Features and Benefits Trane offers state-of-the-art water cooled and remote Condenser scroll liquid chillers for a wide range of comfort and process-cooling chillers are complete, factory-assembled chillers that offer ease of installation with microprocessor controllers providing maximum operating compact chillers install easily and quickly into most building layouts, making them ideal choices for retrofit or new building designs.

4 Trane Liquid Chillers Water-cooled chillers are complete, factory-assembled liquid chillers for comfort or process- cooling have multiple scroll compressors. Available in 7 sizes ranging from 20 to 70 nominal tons. Compressor chiller version (CCAQ 20 to 70 tons) available for use with remote condensers. Factory assembled and charged, complete with all refrigerant piping and electrical wiring. CGWQ models are charged with refrigerant, CCAQ models with dry nitrogen. Units ship ready to install, need only electrical and water connections. All components mounted in a rugged, open frame for easy access. Dual refrigerant circuits with dual shell-and-tube condensers on CGWQ 40 to 70 ton models.

5 CGWQ 20 to 30 models are single circuit. Robust cleanable shell-and-tube condensers uniquely suited for open loop cooling tower applications. The powerful unit controller offers complete chiller control and provides a wealth of information and diagnostics. All units meet ASHRAE efficiency guidelines. Fast Deliveries When your project has a critical deadline,Trane can help. A wide range of major components are readily available so that your model can be shipped fast. Installation Single point power connection for simplified, fast field-wiring. The powerful unit controller provides complete chiller controls and interface to a variety of platforms, including BACnet IP and Modbus as standard.

6 LonTalk , Johnson N2 and BACnet MS/TP require an optional interface. Units are pre-charged with oil and refrigerant (CGWQ) from the factory which speeds installation. CCAQ units have the proper standard oil charge and a charge of dry nitrogen. Units are designed to fit thru standard doorways. Factory testing ensures first-time smooth operation on start-up, and reduces follow up costs. Service Trane 20 thru 70 ton scroll chillers are designed with service personnel in mind. Unit design allows replacement of all major components without complete unit teardown. All CGWQ units have mechanically cleanable shell-and-tube unit controller provides diagnostic capability and remote factory diagnostics to aid local and factory service personnel in analyzing problems.

7 Unanticipated down time is minimized. CGWQ-PRC001B-EN 5. Features and Benefits Single Source Responsibility Trane is a single source provider, allowing the customer to obtain all building comfort systems through one source. Added Value Expertise Trane has more than 100 years of experience engineered into their means a quality Product that works right the first time! Leading in Efficiency and Reliability with State-Of-The-Art Scroll Compressor Technology ASHRAE Standard - 2010. AllTrane chillers meet and exceed the efficiency levels mandated by ASHRAE Standard standard requires higher efficiencies than past technologies can deliver. In fact, energy efficiency is so paramount; the US Federal Government has adopted Standard Federal Executive Order mandates energy consuming devices procured must be in the top 25% of their class.

8 In the case of chillers, ASHRAE is the Product standard for measurement. Potential Risk Not only has ASHRAE been adopted by the US Federal Government, it's expected to be adopted domestically, if not globally, in the future. Make sure that your chillers, as well as your entire HVAC system, comply or you may be caught retrofitting your project with new equipment and paying extra design dollars if the code changes during construction. Efficiency The energy efficiency ofTrane scroll chillers results in energy costs lower than most other comparable chillers. Superior engineered efficiencies are obtained by combining advanced scroll compressor energy efficient features with up to date heat exchanger technology and state-of-the- art controls.

9 Here's How: Scroll compressor's positive displacement design Dual refrigerant circuits Multiple compressors 40 through 70 ton models Optimum system design Reduced friction No valves Advanced heat transfer surfaces Reliability Trane Scroll Chillers with many new improvements feature highly efficient and reliable scroll compressors. Here's How: Scroll compliance allows liquid and dirt to pass through without damaging compressor (liquid slugging resistant). Advanced microelectronics protect compressor and motor from typical electrical fault conditions. Years of laboratory testing have optimized compressor and chiller systems reliability. Water-cooled scroll chillers are factory tested.

10 6 CGWQ-PRC001B-EN . Application Consideration Product Selection Both CGWQ and CCAQ products are offered in 7 models each ranging in capacity from 20 to 70. nominal tons. See Table 3 and Table 4, p. 11 to select the model best suited for your application. Since actual unit capacity can vary significantly from nominal capacity , it is important to base your selection on the actual conditions. Selection of the correct model will require attention to the minimum, as well as the full load capacity required. Selection of the proper equipment is an important part of a successful installation. Equipment sized too large will cycle more frequently and as a potential result lead to poor temperature and humidity control, shortened equipment life and higher utility costs.
