Features and
Benefits
The 10 and 15-ton air-cooled Cold
Generator
™ chillers, with Trane direct
drive hermetic scroll compressors, has
outstanding standard features and
additional benefits that make selection,
installation, and servicing easy.
Flexibility
Footprint
Central to the design of any project is the
operating envelope of the air-cooled
packaged chiller. With this in mind, Trane
builds the chillers to make the most
efficient use of the available installation
space. The Trane CGA model chillers are
extremely compact. They have the
lightest weight, the smallest footprint,
and the lowest silhouette of any chiller in
the industry.
Less Weight
These lightweight models afford less
stress on building supports and greater
handling ease.
Installation
Installation time and effort are reduced
when dealing with a significantly smaller
and lighter unit. In addition, having
electrical and water connections on the
same side of the unit and a single-point
main power connection serves to make
installation easier. The unit arrives at the
jobsite fully assembled, tested, charged
and ready to provide chilled water.
Ease of Service
The control panel and unit panels are
completely removable for service
accessibility and convenience.
ICS Interface
Communication with Trane Tracer ™ or
Tracker ™ is possible through the ICS
Interface on the 10 and 15 ton Cold
Generator chiller.
