The project is located at Eglin AFB, Building 42. Work involves the replacement of two existing 650-ton chiller units and three existing cooling towers, including re-piping, re-working concrete pad(s), re-working electrical and conduit, and controls as needed. In addition, work involves the testing and commissioning of the new equipment. The new water-cooled chillers need to meet existing requirements or exceed them.
