Belt Driven Watermakers (Modular)
|
The Belt Driven Systems are ideally
suited where the main engine runs more than once a week. They produce
21 - 64 gallons per hour of fresh water even on a small yacht without
a generator.
Instead of draining your batteries you will charge them every time
you run the engine and make tons of water at the same time.
An additional pulley and space for the quite small high pressure
pump on the motor is required.
The supplied U-brackets help to install the pump
on the engine like a second alternator.
|
ECHO Tec. belt driven watermakers are equipped
with a patented automatic pressure regulating valve.
This device ensures constant working pressure on changing engine RPM, a must on every propulsion engine driven watermaker. All wetted components including the high pressure pump head, the regulator and all high pressure fittings are made from Duplex stainless steel.
For economical maintenance ECHOTec does not use proprietary components that bound you to purchase expensive consumables only available from the original manufacturer.
Standard filters, chemicals and membranes can be obtained anywhere. |

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.

"You installed a modular engine driven system in my Peterson 44, Endymion in 2002. It has worked wonderfully ever since. I am still on the original membranes and I don't treat them very well.
A robust system"

“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

"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."
