Features and Benefits Reliability • Years of laboratory testing, including running the chiller at extreme operating conditions, have resulted in optimized compressor and chiller systems reliability by confirming a robust design and verifying quality each step of the way. • Direct-drive, low-speed scroll compressors with fewer moving parts provide maximum efficiency, high reliability, and low maintenance requirements. Suction gas-cooled motor stays at a uniformly low temperature for long motor life.
Features and Benefits Simple, Economical Installation • Standard sound levels are roughly 5-8 dBa less than the previousTrane air-cooled models, perfect for applying outdoor HVAC equipment in neighborhoods, such as K-12 schools. • System integration available with LonTalk® or BACnet® through a single twisted-pair wire for a less expensive translation to an existing building automation system.
Application Considerations Certain application constraints should be considered when sizing, selecting and installingTrane CGAM chillers. Unit and system reliability is often dependent upon proper and complete compliance with these considerations.Where the application varies from the guidelines presented, it should be reviewed with your localTrane account manager. Note: The terms water and solution are used interchangeably in the following paragraphs.
Application Considerations Water Flow Limits The minimum water flow rates are given in the General Data section of this catalog. Evaporator flow rates below the tabulated values will result in laminar flow causing freeze-up problems, scaling, stratification and poor control.The maximum evaporator water flow rate is also given. Flow rates exceeding those listed may result in very high pressure drop across the evaporator.
Application Considerations Water Temperature Leaving Water Temperature Limits Trane CGAM chillers have three distinct leaving water categories: • standard, with a leaving solution range of 42 to 65°F (5.5 to 18°C) • low temperature process cooling, with leaving solution range of 10 to 65°F (-12 to 18°C) • ice-making, with leaving solution range of 20 to 65°F (-7 to 18°C) Since leaving solution temperature below 42°F (5.
Application Considerations microcomputer’s ability to maintain an acceptable supply water temperature range. Furthermore, full load temperature drops of less than 6°F (3.3°C) may result in inadequate refrigerant superheat which is critical to long term efficient and reliable operation. Sufficient superheat is always a primary concern in any refrigerant system and is especially important in a packaged chiller where the evaporator is closely coupled to the compressor.
Application Considerations Another advantage of an ice storage system is its ability to eliminate chiller over sizing. A “rightsized” chiller plant with ice storage operates more efficiently with smaller support equipment while lowering the connected load and reducing operating costs. Best of all this system still provides a capacity safety factor and redundancy by building it into the ice storage capacity for practically no cost compared to over sized systems.
Application Considerations Isolation and Sound Emission Structurally transmitted sound can be reduced by elastomeric vibration eliminators. Elastomeric isolators are generally effective in reducing vibratory noise generated by compressors, and therefore, are recommended for sound sensitive installations. An acoustical engineer should always be consulted on critical applications. Figure 3. Installation example Piping isolation Chilled water piping should be supported.
Application Considerations Unit Location General Unobstructed flow of condenser air is essential to maintain chiller capacity and operating efficiency. When determining unit placement, careful consideration must be given to assure a sufficient flow of air across the condenser heat transfer surface.Two detrimental conditions are possible and must be avoided: warm air recirculation and coil starvation.

Controls LCD Touch-Screen Display with Multi-Language Support The standard DynaView display provided with theTrane CH530 control panel features an LCD touch-screen that is navigated by file tabs.This is an advanced interface that allows the user to access any important information concerning setpoints, active temperatures, modes, electrical data, pressure, and diagnostics. It uses full text display available in 19 languages.
Controls Stand-Alone Controls Single chillers installed in applications without a building management system is simple to install and control: only a remote auto/stop for scheduling is required for unit operation. Signals from the chilled-water pump contactor auxiliary, or a flow switch, are wired to the chilled-water flow interlock. Signals from a time clock or some other remote device are wired to the external auto/stop input. • Auto/Stop - A job-site provided contact closure turns the unit on and off.
Controls BACnet Interface BACnet® interface capabilities are available, with communication link via single twisted-pair wiring to a factory-installed and tested communication board. Required features: • BACnet Interface (selectable option with chiller) BACnet is a data communication protocol for building automation and control networks developed by American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).
Controls Tracer SC TheTracer SC system controller acts as the central coordinator for all individual equipment devices on aTracer building automation system.TheTracer SC scans all unit controllers to update information and coordinate building control, including building subsystems such as VAV and chiller water systems. With this system option, the full breadth ofTrane’s HVAC and controls experience are applied to offer solutions to many facility issues.

Mechanical Specifications General Units are constructed of galvanized steel frame with galvanized steel panels and access doors. Component surfaces are finished with a powder-coated paint. Each unit ships with full operating charges of refrigerant and oil. Compressor and Motor The unit is equipped with two or more hermetic, direct-drive, 3600 rpm 60 Hz (3000 rpm 50 Hz) suction gas-cooled scroll compressors.
Mechanical Specifications Capacity modulation is achieved by turning compressors on and off. The 20-35 ton units have two capacity stages. The 40-120 ton units have four capacity stages.The 130 ton unit has six capacity stages. Unit Controls (Trane CH530) The microprocessor-based control panel is factory-installed and factory-tested.The control system is powered by a pre-wired control power transformer, and will turn on and off compressors to meet the load.
Mechanical Specifications • LonTalk® LCI-C (interface optional; control source not supplied) • BACNet® (interface optional; control source not supplied) • TraneTracer Summit™ system (interface optional; control source not supplied) Quality Assurance The quality management system applied byTrane has been subject to independent third-party assessment and approval to ISO 9001-2008.
Mechanical Specifications necessary with short water loops. A high circuit inertia reduces the compressor’s cycling to increase the compressor life span and allow for more precise water temperature accuracy. It also saves energy as compared to hot gas bypass.
Mechanical Specifications Half Louvers Louvered panels cover the condenser coil only. Available on the 80-130 ton units only. Comprehensive Acoustic Package This option includes acoustical treatment for compressor. Condenser Coil - CompleteCoat Condenser coils are made of aluminum fins (plate fins) mechanically bonded to internally finned copper tubes.The condenser box is then submerged in an epoxy polymer bath where an electrostatic charge is used to uniformly deposit the epoxy onto the coil.
