What is a PSU?
PSU or Pressure Supply Unit and is ‘part one’ of the two part system that makes up the complete rainman watermaker.

How To Choose Your PSU
115V or 230V PSU’s
By far the most popular selection and requires nothing more than a small portable generator or larger to operate (such as the honda EU2000 or EU20). If you have this AC power, it is recommended that you opt for the AC PSU.
The Gasoline PSU requires no external power at all, so is ideal for vessels that have no source of power, or owners looking for a truly portable desalination system. The system is operated from its onboard Honda 4 Stroke engine.
12V DC PSU
The 12 V DC PSU requires Batteries & Solar/Wind to provide 33Amps / 400Watts of power for operation – this is a lower output system with a maximum capability of 7-9 GPH.
Can I Install The PSU?
Yes! The AC and DC PSU’s come in either a Portable or Naked configuration. The Naked systems come with a comprehensive installation hardware package, where the portable systems come complete with high impact polyethylene casings.
You can also remove the casing of the portable system if you choose to install at a later date, and vice versa.
