Mist Affan are an edge above the traditional coolers in terms of strength, aesthetics, portability and of course functionality! Traditional coolers use "Khas" as a filter; while these use replaceable evaporative pads. Further, these operate on 100% fresh air, no re circulation!
These are best applicable in ventilated open areas such as industrial workshops, large banquets, hospitals, warehouses etc.
High-Pressure Misting Systems will work very effectively in both low and high levels of humidity. Even when the humidity exceeds 90%, the effects of the High-Pressure Misting System will be felt with the rapid drop in temperature and make you feel cool and more comfortable.
Flash evaporation occurs when water is forced through micro nozzles, creating a super fine mist. The smaller each water droplet, the more surface area per gallon of water and the more effectively the water evaporates. As the super-fine water droplets are introduced into the atmosphere, they quickly absorb the heat present in the environment and evaporate, hence the air is cooled.
High-Pressure Misting Systems operate between 800 and 1200 psi (pounds per square inch) of water pressure. A High- Pressure Pump is the heart of the misting system and is utilized to increase the pressure of the water flow. Droplets of water the size of 10 microns or smaller are forced through an air stream. As the micron water droplets “flash evaporate” they pick up heat from the air, which significantly drops the temperature between 25 and 35 degrees Fahrenheit, without making you wet.
