your portable unit while underway.
• Fully plumb the system in, including the autoflush system

The system is made up of a pressure supply unit (PSU) and a reverse osmosis unit (RO).

Both parts are required to make a complete watermaker. The PSU lifts the seawater, filters out the sediment and puts the system under high pressure, while the RO unit extracts fresh water from the stream of pressurised seawater.

Most of the water goes out to waste as brine output, while about 20% of the volume is extracted as fresh potable water for your tanks.

Different RO options exist for you to select with your AC Rainman system, each to achieve their own specific objective.
