Evaporative Condenser inStainless Steel

INFO

The best solution in evaporative cooling is now even more efficient and sustainable!

ECOSS G3: The best solution in evaporative cooling even more efficient and sustainable!The evaporative condenser in stainless steel: ECOSS, is a consolidated concept in the world market that demonstrates our ecological commitment with the environment and the concern about offering the industry an exclusive and highly efficient solution. It gives us the possibility of offering more than a product, a solution that exceeds the expectations of owners, operators and fitters of these units.

The alignment of our clients’ needs with a high quality and extremely reliable product, with stricter environmental requirements, make the evaporative condensers with galvanized coating become more and more obsolete due to the environmental emissions and the use of aggressive chemicals either at the galvanization process or at water treatment systems.

This way, the team who are responsible for the installations must consider the restrictions on the availability and quality of water, the control parameters and chemicals legislations before making the investment decision.

The concept of the evaporative condenser in stainless steel, ECOSS, facilitates these decisions. Since coils, casing, tray and structural parts are manufactured with 100% stainless steel, the harmful hot-dip galvanizing process is eliminated, as well as zinc or lead contamination on industrial waters, elimination of passivation treatments, free of white rust and reduction on water and chemicals consumption due to the high resistance of stainless steel.

The new generation of this stainless steel equipment, ECOSS G3, keeps the concepts of lower operational costs, lower maintenance costs, easy installation, accessibility, reliable performance, durability, and it presents an evaporative cooling solution developed with state-of-the-art efficiency and sustainability.
