There is a high quality Air Cooled Chiller Plant offered by us that consists of an air-cooled chiller, located outside of the building; primary and secondary pumps; expansion tank; air separator; and some form of chemical treatment. The pumps are arranged in a primary/secondary arrangement or in a variable primary pump arrangement. The chillers are refrigeration systems used in both commercial and industrial facilities to cool fluids and/or dehumidify air. They are used in a wide variety of settings including hotels, corporate events, restaurants, sporting events, large-scale construction, industrial and manufacturing plants, and so forth. The Air Cooled Chiller Plant is very useful.
