MILWAUKEE — The York® brand of Johnson Controls, a manufacturer of air-cooled chillers with variable-speed drive compressors, announces the York YVFA Free-Cooling Chiller line expansion capacity range, now up to 500 tons.  

The York YVFA chillers deliver an exceptionally low operating cost and a small footprint. Johnson Controls uses an Annual Energy Cost (AEC) modeling tool to produce a customized report factoring all key variables – geographic location, building type, operating hours, utility costs, and local weather data. In most locations, a facility operating 24/7 with a constant cooling load can achieve an operating cost payback in as little as two years.

Performance of the chiller is assured by AHRI certification, among the first times it has been given to an air-cooled screw chiller with free cooling. For more information, visit
