Air coolers are extensively used cooling equipment in petroleum refining, chemical, metallurgical, and power plant industries for cooling various process media. Compared to other cooling systems, air coolers utilize ambient air as the cooling source, delivering significant energy and water savings.
?Dry air coolers can cool media to 20°C above ambient temperature
? Wet surface air coolers and evaporative air coolers can cool media to temperatures close to the ambient wet-bulb temperature, serving as alternatives to water coolers.
