SYSTEM CGAP/H 50Hz Air-Cooled Chillers Introducing the Trane VWV system (Variable Water Volume)....... More for less indoor multi-system
Footprint...... We consider your space just as precious. Central to design of any project is the operating envelope of the air-cooler packaged chiller. Trane CGAP/H air-cooled chillers have a compact footprint to make the most efficient use of this available installation space.
Trane’s time-tested reliable chilled water system offers comfort, reliability and flexibility , all at the same time. Very few other systems do. Here is why ..........
Brazed plate heat exchanger with integrated distributor
With brazed corrugated stainless steel plates, this compact heat exchanger offers a highly efficient heat transfer rate that is less susceptible to erosion and corrosion while maintaining a homogeneous refrigerant distribution.
TRANE MICROPROCESSOR CONTROLS The brains behind the chiller are based on a PID state of the art microprocessor that allows diagnostics and remote alarm, while fully protecting the chiller from operational problems. Capabilities of the controller includes processing, monitoring, and diagnostics to ensure effective control over compressor

REFRIGERATION SYSTEM
Serviceability...... Something which we never miss
Reliability .....Built into the heart of the machine The compressors used are proven world class hermetically sealed compressors. Scroll compressors used on these chillers, are among the industries, most resilient and efficient compressors. The technology ...... From the legendary Trane chiller stable control Complete factory - wired with necessary capacity and safety controls. Enclosed in a weather-tight control panel with knockouts for jobsite installed wiring to ensure smooth and trouble - free installation and operation.
The control panel and unit panels are completely removable for service accessibility and convenience “ Rapid access” clips and Allen key arrangement allows fast access to the major components in the unit. Installation......Designed for your convenience The unit arrives at jobsites fully assembled tested, charged and ready to provide chilled water. No messy field assembly or refrigerant charging is required. Further, the unit has been designed for single power and water connection.
staging, resulting in efficient and accurate chiller operation. A higher end Trane microprocessor version is available that allows communication with detailed water, refrigerant pressures and electrical amp realtime readouts, and for more complex chiller applications.
