ECOSS G3: The Best Solution in Evaporative Cooling with enhance efficiency and durability

The Güntner ECOSS stainless steel evaporative condenser product line is proof of our ecological commitment to environmental and industry concerns that and enables us to offer a product that will exceed the expectations of the facility owners, operators, and installers.

Galvanized coatings for evaporative condensers have been used in industry since the 1950s. A lot has changed since the 1950s. More stringent environmental discharge concerns have led to the reduction or elimination of effective chemicals in both the galvanizing process and in water treatment programs. Facility owners need to consider water usage restrictions, source water quality, discharge permits, and which chemicals they are willing to allow at their prospective facility site prior to making any investment decision. The ECOSS stainless steel evaporative condenser product line makes these decisions a lot easier. Stainless steel coils and casing do not leach zinc or lead into the water system, do not require costly and time consuming passivation treatments, and do not risk the occurrence of premature failure due to “white rust”. They do offer superior corrosion resistance to reduce water and chemical usage, a reduced propensity to scale on the smooth walled stainless steel, and a more forgiving material for long life even when faced with eventual water quality “upset conditions.”

The ECOSS solution addresses the environmental and economic impacts of strained water resources. This eco-friendly control technology minimizes water treatment requirements and allows for operation at higher cycles of concentration, with reduced blowdown and lower make-up water requirements.

Güntner expertise in heat transfer design and stainless steel construction allows us to provide these benefits in a cost effective manner which boosts the return on investment for all-stainless construction to unprecedented levels. The total cost of ownership is reduced through long equipment life, low operating costs, low maintenance costs, and sustainable thermal performance, making the ECOSS stainless steel evaporative condenser the new choice in evaporative cooling.

Made of 100% stainless steel, the ECOSS G3 maintains the concepts of lower operating costs, lower maintenance costs with high performance reliability and durability.This State-of-the-Art Cooling technology offers anefficient and sustainable solution to your needs.

The quality of galvanizing processes has declined in the last decades because of chrome and zinc have been virtually eliminated due to environmental impact and costs of such material. The replacement to aluminium and other materials do not offer the same protection efficiency and corrosion protection as per galvanized steel. With the ECOSS solution, all coils, fairings, tray and structural parts are manufactured with 100% stainless steel eliminating the need for galvanisation. The smooth coil surface also allows the application of chemical cleaning agents to allow recovery of the coil to it’s pristine condition. The ECOSS product comes with greater durability and thermal efficiency over time.

Significantly Reduced Installation Labor

The EC fan option includes factory wiring, plug-and-play control which offers quick and trouble-free assembly of sections, this in turn reduces installation labor and site construction time. The upper and lower sections fit tightly together with an inter-locking structural design which ensures proper alignment and prevents water leakage at the field seams. The robust modular frame ensures the sections remain square during transportation and allow for trouble-free alignment during assembly, reducing man hours and access requirements associated with assembly. The integral positioning guide points and field seam design do not require drift pins or sealer tape for proper, quick, and watertight assembly.
