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 featuresTrane'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.
