The HardWaterWizard CW-4 Commercial Water Conditioner is an excellent choice for those who want soft water but don't want the salt contamination or maintenance effort and expense of ion exchange softeners. Model CW-4 is for pipes up to 4-inches in diameter.

The HardWaterWizard™ is a great way to soften or condition your water up to 125 grains. The HardWaterWizard requires less than 20-watts of electricity, will work on plastic, copper, or steel pipes, and comes with a 2-year warranty.

The HardWaterWizard™ is easy to install and requires no plumbing or maintenance. It's safe and low-cost operation requires less than 20 watts of power. Easy to install, it's an excellent choice for those who want to keep scale away but don't want the salt contamination or the maintenance and expense of ion exchange softeners. In addition, many municipalities are outlawing ion-exchange water softeners.

The HardWaterWizard Commercial Water Conditioners are excellent for Gas-fired and Electric Boilers, Cooling Towers, Commercial Icemakers, Decorative Fountains, Evaporative Coolers, Commercial Laundries, Hotels and Motels, Crop Irrigation Water, Plastic Injection Molding, Hydroponics, and much, much more!

How does the HardWaterWizard™ Electronic Water Softener Work?

How the CS-4 HardWaterWizard Electronic Water Softener Works

The signal cable is wrapped externally around the pipe. The HardWaterWizard produces an oscillating electrical field inside the water pipe alternating at 1,000 to 12,000 cycles/sec. The complex modulated signal field at variable frequency induces an electrical field in the pipe which alters the hard water ions and increases their solubility. The continuously changing frequency alters the property of the hard water molecules by changing them to soft crystals. This also increases their solubility. The water becomes less saturated with calcium and is able to dissolve existing scale.

Benefits of the HardWaterWizard™ Electronic Water Conditioner

Before and After HardWaterWizard Scale Reducer
  • Reduces scale - Keeps hard water deposits from forming
  • Removes existing scale in 90 days
  • Treats water up to 120 grains*
  • Increases water heater efficiency
  • Reduces soap & detergent use
  • Eliminates scale buildup on electric heating elements
  • Reduces calcium spotting and soap usage in bottle cleaning
  • No Maintenance - easy to install & operate
  • No plumbing or special skills needed
  • No salt or chemicals used
  • 2 Year Limited Warranty
    * with proper model and application

Extensive tests and evaluations on the patented technology have been reported in the ASHRAE Journal in 2003. Tests at Vertex confirm the same formation of rounded amorphous crystals in the treated water. In addition, there is a reduction in ph of 0.1 to 0.3 in the treated water. This leads to the elimination of any existing scale. Tests show that 10-grain hardness treated water will use 5% less soap than untreated water.
