ECHO Tec. Watermaker

AC Watermakers for Yachts   (Modular)

The ECHO Tec. AML/S Series desalination system is a well proven cruising gear for yachts with single or 3 phase generators of 5 KW or larger. Designed by and for cruisers, these rugged yacht watermaker was continuously improved since its introduction in 1997. It has proven ultimate reliability and longevity in more than 40 million combined real world operating hours.

Innovative system features like pH neutralizing post treatment,
O-ring sealed high-pressure connectors throughout the system and field attachable high-pressure hose fittings for easy self installation, together with low purchase/maintenance cost and cruiser friendly after sales service have made ECHOTec modular AC watermakers
the logical choice for boaters worldwide.

AC Modular Watermaker

Like with the largest ECHOTec watermakers, an extremely quiet operating stainless steel triplex ceramic plunger pump is heart of the AML/S systems. The ECHOTec pump is a low revolution, low friction custom version, driven by a highly efficient NEMA Premium WATTSAVER AC Motor, designed for continuous duty under tropical conditions.

For economical maintenance we do 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. These desalination systems are engineered without "bells and whistles" for live aboard offshore cruising with peace of mind.

Choose wisely a watermaker - Article by Sam Mazza - Blue Water Sailing

"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."
