General Information
Unit Description
The CGAM units are scroll type, air-cooled, liquid chillers, designed for installation outdoors. The
20-35 ton units have a single independent refrigerant circuit, with two compressors per circuit. The
40 ton and larger units have 2 independent refrigerant circuits, with two compressors per circuit.
The CGAM units are packaged with an evaporator and condenser.
Note: Each CGAM unit is a completely assembled, hermetic -compressors packaged unit that is
factory-piped, wired, leak-tested, dehydrated, charged and tested for proper control
operations prior to shipment. The chilled water inlet and outlet openings are covered for
shipment.
The CGAM series features Trane's exclusive Adaptive Control logic with CH530 controls. It
monitors the control variables that govern the operation of the chiller unit. Adaptive Control logic
can correct these variables, when necessary, to optimize operational efficiencies, avoid chiller
shutdown, and keep producing chilled water.
Each refrigerant circuit is provided with filter, sight glass, electronic expansion valve, and charging
valves on the CGAM.
The evaporator is a brazed plate heat exchanger which is equipped with a water drain and vent
connections in the water piping.The condenser is an air-cooled slit fin coil.
The condensers are available in three configurations depending on the tonnage of the unit. Units
may be referred to the size by the condenser configuration. The three configurations are slant, V
and W.
