Aqua-Rex Water Conditioning Solutions:
Detailed Case Studies and Benefits

Aqua-Rex is excellent for your home as an effective alternative to the traditional water softener, but it is also used in many of the major properties in Las Vegas.

In the realm of commercial property management, the quest for efficient, cost-effective, and sustainable water treatment solutions is relentless. The need to balance operational efficiency with environmental stewardship and cost containment is a challenge that property managers constantly navigate. Enter Aqua-Rex, a groundbreaking water conditioning technology designed to meet the unique needs of large-scale properties seeking superior water-softening alternatives.

Commercial properties, from towering high-rises to expansive hotel complexes and sprawling educational campuses, require a water treatment system that not only performs with unwavering reliability but also aligns with the increasing demands for green building practices. Aqua-Rex delivers on all fronts, offering a scientifically proven solution that drastically reduces scale buildup without the hefty environmental footprint or the ongoing expense of traditional water softeners.

Gone are the days of frequent maintenance, cumbersome salt bag replacements, and the hassle of regulatory compliance related to salt discharge. Aqua-Rex stands as a testament to innovation in water conditioning, with its non-intrusive installation and a mechanism that operates on ultra-high frequency radio waves, fundamentally changing how minerals behave in water systems, thus preventing the hard scaling that is all too common in commercial settings.

Whether you manage a luxury hotel, a high-traffic convention center, or a large-scale industrial facility, Aqua-Rex offers an unparalleled solution that ensures your operations run smoothly, your maintenance costs are significantly reduced, and your commitment to sustainability is clearly demonstrated. It’s time to embrace a new standard in water treatment—a standard where Aqua-Rex leads the way for commercial properties ready to step into the future of water conditioning.

The Cosmopolitan Hotel was constructed without any water softeners except in the dishwasher kitchens. After some earlier trials, Aqua-Rex units were supplied in August 2012 to be installed on the plate and frame heat exchangers supplying hot water to both towers and the low rise. Subsequently, additional units were installed on the recirculation loops in the towers, following which it was found that scale could be brushed away from the worktops around the faucets, leaving them completely scale-free. The total installed cost of all the units was less than $100,000. No issues caused by scaling have occurred on the property in the areas treated by Aqua-Rex since they were installed. This contrasts with similar properties nearby where scale issues have been a constant problem.

The Cosmopolitan Hotel and Casino continues to use Aqua-Rex throughout the property, treating the water supply for the suites, the Restaurants, and the Casino Restrooms. Using conventional softeners would have used up a huge amount of the precious space on this site, so Aqua-Rex was not only the most practical solution, but it also saved them a massive amount of money as well. 

How Aqua-Rex Innovates Water Softening

Technology Notation: Contrary to traditional methods, Aqua-Rex employs a specialized radio transmitter that directly interacts with iron molecules in water, preventing scale formation.

Operational Mechanism: Utilizing ultra-high frequency radio waves, Aqua-Rex modifies the crystalline structure of minerals that cause scaling, transforming them into non-adherent particles.


  • Significantly diminishes scale deposits, ensuring cleaner plumbing fixtures and appliances.
  • Transforms existing scale into a cleanable form, simplifying maintenance.
  • Installation is a breeze, requiring no plumbing alterations or interruptions to the existing water system.

Aqua-Rex Frequently Asked Questions

Aqua-Rex is the only device of its type with US independent third-party performance verification. When tested by IAPMO R&T Labs it showed it could reduce scaling by 83% in Las Vegas water heated to 180°F for 23 hours.

Aqua-Rex is simple to install. Just wrap the wires around the inlet pipe to the water heater. Second choice would be on the softener loop or third choice anywhere else on the cold-water supply. Remember the signal goes in both directions, upstream and downstream so you don’t need to pass the water through the wires to have it treated. Just plug the transformer into an outlet – that is all you have to do. No set up or calibrating and it needs no servicing, supplies or maintenance, it is Plug and Play. It cost around $20 a year in electricity. There are no pipes to cut or plumbing to play with so it’s perfect if you are a Renter. Just remember to take it with you when you move home.

Aqua-Rex treats all the water in the home, all the time. It sends a signal into the water heater even when no water is flowing, and it also sends a signal back into the cold supply in the rest of the home so mixing valves, showerheads and kitchen faucets won’t get scaled up either. It is OK to treat the water to the kitchen faucet because it doesn’t add unhealthy sodium to the water, instead it retains the healthy calcium.

Aqua-Rex doesn’t use any salt or chemicals and it doesn’t produce any environmentally unfriendly discharges. It needs no maintenance or servicing and it costs hardly anything to run. It doesn’t add any unpleasant taste to the water or risk any additional corrosion to your plumbing system. It’s a lot less expensive to buy, install and maintain.

Aqua-Rex reduces scaling like a softener, but it also gets rid of the old scale in the home which a softener won’t do. It softens hot water, so you use less soap and detergents, but you don’t get that slippery feel to the water from the sodium dumped in by a softener. It can deliver about the same benefits as a conventional water softener, and there’s no salt to haul!

You can wrap the Aqua-Rex wires on any type of pipe material: plastic or metal, even the flexible copper inlet pipe to the water heater.

Aqua-Rex is great for clearing the calcium scale from tiles and water features. It reduces scaling in the saltwater chlorine generator and makes the biocide work more efficiently. It reduces phosphates thus making the pool clearer. The WK1P is fully waterproof and should be installed on the circulating line after the pump. Ask for Aqua-Rex in your local pool store or see the equivalent Jacuzzi de-scaler in your local Leslie’s Pool Supplies.

The answer is no! The pump in the dishwasher reduces the effectiveness of Aqua-Rex so you need to use a good hard water detergent and most importantly a hard water rinse aid, such as Lemi Shine ®, which is available from most stores. If you follow these instructions you should be happy with the results from the dishwasher. Laundry washing machines work better with Aqua-Rex.

Aqua-Rex units are available for all pipe sizes and are installed on hotels, condos, industrial plants and cooling towers. They are used in schools, colleges and military bases, everywhere that hard water is a problem.

“It doesn’t make sense to pollute the little water there is with salt, when Aqua-Rex can do much the same job as a water softener – and for a lot less money!”
