General Information
Unit Description
The Ascend ™ ACR units are helical-rotary type, air-
cooled chillers designed for outdoor installation. The
refrigerant circuits are factory-piped, leak tested and
dehydrated. Every unit is electrically tested for proper
control operation before shipment.
Chilled water inlet and outlet openings are covered for
shipment. The chiller features Trane’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. The units feature two
independent refrigerant circuits. Each circuit utilizes at
least one compressor driven by an Adaptive Frequency
Drive. Each refrigerant circuit is provided with filter,
sight glass, electronic expansion valve, and charging
valves. The shell-and-tube evaporator is manufactured
in accordance with the ASME standards or other
international codes. Each evaporator is fully insulated
and equipped with water drain and vent connections.
Units are shipped with full oil charge and can be
ordered with either a factory refrigerant charge, or
optional nitrogen charge.
