Service Description The Air2o multi-stage desert air conditioner is a water-based evaporative cooling system that cools air in hot and dry areas by bringing air into contact with water in two stages (indirect and direct). In the first stage, “indirect,” outside air (100% fresh air) is drawn in and passed through a cold water heat exchanger, resulting in the cooling of dry air without the air coming into contact with water and without adding moisture. Then, in the second, “direct” stage, the air produced from the first stage is passed over a medium saturated with water according to special specifications, so that the air comes out cooler and with an appropriate humidity level. Nafal Air Conditioning looks forward to meeting the needs of its clients across various project sectors. Therefore, we at Nafal install all types of air conditioning units within our clients' projects.
