Features and Benefits Trane 3-D Scroll Compressor Simple Design with 70% Fewer Parts Fewer parts than an equal capacity reciprocating compressor means significant reliability and efficiency benefits. The single orbiting scroll eliminates the need for pistons, connecting rods, wrist pins and valves. Fewer parts lead to increased reliability. Fewer moving parts, less rotating mass and less internal friction means greater efficiency than reciprocating compressors.
Features and Benefits Coil Frost Protection Trane offers Frostat™ with the VAV system control option on the 20 to 120-ton units. FROSTAT is the industry’s most reliable method of coil frost protection and assures that your system will provide energy efficient comfort at part load conditions. Remote Chiller Evaporator Option with Field Installation Kit Allows chilled water to be generated remotely from the condensing section.
Application Considerations Certain application constraints should be considered when sizing, selecting and installing Trane aircooled condensing units. Unit reliability is dependent upon these considerations. Where your application varies from the guidelines presented, it should be reviewed with the local Trane sales engineer. Unit Sizing Unit capacities are listed in the performance data section. Intentionally oversizing a unit to assure adequate capacity is not recommended.
Application Considerations Condenser coils and fan discharge must be kept free of snow and other obstructions to permit adequate air flow for satisfactory unit operation. Effect of Altitude on Capacity Condensing unit capacities given in the performance data tables are at sea level. At elevations substantially above sea level, the decreased air density will decrease condenser capacity and, therefore, unit capacity and efficiency. The adjustment factors in Table 4, p.
Application Considerations Water Temperature Limits RAUJ with remote EVP chiller performance data is based on a water temperature drop of 10°F. Full load chilled water temperature drops from 8 to 14°F may be used as long as minimum and maximum water temperature and minimum and maximum flow rates are not violated. Leaving water temperatures below 42°F require freeze protection down to 15°F. The maximum water temperature that can be circulated through the chiller when the unit is not operating is 125°F.
Selection Procedure Net capacity curves for the RAUJ condensing units are given in the performance data section. When matched with a coil curve, the resultant point of intersection will be the system design balance point. The design operating suction temperature and capacity can then be read directly from the graph. Note: It is usually necessary to account for suction and liquid line losses in the performance . The actual losses are determined by the interconnecting piping.

Mechanical Specifications 20 to 120-ton Condensing Units General All air-cooled condensing units have scroll compressors and are factory assembled and wired. Each unit is shipped from the factory with a nitrogen holding charge. 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.
Mechanical Specifications Remote Evaporator Chillers The remote chiller control option includes an interface panel in the main unit control box and a remote mounted control box that is customer installed. The remote mounted box contains the Honeywell W7100G controller. The chiller controller has an adjustable 0-10°F control band with integrating logic, built in fixed-off timers and field installed discharge water temperature sensors for control and chiller freeze protection.
