Welcome to cruisersforum, Hector.

You could have started off your question, like this. Like what general part of the world you're located at? Cause that could be a big factor on buying and possibly shipping the watermaker and the radio to where you're at?

Hector:
Do you want to make 300 Gal of fresh water over a 24 hour period (12.5 Gal./Hr.), or in some other shorter period?

Single Side Band (SSB) range is generally reliable to a 150 mile maximum (2-3mHz MF band) , though HF band can sometimes reach thousands of miles. I suspect you’ll have to use Short Wave (amateur, or HAM) radio, or satellite telephony for 3000 mi. communication range.

Thanks you for your answer.

I need about 300 Gal daily... each day...

About radio... Yes, I think I need a HAM... but I´m absolutly new in this job... and I dont know avsolutly nothing !!! Is because this is my first approach...

Hector, what you want may or may not be possible.

Are you fitting out a cruise liner? Harbor tug? 36' sailboat? For commercial use? Private use? Radio for occassional safety? Business use? High amount of traffic?

Give us all some details, you'll get better answers.

A brief overview of Watermakers:

Most R/O Membranes in the marine market are manufactured by Filmtec* http://www.dow.com/liquidseps/index.htm
, a subsidiary of Dow Chemical. Membranes are designed to work at a certain flow rate and pressure. Significant deviations from these design parameters will result in lower-quality product water (higher levels of dissolved solids) and shortened membrane life (increased fouling). A higher-rated membrane, operated less (or at lower pressure) will last longer.

Filmtec membrane #SW30-2521 is rated 200 GPD, and the #SW30-2540 is rated 540 GPD.

FYI: Excerpted from a PM from Hector:
”...I have a fishing ship and it needs a watermaker and a communications equipemente.
Effectively, the water needs daily are aprox 300 Gal
And the fishing area is about 3000 miles from the port, in Costa Rica...”
