Rainman System Builder

Only the best quality parts go into Rainman and we’ve built as much of the unit as possible in stainless steel.

PORTABLE RAINMAN WATERMAKERS:

The original portable Rainman Desalination System’s power supply unit provides the power and pumping ability to draw source water and then press it through the reverse osmosis membrane filter.

PRESSURE SUPPLY UNIT – ELECTRIC

115V / 60Hz

Ideal for those with generators on board.

Features include:

• It can draw seawater from up to 6 feet above sea level and pressurizes it up to 800 psi.
• Sturdy polypropylene shell
• Totally enclosed fan cooled (TEFC) induction motor
• Draws 1300 watts in steady state operation
• Optimized for Honda 2kW generator or higher
• Pre-filter and housing externally mounted for ease of service
• Jabsco impeller pump to lift water and provide positive pressure to the high pressure pump
• General Pump WM series 316 stainless steel high pressure pump, the workhorse of the RO industry
• General Pump relief valve to prevent over-pressurization and allow for pressure washing
• Sturdy 5 meter draw hose fitted with one way valve so it remains primed, with detachable strainer
• Four replacement 5 micron pleated paper pre-filter cartridges included 1kg (2.2 lb) bag pickling solution powder included
• Couples with one of our reverse osmosis membranes, ordered separately
• Can also be coupled with RO membranes from other suppliers

NEW INSTALLABLE RAINMAN WATERMAKERS:

PRESSURE SUPPLY UNIT – NAKED

Minimum Footprint Installation
If you want to permanently install your system, do not require future portability, the Rainman Naked watermaker is a good option. Any of the electric pressure supply units can come in the Naked configuration.

This system has the same internals and performance as the traditional Rainman system, with an integrated lift pump so there is only one motor to switch on.

The Rainman Naked system excludes the blue shells, and includes a variety of valves and hardware useful for your installation.

Three main components (pump/motor, pre-filter, RO unit) can be mounted separately from each other. The valve/gauge controls are to be mounted remotely, so the watermaker can remain out of sight.

Dimensions:

• AC PSU: Length 470mm (18.5″), Width 240mm (9.5″), Height 270mm (10.7″)
• 12VDC PSU: Length 470(18.5″), Width 240 (9.5″), Height 230 (9.1″)
• RO – Economy: Length 1,160mm (45.7″), Width 100mm (4.0″), Height 100mm (4.0″)
• RO – Compact: Length 660mm (26.0″), Width 200mm (7.9″), Height 100mm (4.0″)
• RO – High Output: Length 1,160mm (45.7″), Width 200mm (7.9″), Height 100mm (4.0″)

Note: The above photo shows the AC unit with Compact RO having valve/gauge assembly within the pressure vessels. This is for ease of display. The valve/gauge assembly would normally be at the end of another high pressure hose, and most customers would buy the longer high output RO membrane unit.
