In addition to the many standard features of the 10 and 15-ton air cooled Cold Generator^® chiller, there are several added benefits which make selection, installation, and service easier.

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.

Weight Reduction

The weight of the 10 and 15-ton units has been reduced up to 27 percent in comparison to previous models. Less weight results in 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.

Serviceability

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..

Optional Features

• Hot Gas Bypass — Allows unit operation below the minimum step of unloading.
• Low Ambient Head Pressure Control — Modulates the rpm of the fan motor in response to outdoor ambient temperature and unit head pressure. Provides unit cooling operation down to outdoor temperatures of 0°F.
• Coil Guard — Metal grille with PVC coating to protect the condenser coil.
• Isolation — Neoprene in shear or spring flex isolators.
• Power Supply Monitor — Provides protection against phase loss, phase reversal, phase imbalance, incorrect phase sequence and low line voltage.
• Elapsed Time Meter/Number Starts Counter — Records number of compressor starts and operating hours.
• Flow Switch — Required as a safety interlock to prevent operation of unit without evaporator flow (available option for field installation only).
• Integrated Comfort™ Systems (ICS) Interface — Provides the ability to communicate with Trane Tracer ® or Tracker ® building management systems via a Thermostat Control Module — (TCM).
• Gauges — Monitor suction and discharge pressures.
