About this file
This is a product specification document for an air-cooled scroll chiller being provided for Cannon AFB Building 4625. The document details a Trane CGAM-60 chiller with a nominal cooling capacity of 60 tons, sized for chiller replacement at the military facility's Lubbock sales office. The unit is a 460-volt, 3-phase system featuring 4 compressors across 2 circuits and operates with R-454B refrigerant in compliance with ETL safety standards.
The chiller delivers a cooling capacity of 60.56 tons with an efficiency rating of 11.51 EER (Btu/W-h) and an Integrated Part Load Value (IPLV) of 17.74 EER. The evaporator operates with standard cooling using water as the working fluid, with entering and leaving fluid temperatures of 54°F and 44°F respectively, and a design flow of 144.8 gpm. The condenser configuration includes 6 fans rated for wide ambient conditions up to 95°F. Electrical specifications include a total power draw of 63.11 kW with a single-point MCA of 138 amperes and MOP of 175 amperes. The unit incorporates a dual high-head pump system with variable speed drive control and a 7.5 hp pump motor, operating head pressure of 64.8 ft H2O, and dual expansion tanks with 5-gallon volumes. The chiller is AHRI-certified to standards 550/590 (I-P) and meets ASHRAE 90.1-2019 minimum efficiency requirements for LEED compliance. Physical dimensions are 153.4 inches long by 88.4 inches wide by 84.8 inches high, with an operating weight of 6,184 pounds.
