Installation and Maintenance Manual

RTAE-SVX001B-EN 9
General Information
Unit Description
The 150-300 ton Stealth™ units are helical-rotary type, air-
cooled liquid chillers designed for installation outdoors.
The compressor circuits are completely assembled,
hermetic packages that are factory-piped, wired, leak-
tested, dehydrated, and tested for proper control
operation before shipment.
Chilled water inlet and outlet openings are covered for
shipment.The Stealth featuresTrane’s exclusive Adaptive
Control ™ logic, which monitors the control variables that
govern the operation of the chiller unit. Adaptive Control
logic can adjust capacity variables to avoid chiller
shutdown when necessary, and keep producing chilled
water. All unit sizes are available with two independent
refrigerant circuits. A single refrigeration circuit option is
available for 150 and 165T units. Each compressor is
controlled by a variable speed Adaptive Frequency™
Drive Generation 3 (AFD
3
). Each refrigerant circuit is
provided with filter, sight glass, electronic expansion
valve, and charging valves.The shell-and-tube type
evaporator is manufactured in accordance with ASME
standards or other international codes. Each evaporator is
fully insulated and is equipped with water drain and vent
connection. As an option, a convenience outlet can be
supplied.
Units are shipped with full oil charge and can be ordered
with either a factory refrigerant charge, or optional
nitrogen charge.
