"Since 3 years we have an ECHOTec installed like most cruisers we know. After more than 25.000 liters produced, we as well as all our friends have no problems with your desalination system. Therefore, we have decided to use an ECHOTec watermaker again on our new project: the first circumnavigation on an electro-powered catamaran without sails and any fossil fuel."
Michael Köhler, MV "Solarwave"

"The reason for choosing an ECHO Tec. water maker is the well thought-out simplicity of the system, the rugged components that are used and the availability on site of knowledgeable technicians, along with a competitive price."
John Van Logchem, SY "Queen of Hearts"


"Having recently passed Captain Cook's "Thirsty Sound" inside Australia's Great Barrier Reef it seemed a good time to send a note thanking you for my excellent water maker.  Given the choice I shall never sail without one.  There are surprisingly many boats with your equipment on board and without exception we are all very happy with our water-makers and the excellent and prompt back-up you have given us."
