Rainman Framed Watermaker Systems

Our framed watermaker systems are designed for those customers that want an easier installation and have sufficient space to fit the entire system into a single location. Three different options are all powered by AC electric and have outputs between 100 and 230 litres per hour (26 to 60 gallons per hour).

Although the systems look different than other Rainman watermakers, internally, they are similar. The framed systems utilise the design simplicity found in all Rainman systems. A single motor with a through shaft to drive both the lift pump and high-pressure pump. Employing the same control panel and auto flush that are optional on our modular systems, the operation of the system is the same as any other installed Rainman unit.

Our framed systems were created to either be plumbed into your boat or used for land-based applications.

Frame AC 230 Torrent

Torrent is Rainman’s highest output watermaker that was created for those customers on larger vessels that require substantial amounts of fresh water and have more power available.

Incorporating three 2.5″ x 40″ seawater membranes, Torrent makes 180 – 230 litres per hour (48 – 60 gallons per hour).

Torrent has a larger 2.2/2.5 HP motor than our other AC systems. It can be wired for either 230VAC or 115VAC. Running on 2450 watts steady state at 50Hz or 2800 watts at 60Hz, we recommend a good quality 8kW generator to start and run the system.

Frame AC 140

This framed version of our most popular AC system has 2 x 40″ membranes and makes 100 to 140 litres per hour (26-37 gallons per hour). This high output watermaker will operate on a 2kVA generator or inverter. Many thousands of these systems have been deployed around the world in either portable or modular installed configuration.

This system has the same physical footprint as the Frame AC 230 Torrent above but uses less power and makes less water.

Frame AC 100

If you have limited width for your installation footprint, this system still provides reasonably high output using three 2.5″ x 21″ seawater membranes. It makes 75 to 100 litres per hour (20 – 27 gallons per hour) utilising a 2kVA generator or inverter.

It utilises the same frame, pumps and motor as the Frame AC 140 above, but with shorter membranes.

Most customers will enjoy the convenience of these systems being totally mounted in the frame. The membranes can be mounted on the rear or top of the frame. They can also be slid side to side as required.

If you have footprint issues and prefer the frame over a modular configuration, the membranes can be mounted remotely. The control panel and prefilters can also be removed and mounted remotely if desired. Note that mounting the components remotely will require you to get appropriate extension hoses as required.

If using the system on land, a 12-24VDC supply will be required for power the electronics and a house pump is required for auto flush operations.

Differences to Other AC Rainman Systems

The two smaller framed systems (100 and 140) are the same motor/pump configuration as our other AC portable and modular systems, but the larger one (230 Torrent) uses a larger pump/motor assembly to achieve great flow rates.

The main difference from the modular AC systems is that the framed units include the control panel and auto flush. These are optional items on the modular systems and not available for the portable units.

Control Panel

The included control panel provides a remote management capability for your Rainman framed watermaker. It’s a highly presentable and functional component that will enhance your Rainman user experience.

Control panel is an injection moulded ASA acrylic panel that remains true to Rainman’s reputation of elegant simplicity.

• Integration with the Rainman auto flush system, triggers flush cycle after powering the watermaker off.
• Built in tri-colour LED salinity sensor indicates when water is good to route to your tank.

Autoflush

Your Rainman framed watermaker is a very robust piece of equipment, but caring for certain aspects will prolong its life. Regularly flushing your Rainman with fresh water will maximise the life of your watermaker membranes.

The included auto flush system incorporates a solid-state programmable timer that will flush your Rainman watermaker after each use and every seven days thereafter. It incorporates built in protection if your boat loses power during or between flush cycles.

Optional Accessories

While the base system will be sufficient for many customers, a number of options are available to get more out of your Rainman watermaker.

• For new installations, you may need a sea strainer. This can be purchased as an option with your Torrent configuration.
• A hydrotester will give you indication of the total dissolved solids (TDS) so you can know how your membranes are ageing.
