Rainman Portable Electric watermakers are available in both AC and DC power.
The Rainman DC Electric system is the most power-efficient watermaker in the Rainman range. Simple and highly reliable, it’s available in both 12VDC and 24VDC options. This system offers the flexibility to be used either fully portable, without any plumbing, or installed with minimal footprint and full plumbing. It’s an ideal choice when AC power is unavailable, offering a straightforward solution without the complexities or maintenance demands of more advanced energy recovery systems. The 12VDC system produces up to 34 liters (9 gallons) of fresh potable water per hour, while the 24VDC system can produce up to 55 liters (15 gallons) per hour.
The AC system is by far our most popular watermaker. It’s a very simple and highly reliable system that can make up to 140 liters (37 gallons) of fresh potable water per hour. Options exist for this system to be run as portable without any plumbing or plumbed in with a minimum footprint installation. The AC system is a great option when you want to make a lot of water quickly and get back to enjoying yourself.
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.
Rainman AC systems come in either 230VAC/50Hz or 115VAC/60Hz. This covers the vast majority of the AC power set ups around the world ( the Philippines is an exception). These systems are almost identical, except the two factors.
The AC induction motors are manufactured for either 230VAC or 115VAC. The shafts on the high-pressure pumps have different throw lengths, optimizing the system for either 50Hz or 60Hz operation.
