Chiller Description
Chiller Scope
This manual provides relevant data to properly operate,
maintain, and troubleshoot the Trane Packaged TACW
chiller. Operator and maintenance personnel must be a
qualified refrigeration technician and have a working
knowledge of high voltage systems, low voltage control
circuits, and components and functions.
Chiller Capacities
The Packaged TACW chillers utilize flooded shell and tube
evaporators and condensers. They are available from 110
to 600 tons.
These chillers consist of an evaporator, condenser, twin-
turbine centrifugal compressor(s), compressor controller,
and interconnecting refrigerant piping. The chiller requires
connection to the condenser and chilled water circuits, as
well as the main electrical supply and control wiring.
The thermal capacity of these units is dependent on the
leaving temperature of the chilled fluid, maintaining a
minimum flow of fluid through the evaporator and keeping
debris out of the system. In applications where it is desired
to operate with a lower flow rate or higher temperature,
consult the factory for recommendations.
Water quality must be monitored and maintained by a
water treatment professional familiar with the materials of
construction and operation of the equipment. The
equipment arrives fully charged with refrigerant. As
required under Federal regulations, installation, initial start-
up, and technical servicing should only be performed by
fully qualified personnel.
System Description
All Packaged TACW chillers are designed with a very small
approach to enhance the compressor performance
resulting in an outstanding IPLV rating. Chillers are
available in different configurations and with various
standard options including different compressor models to
customize these chillers to your specific applications.

constructed of heavy-gauge powder coated aluminum and
mounted on sand blasted welded structural steel base and
painted with two parts epoxy paint for weather protection.
