In adiabatic cooling pad systems, cool pads are placed in special sheet metal assemblies which are mounted in front of fin block. With the aid of the pump, water wets the pads from the upper part of the pad system. The outside air, which is dry and hot, is pre-cooled by passing it through wet cooling pads. The temperature of the air that contact with the wet cooling pads is approximated to the wet thermometer temperature. The water does not contact directly with the fins. Thus fins lifetime is longer than the direct spraying systems. Also pads prevent contamination of fins. Since the microorganisms, minerals and similar parts do not mix into the air during the evaporation phase of water, the working principle is completely healthy. The system ensures that product efficiency can be increased with minimum water consumption.
