MASTERKOOL is the outdoor cooling system designed for all outdoor areas or well-ventilated indoor areas.
MASTERKOOL provides effective cooling by the water evaporation principle, through which the heat is absorbed during water evaporation causing the air to become cool. Having utilised this principle, it sprays small water droplets into the air, which allows MASTERKOOL to enhance its ability to evaporate in a wider area without any form of condensation. The sprayed water droplets, as small as 5 microns are approximately 10 times smaller than the width of a human hair, and evaporate instantly; which is why it is called “Flash Evaporation”. The flash evaporation can reduce the surrounding air temperature by as much as 5 to 10 degree celsius. You’ll obtain cooling sensations in an environmentally friendly manner without getting wet.

Here is the theory behind installing the Masterkool cooling fans.
