More efficient with supreme performance
Chilled Water Systems
YORK® has the widest variety of water cooled chillers on the market that stand up to the demands of industrial and commercial applications.
Advantages of Water-Cooled Chillers
Chilled water systems use large quantities of water, which are housed in cooling towers. Large commercial chillers are usually water-cooled because they reach higher capacities with more efficiency. Additionally, commercial water cooled chillers are typically located inside of a building, so they tend to be better maintained because they’re more easily accessible.
