CNK ADV & CNK KSV Series Dry and Adiabatic Cooler

General Features

Adiabatic coolers works in same basic with dry coolers. There is a water sprayer system which provides additional cooling to the system. If cooling process water to a lower temperature than the ambient temperature is required, pressured water spray system works to saturate the inlet air. In this manner temperature is reduced to below the ambient temperature. Flowing of cooled air onto coil provides to cool circulating water below ambient temperature. 

The water spray system provides additional cooling when necessary during the hottest summer days with thermostat controlled system. There is no water consumption at other times. 

For instance, if inlet air that has 35ᵒC dry bulb temperature and 24ᵒC wet bulb temperature (40% relative humidity) is saturated up to 90% relative humidity by using spray system, dry bulb temperature of inlet air is reduced to approximately 25ᵒC.

 Considering cooling performance and affordable price, the most appropriate material for tube of coil is copper. The quality of the copper used for the tubes is one of the important characteristics for determining the life of the dry cooler. Wall thickness of the copper tube is 0.7 mm.

Lamellar materials used for dry coolers is aluminum. Although the lamella thickness varies depends on usage, 0,14-0,15 mm would be appropriate. In most applications, epoxy coated aluminum are preferred to ensure longer life. FRP coated galvanized steel is used as a cladding material for dry cooler. Instead of using steel sheet, using FRP cladding provides protection from corrosive effects of the external environment. FRP cladding offers great advantage in facility that close to sea. Ratio of %25-%35 glycol water is added into water to take precautions against freezing in winter season. Dry Cooler design is done according to this mixture.
