Description
Dry coolers are systems that cool process water with ambient air. Dry coolers can cool down the ambient temperature up to 5°C. In wet/adabatic coolers, atmospheric air is brought into contact with water to increase humidity. After saturating with moisture, the air's temperature decreases. This allows for cooling with water at lower temperatures.
Dry coolers are preferred in regions with high temperatures, as they consume very little water compared to open or hybrid cooling towers. Additionally, dry coolers operate in a closed-loop cooling water circuit, which prevents them from coming into contact with dirty air. Consequently, maintenance and cleaning costs are low.
One of the primary applications of dry coolers is in free cooling systems. By connecting them in series with cooling unit devices, they can reduce the workload of the cooling unit during periods of low ambient temperatures, leading to significant electricity savings.
