ECHO Tec. Watermaker

DC Watermakers for Yachts - 12V, 24V, 36V, 48V, 90/96V, 144V and 180V (Modular)
from 8.5 GPH to 75 GPH/1800 GPD

With the release of the new 12 / 24 Volt Watermaker 200-DML-1, ECHOTec achieved a breakthrough in efficiency for watermakers, utilizing ultra-reliable triplex ceramic plunger pumps.

The ECHOTec. pump is a low revolution (570 RPM) stainless steel version, driven by a highly efficient permanent magnet motor, designed for continuous duty under tropical conditions.

No low reliable and service intensive energy recovery pumps or irreparable electronic circuits that can stall the entire system are used on any ECHOTec yacht watermaker.

These desalination systems are made without "bells and whistles" for live aboard offshore cruising and racing with peace of mind.

        "KITCAT" Leopard 46 - ECHOTec. 260-DML-1

As for all other ECHOTec watermakers, only highest quality raw materials that have proven to withstand continuous duty in a harsh marine environment are selected for ultimate reliability and lifetime. Therefore, we fabricate all wetted components including the true regulating pressure valve and all high-pressure fittings from high-grade austenitic stainless steel.

For most economical maintenance and global use, we do not fabricate components to proprietary dimensions. Standard filters, membrane elements and many spare parts can be obtained anywhere.

    "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."
John Kirkus, SY "Bluesipp"

"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"


    "I can’t thank you enough for seeing us through the installation and for designing and building such a high quality watermaking system. I was eager to get the word out about Echotec to future cruisers, which is what prompted me to write an article about the system for Cruising World."
Emily, SY "Groovy"
