What are air cooled chillers?
Chillers are used to transfer undesired heat energy into the atmosphere during manufacturing and other industrial processes.
With air cooled chillers the waste heat is released into the air. This is why you see them sited on building roofs or in car parks, they need access to a lot of fresh air
As the heat is released into the air, there is no need for cooling towers, so air cooled chillers tend to have small footprints. It also means they can be used where there is insufficient water supply or water is an expensive amenity.
