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. The Trane 3-D Scroll provides important reliability and efficiency benefits. The 3-D Scroll allows the orbiting scrolls to touch in all three dimensions, forming a completely enclosed compression chamber which leads to increased efficiency. In addition, the orbiting scrolls only touch with enough force to create a seal; there is no wear between the scroll plates. The fixed and orbiting scrolls are made of high strength cast iron which results in less thermal distortion, less leakage, and higher efficiencies. The most outstanding feature of the 3-D Scroll compressor is the greater tolerance to slugging tha reciprocating compressors. Low Torque Variation The 3-D Scroll compressor has a very smooth compression cycle; torque variations are only 30 percent of that produced by a reciprocating compressor. This means that the scroll compressor imposes very little stress on the motor resulting in greater reliability. Low torque variation reduces noise and vibration Suction Gas Cooled Motor Compressor motor efficiency and reliability is further optimized with the latest scroll design. Cool suction gas keeps the motor cooler for longer life and better efficiency. Proven Design Through Testing and Research With over twenty years of development and testing, Trane 3-D Scroll compressors have undergone more than 400,000 hours of laboratory testing and field operation. This work combined with over 25 patents makes Trane the worldwide leader in air conditioning scroll compressor technology. Voltage Power Supply 20 to 120-ton units have four voltage options in 200, 230, 460 and 575. Passive Manifolding Trane offers a parallel manifolding scheme that uses no moving mechanical parts. This feature assures continuous oil return, again providing greater system reliability. And greater reliability means optimal performance over the life of the unit. Additional Features System Control Options In addition to “no system control” option, Trane offers three system control options on 20-60 ton units and two system control options on the 80-120 ton units, each using solid- state electronics. These options allow the unit to be ordered with the controls needed, saving field installation costs. 4 SS-PRC030-EN 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. The EVP option is controls only and includes unit controller, discharge water temperature sensor and water freezestat. Accessory kit includes evaporator, with mounting hardware and insulation, water strainer, minimum water flow limit switch and evaporator pipe stubs with couplings. Control option must be selected with accessory kit. 20 to 120-Ton Units Standard Features • • • • • • • • Trane 3-D™ Scroll compressors Phase Loss/Reversal/Low Voltage Monitor Factory-installed Discharge and Liquid Line Service Valves Passive manifolding for 3-D Scroll compressors Standard ambient operating range 40°F to 125°F (115°F max ambient for EVP chiller) Heavy gauge galvanized steel frame Louvered panels for coil protection Slate gray air-dry paint finish Optional Features • • • • • • • • • • • • • • Remote chiller evaporator with field installation kit Non-fused disconnect (20 to 60-Ton Models) Low ambient option Hot gas bypass to the evaporator inlet Suction service valve Pressure gauges Return air sensor Unit spring isolators Neoprene-in-shear isolators cULus approval (not available for 50 Hz) Packed Stock Plus program (20 to 60-Ton Models) Extended Compressor Warranty Corrosion protected condenser coil Constant volume, VAV, and no controls options on 20 to 60-Ton models, VAV and no controls options on 80 to 120-Ton Models Packed Stock Plus Trane 20 to 60-ton air-cooled condensing units are available through the most flexible packed stock program in the industry.

SS-PRC030-EN 5 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. Erratic system operation and excessive compressor cycling are often a direct result of an oversized condensing unit. In addition, an oversized unit is usually more expensive to purchase, install and operate. If oversizing is desired, consider using two units. Unit Placement A base or foundation is not required if the selected unit location is level and strong enough to support the unit’s operating weight. Isolation and Sound Emission The most effective form of isolation is to locate the unit away from any sound sensitive area. Structurally transmitted sound can be reduced by using spring or rubber isolators. The isolators are effective in reducing the low frequency sound generated by compressors and, therefore, are recommended for sound sensitive installations. An acoustical engineer should always be consulted on critical applications. For maximum isolation effect, the refrigeration lines and electrical conduit should also be isolated. Use flexible electrical conduit. State and local codes on sound emissions should always be considered. Since the environment in which a sound source is located affects sound pressure, unit placement must be carefully evaluated. Servicing Adequate clearance for compressor servicing should be provided. Recommended minimum space envelopes for servicing are located in the dimensional data section of this catalog and can serve as guidelines for providing adequate clearance. The minimum space envelopes also allow for control panel door swing and routine maintenance requirements. Local code requirements may take precedence. Unit Location Unobstructed flow of condenser air is essential for maintaining condensing unit capacity and operating efficiency. When determining unit placement, careful consideration must be given to assure proper air flow across the condenser heat transfer surface. Failure to heed these considerations will result in warm air recirculation and coil air flow starvation. Warm air recirculation occurs when discharge air from the condenser fans is recycled back at the condenser coil inlet. Coil starvation occurs when free air flow to the condenser is restricted. Both warm air recirculation and coil starvation cause reductions in unit efficiency and capacity. In addition, in more severe cases, nuisance unit shutdowns will result from excessive head pressures. Accurate estimates of the degree of efficiency and capacity reduction are not possible due to the unpredictable effect of varying winds. When hot gas bypass is used, reduced head pressure increases the minimum ambient condition for proper operation. In addition, wind tends to further reduce head pressure. Therefore, it is advisable to protect the air-cooled condensing unit from continuous direct winds exceeding 10 miles per hour. Debris, trash, supplies, etc., should not be allowed to accumulate in the vicinity of the air-cooled condensing unit. Supply air movement may draw debris between coil fins and cause coil starvation. Special consideration should be given to units operating in low ambient temperatures. 