General Information
Unit Description
Ascend
™
Model ACS units are scroll type, air-cooled,
liquid chillers, designed for installation outdoors. Each
unit has two independent refrigerant circuits, with two
or three compressors per circuit. The chillers are
packaged with an evaporator and condenser.

otte
e:: Each 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 chiller features Tracer
®
UC800 controls to monitor
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. The evaporator is a brazed
plate heat exchanger equipped with water drain and
vent connections in the water piping. The condenser is
an air-cooled slit or serpentine fin coil, arranged in a
transverse V layout.
