Dry coolers are a natural supplement to our pogram of our modular cooling towers and are used in many different environments that require a closed cooling circuit and can be supplied as ‘V’ shaped or frame mounted horizontal coolers. Dry air coolers are an alternative to traditional evaporative cooling towers and involve significantly lower maintenance and Legionella risk.
In cooling towers the water cooling occurs through the evaporative process allowing the water to be cooled below the wet bulb temperature. However in a dry cooler there is a finned tube wall between water and air and cooling of the water is made by heating up the air. In this case the air temperature is the lower cooling limit.
