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.

As for all other ECHOTec watermakers, only the 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 the 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.

How Many Watts Does a Watermaker Use If It’s a 12V Watermaker?

As you can see from the above diagram, the amount of watts that a watermaker uses is directly proportional to how many gallons of fresh water it will be producing. In this case, the amount of power that it produces is calculated in amps.

There is a simple formula to calculate how many watts this 12v marine desalination system uses. The wattage in one amp depends on the voltage of the system. Using the formula for DC conversion: Watts = Amps x Volts, at 120 volts, 1 amp would equal 120 watts. 

At 12.5 volts, 19.5 amps would use 247.5 watts, 27 amps would use 337.5 watts, 38 amps would use 475 watts, and 80 amps would use 1,000 watts. You can use this formula to calculate how many watts you would need to produce electricity and determine if you have the capability to do so. 

What Makes This Model One of the Best DC Watermakers for Yachts?

At the heart of our design philosophy lies a commitment to compact efficiency without compromising on performance. Our system boasts a sleek and space-saving profile, making it an ideal solution for vessels where every inch counts. The 12V power supply ensures seamless integration with your yacht’s electrical system, providing an on-demand freshwater oasis in the open sea.

Beyond its modest footprint, simplicity defines our desalination system—engineered for ease of use. With user-friendly controls and a hassle-free installation process, even novice sailors can effortlessly harness the power of the ocean to meet their hydration needs. This 12v marine desalination system is the best option for people looking to enjoy compact desalination. 

Why Are Small DC Watermakers for Yachts Better?

Small DC watermakers for yachts represent the epitome of convenience and efficiency in on-the-go desalination solutions. Their compact design is a game-changer for yacht owners, allowing for seamless integration into limited onboard spaces. The 12V DC power sources not only align perfectly with a yacht’s electrical systems but also ensure energy efficiency, making these sustainable choices for extended journeys.

Can You Drink the Water From a Watermaker on a Boat?

Absolutely. The water produced by our advanced watermakers on boats is not only safe but exceptionally pure. Our cutting-edge desalination systems effectively remove salt and impurities from seawater, delivering high-quality, potable water for onboard consumption. 

Can You Run a Watermaker While Sailing?

Yes, a 12-volt marine water maker can run while sailing. In fact, many boats can only run electricity when the engine is on, making this a viable solution for many sailors and boaters. By leveraging the vessel’s 12V power system, our watermakers provide a self-sufficient solution, converting seawater into drinkable water during your entire sailing journey.

How Does a Superyacht Get Freshwater? 

If you own a superyacht or are interested in getting a desalinator for sailboats, you might need a larger desalinator, much like a home desalination system. Some of our popular options for superyachts are the following:
