Product Catalog Air-Cooled Condensers — CAUJ 20-120 Tons August 2011 ACDS-PRC003-EN
Introduction Air-Cooled Condensers Built for Every Need Trane has the right condenser... If you are designing a new system or replacing an existing air-cooled condenser, Trane can satisfy virtually any application need. Whether coupled with an industrial compressor, a single zone commercial self-contained unit, compressor chiller or a Cold Generator® chiller, Trane has the right air-cooled condenser for the job.

Features and Benefits 20 to 120 Ton Units Trane 20 to 120 ton air-cooled condensers have an operating range of 40°F to 115°F, with a low ambient option down to 0°F. The control panel is factory-installed and wired to prevent potential damage and to provide weathertight protection. The control panel contains: • fan motor contactors. • fan cycling controls. • terminal point connection for compressor interlock. • 115-volt control power transformer.
Application Considerations Certain application constraints should be considered when sizing, selecting, and installing aircooled condensers. Unit and system reliability depends on properly and completely acknowledging these considerations. Consult your local Trane sales engineer if your application varies from these guidelines. Setting the Unit A base or foundation is not required if the selected unit location is level and strong enough to support the operating weight.
Application Considerations starvation and warm air recirculation, resulting in unit capacity and efficiency reductions, as well as possible excessive head pressures. The recommended lateral distances are listed in the Dimensional Data section. Voltage Nominal voltage is the nameplate rating voltage. The actual range of line voltages at which the equipment can satisfactorily operate is given below: Table 1.

Selection Procedures When manually matching condensers with compressors, performance cross plotting becomes necessary. The following procedure should be used to determine the correct condenser. 1. Determine the total cooling load. Make a prelimary compressor selection based on the expected evaporator SST and condensing temperature.

Mechanical Specifications General Factory-assembled and wired air cooled condensing unit. Units are constructed of 14-gauge welded galvanized steel frame with 14 and 16-gauge galvanized steel panels and access doors. Unit surface is phosphatized and finished with an air-dry paint. This air-dry paint finish is durable enough to withstand a 1000-consecutive-hour salt spray application in accordance with standard ASTM B117. Refrigeration Circuits and Control The 20 to 30 ton units are single circuit.
