Chemical-free water treatments

A pure and simple solution free of chemical products that uses proven technology for unequalled control of scale, corrosion and bacterial proliferation.

The new priority for cooling tower managers and owners

Why use a chemical-free treatment for your cooling tower

  • Increase the energy efficiency of your cooling towers
  • Reduce your operating costs
  • Comply with RBQ regulations
  • Eliminates corrosion
  • And many other advantages

There is a simple, powerful and ecological solution. The chemical-free WAVETM water treatment system for your cooling towers reduces operating costs and improves water management, as well as significantly shrinks your ecological footprint and helps you earn valuable LEED points.

Clean, proven technology

By opting for a 100% clean treatment through encapsulation and electromagnetic pulsation, you can effectively control microbiological activity, limit corrosion and thus eliminate the risks associated with the presence of legionella in your equipment. When encapsulated in a harmless light powder and/or damaged by electric shock, bacteria cannot reproduce, and its lifespan is reduced to a maximum of 48 hours.

In addition, the water in your cooling towers, like all drinking water, contains minerals such as calcium carbonate and magnesium, more commonly known as “limestone”. Constantly in contact with this limestone-laden water, the metal components in your cooling towers are prone to iron and/or copper oxide formation, which attacks the surfaces and can lead to corrosion. Whether uniform or localized, corrosion inevitably causes the system to deteriorate.

To increase the anticorrosive properties of your equipment and to prolong its life, electromagnetic pulsation technology (EMP) saturates the calcium carbonate found in the water, thus forming a very powerful 100% natural corrosion inhibitor. Your system is also protected from any localized corrosive attack caused by microbes or chemicals.
