Mist cooling system [mcs], pioneered by mist resonance engineering, is a revolutionary system for cooling large quantities of hot water making conventional spray system/cooling towers obsolete. It enhances the process output qualitatively as well as quantitatively and makes considerable savings on energy. It has been effectively used by various industries in india and abroad for the last 20 years. Salient features of mcs: ensures an approach of 0 to 1ºc to wet bulb temperature with a ?t of 12 to 15ºc; assured saving of 25-30% on energy; negligible maintenance; and payback period of 1 year. Applications of mcs: mcs has applications in industries like refineries/petrochemical plants; chemical industries; power plants/cogeneration units; steel plants; fertilizer plants; sugar industries; solvent extraction plants; and at all such locations where water cooling plays an important role in process.
