RAINMAN 12V POTABILIZER
PRESENTATION
The Rainman 12 VDC watermaker is the most energy efficient watermaker.
It is a very simple and highly reliable system that can produce up to 34 liters (9 gallons) of drinking water per hour.
There are options for the water treatment system to work completely portable, without any installation, or completely fixed.
Our 12 VDC system is a great option if you don't have AC power available but want to avoid the complexities and maintenance requirements of more efficient energy recovery systems.
A WATER TREATMENT PLANT WITH ONLY 2 COMPONENTS
The system is comprised solely of a Pressure Supply Unit (PSU) and a Reverse Osmosis (RO) unit.
Both parts are necessary to assemble an entire water treatment plant. The feed pump lifts the seawater, filters sediment and puts the system under high pressure, while the reverse osmosis unit draws fresh water from the pressurized seawater flow.
Most of the water is wasted as brine output, while approximately 20% of the volume is withdrawn as drinking water for its reservoirs.
There are different membrane options for you to select with your system, each to achieve its own specific goal.
ENERGY
With recent advances in batteries, solar and wind power, it's easier than ever to have enough amp-hours available to run your equipment.
Our 12V DC system requires only 410 watts, or about 30 amps, to run.
FIXED OR PORTABLE INSTALLATION
Our system is supplied in a blue casing/case that can be used as a laptop or left attached. If you want to install it, it becomes a 2-item installation only.
Use it in a totally portable way, put it away and every time you want to use it, you will have it up and running in as little as 2 minutes.
The lid of the membrane housing is opened, and the hoses are removed. Throw them overboard to suck up water, and connect the membranes to the pressure equipment through 1 single pipe with quick connect. That's it, connect the power supply and you can now generate drinking water.
Another option would be to make a fixed installation using grommets and connect the pipes to the grommets.
MEMBRANE OPTIONS
Due to the lower flow of the 12V power unit, only the 40″ diaphragm, the Economy unit, is allowed to be used either with the blue housing or without the housing for fixed mounting.
This system will produce 7 to 9 gph (26 to 34 liters per hour).
HOUSING OR NO HOUSING
The system can be purchased in the blue casing version or in the casing-less version. Price, performance, and power consumption are identical between the two options, so your specific requirements will decide which is best suited for each application. The following table summarizes the differences between the two options.
