There are several ways to apply the evaporative cooling process:
- direct evaporative cooling
- indirect evaporative cooling
- indirect/direct evaporative cooling, also known as two-stage evaporative cooling
Below you will find a description of these three methods and read about the benefits of Oxycom's patented two-stage evaporative cooling.
Direct evaporative cooling
Direct evaporative cooling, also known as direct adiabatic cooling or wet bulb cooling, is called direct as there is direct contact between the water and the air stream. During the direct evaporative cooling process, water is evaporated directly into the air stream that needs to be cooled down. This type of evaporative cooling is the most widely used form worldwide.
Oxycom uses direct evaporative cooling in the PreCooll system, with which outside air is sucked through wetted Oxyvap® media, to cool down the incoming air and increase the efficiency of mechanical cooling installations. The Oxyvap® media contains the patented aluminum hydro chill fin technology reaching extreme efficiencies of 90 – 92 % while having the lowest possible pressure drop of around 40 Pa at 2m per second.
