evap cooler

Fresh outdoor air is drawn by a high-efficiency fan through suitable filters and passed over the large surface area of a cooling coil, which carries primary coolant being cooled through a Sensible Heat Rejection Unit, working in a heat-removal mode. Thereby, it cools the incoming air during summer from the ambient dry air of 42-44°C to 30-32°C without directly adding any water vapor to the incoming air.
