ECOSS was developed for cooling solutions in the energy and process cooling sector as well as industrial refrigeration and HVAC applications. The concept is exactly adjusted to these sector requirements and presents an elaborate solution for prevalent challenges like water quality, passivation, and oxidation. Self-passivating stainless steel obviates oxidation and provides a significantly longer product life than galvanized steel. It survives quality upset conditions, and the fans and drives are designed for evaporative service. There is a five-year leak-free guarantee on the coils and the fully welded, stainless steel, cold water basin. The units are delivered as a separate coil section and basin. The modular frame design with high torsional stiffness ensures the sections remain perfectly intact during transportation.
