Air cooled water chillers absorb heat from process water, and the heat is then transferred to the air around the chiller unit;

Air cooled water chillers are more suitable for common applications on smaller or medium installations where space constraints may exist;

Water chiller machines are the most practical choice in places where water is scarce(such as desert areas);

Since the wet surface transfers heat better than the dry surface, it consumes about 10% more electricity than a water cooler chiller unit.
