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.

Application Considerations Certain application constraints should be considered when sizing, selecting and installing Trane air-cooled condensing units. Unit reliability is dependent upon these considerations. Where your application varies from the guidelines presented, it should be reviewed with the localTrane sales engineer. Unit Sizing Unit capacities are listed in the performance data section on pages 11 to 24. Intentionally oversizing a unit to assure adequate capacity is not recommended.
Selection Procedure RAUC/AIR HANDLER Standard Selection Procedure Selection Procedure Net capacity curves for the RAUC condensing units are given on pages 14 through 23.These graphs can be used to cross plot an evaporator (EVP) performance 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.

Standard Options 20 through 60-Ton Condensing Units System Control Options Select one of the four following control options to meet your application requirements. • No System Control provides the compressors wired to a terminal strip inside the control panel. The temperature controller must be field provided and installed. The 20, 25 and 30-ton have two capacity steps. The 40, 50 and 60-ton sizes have four steps available.
Standard Options 80 through 120-Ton Condensing Units System Control Options Select one of the three following control options to meet your application requirements. • Supply Air VAV includes a multi-step, demand oriented, microprocessor-based Honeywell W7100 discharge air controller. W7100 control is designed for shut-off VAV systems. Average discharge air temperature is maintained by modulating an economizer and if needed, simultaneously sequencing stages of mechanical cooling.
