The Free Cool atmospheric water generator is a device that extracts water from humid ambient air. Water vapour in the air is condensed by cooling the air below its dew point, exposing the air to desiccants, or pressurizing the air. Unlike a dehumidi?er, an AWG is designed to render the water potable. AWGs are useful where pure drinking water is dif?cult or impossible to obtain, because there is always a small amount of water in the air that can be extracted.
The extraction of atmospheric water may not be completely free of cost, because signi?cant input of energy is required to drive some AWG processes. Certain traditional AWG methods are completely passive, relying on natural temperature differences, and requiring no external energy source. Research has also developed AWG technologies to produce useful yields of water at a reduced energy cost. Free Cool AWG can produce Up to 10000 litters per day.