6 SS-PRC030-EN 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. 12 can be applied directly to the catalog performance data to determine the unit’s adjusted performance. Ambient Considerations Start-up and operation at lower ambients requires sufficient head pressure be maintained for proper expansion valve operation. At higher ambients, excessive head pressure may result. Standard operating conditions are 40°F to 125°F (115°F max ambient for EVP chiller). With a low ambient damper, operation down to 0°F is possible. Minimum ambient temperatures are based on still conditions (winds not exceeding five mph). Greater wind velocities will result in increased minimum operating ambients. Units with hot gas bypass have a minimum operating ambient temperature of 10°F. For proper operation outside these recommendations, contact the local Trane sales office. Coil Frost Protection Frostat™ is standard on condensing units when the VAV option is ordered. Frostat™ consists of a ship-with thermostat for field installation on the suction line. A timer is also factory-installed to avoid short cycling. Frostat™ cycles the compressor off when the suction line is below 30°F. Refer to S/S-EB-43 for more detail. When hot gas valves must be used on 20 to 120-ton units, they can be ordered as a miscellaneous option. The 20 to 30-ton units require one valve; 40 to 60-ton units also require one valve except when no system control option is selected; this option requires two valves. The 80 to 120-ton units require one valve when Supply Air VAV control is selected. Two valves are required on all other 80 to 120-ton control options. Refrigerant Piping Special consideration must always be given to oil return. Minimum suction gas velocities must always be maintained for proper oil return. Utilize Tube Size and Component Selectionapplication guide SS-APG012-EN for proper system design. For special applications, call Clarksville Product Support. Note: Under certain conditions, R-410A refrigerant can present special challenges with piping and system design. Whenever refrigerant line set lengths approach 150 equivalent feet and/or design ambient temperature exceeds 115°F, contact your Trane Account Executive to review application requirements. Remote Chiller Evaporator Water Treatment Using untreated or improperly treated water may result in scaling, erosion, corrosion, and algae or slime buildup in the heat exchanger that will adversely affect system capacity. Proper water treatment must be determined locally and depends on the type of system and local water characteristics. Neither salt nor brackish water is recommended, either will lead to a shortened heat exchanger life. Trane encourages employment of a qualified water treatment specialist, familiar with local water conditions, to assist in the establishment of a proper water treatment program. Water Flow Limits The minimum and maximum water flow rates are given in Table 2, p. 12. Water flow rates below the tabulated values will result in laminar flow causing freeze-up problems, scaling, stratification and poor system control. Flow rates exceeding the maximum listed may result in very high pressure drop, erosion of the heat exchanger and damage to the water flow switch. SS-PRC030-EN 7 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. Evaporator damage may result above this temperature. Short Water Loops Adequate chilled water system water volume is an important system design parameter because it provides for stable chilled water temperature control and helps limit unacceptable short cycling of chiller compressors. Typically, a five-minute water loop circulation time is sufficient to prevent short water loop issues. Therefore, as a guideline, ensure the volume of water in the chilled water loop equals or exceeds five times the evaporator flow rate. For systems with a rapidly changing load profile the amount of volume should be increased. Note: Water volumes should be calculated as close as possible to maintain constant water flow through the water loop. Water Piping Foreign matter in the chilled water system will increase pressure drop and reduce water flow. Installation of a properly selected strainer is also necessary to prevent debris larger than 0.039” from entering the heat exchanger. All building water piping must be thoroughly flushed before making the final piping connections to the heat exchanger. To reduce heat loss and prevent condensation, insulation should be applied to piping. Expansion tanks are also generally required to accommodate chilled water volume changes. 8 SS-PRC030-EN 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. To plot the DX evaporator performance curve it is only necessary to obtain gross evaporator capacities for the given entering air conditions and cfm at two different saturated suction temperatures. The Trane Refrigeration Coil Computer Selection Program can be used to conveniently provide the necessary evaporator capacity values at the selected suction temperatures. Selection Example The RAUJ 20 to 120-Ton TOPSS™ selection program provides the ability to generate performance output for pre-selected Trane Modular Climate Changer evaporator coils with the RAUJ condensing units. To select a condensing unit and evaporator coil not available in the RAUJ TOPSS™ program, the example below can be used to cross-plot an evaporator coil with known performance with the RAUJ condensing unit From the Trane Refrigeration Coil Computer Selection Program: DX Evap Coil = Model Number DFDB42 - 42" X 60" / 4 Row / 144 FPF - FD/Delta-flo E Entering Coil Conditions = 80/67 DB/WB and 95°F Ambient - 8500 CFM Coil Performance @ 38F SST - 406.49 MBh Total Coil Performance @ 45F SST - 293.09 MBh Total Balance Point at 95°F Ambient = 370 MBh @ 40.2 SST Coils are identical fin series and circuiting on both simulations. Figure 1. 30 Ton condensing unit performance - RAUJ-C30 (60 Hz) 475 Evaporator coil line 406.49MBH @ 38F SST Net Capacity(MBH) 425 375 325 293.09MBH @ 45F SST 275 225 30 32 34 36 38 40 42 44 46 48 50 Saturated Suction(F) By plotting the two coil performance outputs across the RAUJC30 Net Capacity curve at their respective total MBH at the defined saturated suction temperatures and ignoring line losses,, we can see that the condenser/evaporator coil combination, at 95 F ambient, provides 370 MBH Net Capacity at 40.2 SST.

