Spot-Free Benefits

Since dried dissolved solids in water are what leave water spots, removing them is crucial to a true spot-free rinse and to the rest of the benefits purified water can provide to a vessel.

No More Hand-drying

Rinse your vessel down to a spot-free shine with no need to chamois-dry surfaces, saving you and your crew both time and money.

Protect Finishes

Extend the life of wax, paint and other finishes throughout your vessel. Chamois remove wax and rub leftover solids into your finishes. In the long run, this can save thousands of hours and dollars in maintenance and refinishing.

Simple & Clear to Use

Enjoy an easy-to-use LCD controller with digital ppm and temperature readings, as well as flow meters before /after pressure gauge for 100% clarity of how the system is operating.

Cruise in Comfort

Cook, drink and make ice free of water-born contaminants. You can also bathe, wash clothes, clean dishes and more without concern for scaling, mildew or lime build-up. Achieve the same spot free benefits you can expect on your exterior finishes on the inside!

Removes up to 99% of TDS

Remove up to 95-99% of total dissolved solids (TDS) from any dockside or on-board water supply. The result is soft, pure water for a spot-free rinse without the need to hand-dry.


Recover 66% of Water

The SZ series recycles 2 gallons/minute and recovers up to 66% of the feed water, making this the most cost-effective and environmentally friendly freshwater system on the market.

Works with all Watermakers

The SZ Double Pass system is specifically designed to work with all on-board watermakers including our SeaXchange systems. Turn sea water to potable water then purify it for pure spot-free water that’s just 10 ppm of TDS or less!
