Adiabatic cooling systems function similarly to dry cooling systems, but with the incorporation of pre-cooling pads; running water over pre-cooling pads and drawing air through the pads depresses the ambient dry bulb of the incoming air. The depressed dry bulb allows for greater system heat rejection.


The result of this is that adiabatic systems are highly effective in hot, dry environments, while using less water than traditional evaporative units. Adiabatic cooling units also deliver the required cooling capacity in a smaller footprint and/or lower fan motor horsepower than a completely dry cooler/condenser.

Adiabatic coolers work in much the same way as a dry cooler for most of the year, but they also come fitted with an adiabatic spray system that is the final stage of cooling that is only employed during the hottest times of the year.

 

This final stage of cooling works by water being sprayed into the air stream, as the air is drawn across the coil by the fans. The sprayed water evaporates into the air stream and thus cools the air before it passes over the coil and so enables a greater cooling effect on the coil. This enables the cooler to cool the media (generally a water/glycol solution) to within 5°C of the wet bulb ambient temperature. The water that is used for this is direct from the mains supply and is not recirculated like in a cooling tower.

 

Another benefit of using an adiabatic cooler over a dry air cooler is that due to the efficiencies of the adiabatic system, the unit is typically of a smaller footprint which can assist when space is at a premium. We can also provide the same cooler orientations and options as our dry air cooler range.
