It is preferred in cases where the outdoor temperature (dry bulb) is insufficient for cooling.
It works on the principle of bringing the air temperature entering the device closer to the wet bulb temperature.
The automatic control mechanism prevents unnecessary water consumption by activating the spray system only when needed.
The amount of water loss is quite low compared to cooling towers.
