Evaporative cooling: the green alternative to traditional cooling
Evaporative cooling is a simple and easy method of cooling that has been used throughout our history. As early as two thousand and five hundred years ago, the Egyptians used wet curtains made of Phragmites to cool down the air. The cooling effect is achieved when water in the medium absorbs heat from the air as it passes through. The same effect can be felt after rain. The ambient air can drop several degrees because the rain droplets absorb the heat from the surrounding air.
Evaporative cooling is the green alternative to traditional air conditioning. It consumes up to 80% less energy and requires significantly lower initial investment, installation and maintenance cost. It also uses natural water as a cooling agent instead of refrigerants that pollute the environment.

The evaporative cooling system does not use refrigerants or compressors. Instead, it delivers cooling by combining water evaporation with air movement through a specially designed evaporative pad. The water is pumped from the tank and distributed over the pad to form a water screen through which the air is cooled.
Another method of evaporative cooling is by forcing water, by means of a high-pressure pump, through specially designed misting nozzles. This creates a fog of ultra-fine water droplets with an average size of less than 10 microns. These tiny water droplets quickly absorb the energy (heat) present in the environment and evaporate, becoming water vapor (gas). The energy (heat) used to change the water to gas is eliminated from the environment, hence the air is cooled.
