Rainman
Rainman Watermakers, are compact in design, which generate fresh potable water from seawater. They can be installed engine room with minimum footprint configuration or kept portable for maximum flexibility.
Rainman Watermakers use top quality components from leading manufacturer to build the system. This includes Honda, General Pump, Filmtec, and Noshok. The filters, membranes and replacement parts are non-proprietary for ease of service worldwide.
Rainman offers three option for the power sources. They are the AC electric, petrol (gasoline), and 12VDC electric. The below table shows the specifications of the various options.

Applications
Marine
Demand for fresh water on Sea has increased dramatically in recent decades. Many of us now expect daily fresh water showers, pressurised plumbing, and unlimited drinking/washing water. Until now, the only option has been a complex system built into your boat. The high cost, complexity, and maintenance requirements of such systems have been daunting. At Rainman Desalination, we have developed the world’s first simple, low maintenance, and inexpensive water maker that doesn’t need to be installed in to your boat.
Remote Area & Emergency Response
Living in small remote areas, 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.
Sodium Metabisulfite Pickling Solution Mix
With proper care, your reverse osmosis membranes will last for years. Due to the nature of reverse osmosis, the membranes self-clean while the system is in use. However, when the system goes unused for an extended period of time, the membranes need to be “pickled” to ensure bacteria doesn’t grow inside and damage the membranes. The powder itself is sodium metbisulfite and dissolves easily in cold water. It is safe and widely used in the food and beverage industry. This chemical is widely used and available easily from home brew and wine making retailers, among others. The length of time your system can sit idle without pickling is largely dependent on air and water temperature.
Jabsco Lift Pump Replacement Impeller
The lift pump in any of the Rainman pressure supply units contains a small rubber impeller and is considered a consumable item. Life of the impeller will vary with use, but in general it might require changing every couple of years.
Spare Parts & Consumables
Consumable Part
PLEATED PAPER 5 MICRON PRE-FILTER CARTRIDGE. The life of your pre-filter cartridge will depend largely on the source water being used. Drawing water out of the open ocean may allow your pre-filter cartridge last for several months, while drawing from polluted bays may foul your cartridge within hours of use. The cartridge is a 10" x 2.5" 5 micron pleated paper filter. These inexpensive cartridges are widely used and available throughout the world from water filtration retailers and hardware stores. Please note it is very important to use a 5 micron filter with this system to protect the RO membranes and the high pressure pump.
