Chemical Free Water Treatment for Cooling Towers, HVAC and Wastewater

State of the art CO2 friendly and durable solutions

At Elgressy and Aerialliftasia, we understand water treatment’s unique requirements and challenges. We understand the need for durability, sustainability, reliability, cost efficiency, and have developed our revolutionary systems in accordance. Our patented and innovative systems apply to the industrial, commercial and municipal sectors.

With patented and innovative electrochemistry, electrocoagulation and electro oxidation technology at its core, Elgressy developed groundbreaking, chemical-free water treatment solutions for industrial, commercial and municipal applications. Elgressy’s industrial-grade systems revolutionize water and wastewater treatment by providing simple, reliable, cost-effective systems and know-how.

Huge savings of energy & water
resulting in quick return on investment / ROI

Elgressy`s solution is based on a non-chemical, state of the art, patented technology which prevents scaling, bio-fouling, microorganism growth, inhibits corrosion and produces free oxidants in the water

Cooling Towers

Elgressy electrocoagulation and oxidation systems effciently separate and remove contaminants from water and wastewater, without using chemical additives or generating hazardous byproducts.

Waste Water

Elgressy`s solution facilitates the automatic control and eradication of microorganisms in hot water systems based on an elecro-chemical process which reduces significantly the sediment and scale within the hot water system.

Bacteria Eradication

Elgressy`s solution is based on an electrolytic technology that prevents scale deposition, reduces and removes chlorine and bacteria from the water and substantially reduces corrosion rates.

Heat Exchangers

Elgressy`s solution is based on electro-oxidation process which supplies a comprehensive treatment regime for a wide range of contaminating agents in one, unique package. Reduce Sludge Volume.

Contamination Removal

The technology both prevents corrosion and works to cure the affects of corrosion already present in the system and is effective in water tanks and all the pipes leading in and out of the system, whether galvanized, plastic or Copper

Water Tank Protection

Go green! Our mission and mutual task and
responsibility is to preserve this world
remember it is not Our world but
our childrens world.

Go Green Go Elgressy

How chemical-free water treatment supports LEED projects

LEED rewards buildings that use less water and fewer hazardous materials. Our Elgressy electrochemical systems for cooling towers, heat exchangers and wastewater help projects work toward both goals. There are no treatment chemicals to store, handle or discharge, scale and corrosion are reduced, and cooling water can often be run at higher cycles of concentration, which lowers make-up water use.

Every project and rating system is different, and LEED credits are awarded by the U.S. Green Building Council, not by equipment suppliers. Contact us to discuss how chemical-free water treatment can support the water efficiency and sustainability targets of your building. You can find the official rating systems at usgbc.org/leed.
