RO Seawater Desalination Systems for Yachts and Commercial Vessels
|
|
|
| |
 |
|
Designed to reliably endure extreme marine conditions, far from factory-trained service centers, the ECHOTec PRO-Series provides small to medium sized commercial vessels and larger yachts with a dependable source of high quality potable water.
Simple self-installation, if required and minimal maintenance effort and operators’ input are the key features of these field proven watermakers.
|
|
|
Because only track records count, ECHOTec PRO-Series desalination systems are built without finicky electronics or touch screens.
Despite the multitude of standard and optional system features such as real time salinity monitor, hour meter, low/high pressure safety shut off, fresh water flush and failsafe product diverter, all functions are controlled by rugged mechanical components and low voltage electrical circuitry – more reliable and field repairable wherever you go.
For freshwater capacities of more than 3600 GPD/13,600 Liters, the installation of any number of redundant operative BHL desalination modules provides unlimited output. More economical than a single large system, multiple desalination modules provide back up, ease transport as well as installation and reduce the electrical start up load by more than 40%. In times of low water demand, only the modules needed are operated for lowest maintenance effort and ultimate cost efficiency. Upgrades are easy, fast and available in 1800 GPD and 3600 GPD increments.
The newly engineered marine aluminum frame provides tidy appearance while allowing easy access to the system components for maintenance. The semi-modular bulkhead mount systems or the self-contained vertical framed systems are space saving and almost turnkey, so that people without engineering background can install them.

Product water from any RO watermaker is extremely pure, has little salt content, is very soft and acidic due to the removal of alkaline mineral constituents of the seawater. Therefore, similar to rainwater, using RO product requires significantly more freshwater to rinse off soap, shampoo and other detergents.
ECHOTec is the first watermaker manufacturer to combat this problem by improving the RO product quality with a standard supplied post treatment system. The newly developed mineral dispenser returns some hardness to the water and offers a practical, low maintenance solution that saves up to 50% fresh water.
The ECHOTec post treatment element also contains a mixture of minerals that returns bicarbonate alkalinity, correcting pH only enough to reach a neutral equilibrium. This dramatically reduces corrosion on metal tanks, boilers, washing machines and plumbing due to acidic product water.
As the water is slightly re-mineralized, this will also improve the taste of the product water.

"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."
|
“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.” Read More Testimonials
