SIZING YOUR SYSTEM
First, think in terms of GPH (gallons per hour) rather than gallons per day. The bottom line is that you want to run your engine or generator set as little as possible, make water, refrigeration and charge batteries all at the same time. Therefore, the duty cycle is critical.
If you can match your run time for water to that of batteries and refrigeration, you will maximize your engine and fuel efficiency. As a general rule, it is to your advantage to produce as much water in the shortest amount of time. When systems are sized too small, it requires additional run time to meet your requirements for potable water. This greatly detracts from your cruising enjoyment.
Quit rationing! Make it more efficient and maximize your fun!
Choose the AquaMarine svstem that best fits vour needs. Here is a broad list of capacities* that are available:
The average cruiser's daily consumption without rationing and including showers is approximately 7.5 gallons per day per person. Also, you must produce an extra 5 gallons per run to flush your system for maximum longevity of the components, particularly the membrane. Try the following guidelines. Also, build in a "fudge factor" for additional crew or system degradation as the system ages. We've rounded upward from 7.5 gpd per person to 10 gpd per person for plenty of leeway.
Note: Using the same criteria the 40 gph pump running for only two hours per day, twice a week will yield 150 gallons per week, 10 % more water in 33% less time! Bigger is better!Back to Top
In many boats, there is simply not the room to install prepackaged mainframe units without loss of valuable locker space or other vital storage. More importantly, while in a few cases these mainframe units may be easier to install, access to important maintenance items is very limited. Aesthetics, access for maintenance, and efficiency are all reasons for installing system sub-assemblies as offered by AquaMarine.
By installing your RO system as sub-assemblies, you are able to locate the pre-filters in an easily accessable location. The control panel can be remotely located exactly where you want it. The RO membrane can also be located in a low heat environment. In addition, keep in mind, when you do want to expand your fresh water production, in most cases you can easily add an additional RO membrane!Back to Top
Electric driven systems at best provide a maximum of 60% efficiency because of the conversion from mechanical to electrical and back to mechanical energy. This is why at 93% to 95% efficiency it is better to belt drive the RO high pressure pump directly from the main engine or generator requiring less space, weight and maintenance.
