Traditional refrigerant A/C

Evaporative Cooling

As ambient temperature rises, energy consumption increases, efficiency decreases

As ambient temperature rises, energy consumption remains constant, efficiency increases

Can guarantee a fixed temperature

Temperature dependant upon ambient conditions

Can only operate well in a closed environment

Needs to operate with ventilation, open environment

Recirculates approximately 80 ¨C 85% internal stale air

Operates with 100% fresh air, no recirculation

Dehydrates the atmosphere within the working environment

Slightly increases humidity level in the working environment

Does not filter any air, leaves dust, minerals and bacteria in the air-stream.

Some filtration of air, removes dust, minerals and bacteria from the air-stream
