We have a watermaker for sale. It is about 10 years old and always worked very good. We installed new membranes, a new pressure pump and a new power supply card last winter, but have not used it much this year, since it got harder and harder to start it up. The last months it did not start up at all. The dealer says it needs a service and probably a new set of gaskets. So its a good system for somebody who is able to fix the minor problems himself.
The cool thing about the Schenker 30 Modular is that it runs with 12 Volt and (because of the clark pump) it only draws about 8 amps while producing 8 Gallons per hour. Its a similar system to the Spectra Watermaker.
Its pretty much the same as this, just the older model: SCHENKER dissalatori watermakers desalinators dessalinisateur wassermachers
We will be in Florida (Fort Lauderdale / West Palm Beach area) around Jan 20th till the end of the month.