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. The 80, 100, and 120-ton sizes have six steps available. • Constant Volume Control (20 to 60-Ton Models) includes a W973 controller with two cool, four heat steps on the 20, 25 and 30-ton sizes. Four cool, four heat steps are provided on the 40, 50 and 60-ton sizes. The heating contacts are wired to terminals in the condensing unit control panel for easy interface with a field supplied electric duct heater or gas duct furnace. An optional return air sensor is available with this controller which provides the zone temperature input to the thermostat, thus generating the loading demand signal to the Honeywell W973 constant volume controller. • EVP Chiller Control consists of 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 water chiller controller has an adjustable 0-10°F control band using integrating logic, built-in fixed-off timers and field installed discharge water temperature sensors for control and chiller freeze protection. Pumpdown is provided. Lead-lag and multiple chiller control are not provided. There are two capacity steps on 20, 25 and 30-ton sizes, four capacity steps on 40, 50 and 60 ton sizes and six capacity steps on 80, 100 and 120ton sizes. • Supply Air VAV Control provides a Honeywell W7100A control system. This option is for use with shut-off VAV or other applications requiring control of supply air temperature. The control provides a voltage output for interface with field supplied components to provide simultaneous economizer operation. The discharge air sensor ships with the unit for field mounting. The standard VAV unit is provided with reliable coil frost protection in the form of Trane’s proven and patented Frostat™. Frostat™ is used in place of hot gas bypass. Low Ambient Control Option • Standard — Unit start-up and operation down to approximately 40°F at minimum compressor load. • Low Ambient — Factory-installed head pressure control damper assembly permits operation down to 0°F by maintaining proper head pressure. Ten minute timer is standard for protection against nuisance trips. Miscellaneous Options Select the miscellaneous options to meet your project requirements. • Non-Fused Unit Disconnect Switch (20 to 60-Ton Models) is mounted in the control box and provides for interruption of power for servicing the unit. Lugs are suitable for copper wires only. No overcurrent or short circuit protection is provided for the unit by this switch. • Hot Gas Bypass Valves are stocked and shipped with the unit for field installation. When suction pressure falls below the valve adjustable set point, the valve modulates hot gas to the inlet of the evaporator.

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. This air-dry paint finish is durable enough to withstand a minimum of 500-consecutive-hour salt spray application in accordance with standard ASTM B117. Compressor Trane 3-D Scroll compressors have a simple mechanical design with only three major moving parts. Scroll type compression provides inherently low vibration. The 3-D Scroll provides a completely enclosed compression chamber which leads to increased efficiency. Exhaustive testing on 3-D Scroll, including start up with the shell full of liquid, has proven that slugging does not fail involutes. Direct-drive, 3600 rpm, suction gas-cooled hermetic motor. Trane 3-D Scroll compressor includes centrifugal oil pump, oil level sightglass and oil charging valve. Split systems can have significantly more refrigerant than packaged systems and thus require controls to reliably manage this excess refrigerant. Each compressor shall have crankcase heaters installed, properly sized to minimize the amount of liquid refrigerant present in the oil sump during off cycles. Additionally, the condensing unit shall have controls to initiate a refrigerant pump down cycle at system shut down on each refrigerant circuit. To be operational, the refrigerant pump down cycle requires a field provided and installed isolation solenoid valve on the liquid line near the evaporator. Condenser Condenser coils are single or dual circuit having an all aluminum Microchannel design. The coils are burst tested and leak tested. Factory installed liquid line service valves are standard. Direct drive vertical discharge fans are statically and dynamically balanced. Three-phase motors have permanently lubricated ball bearings and thermal overload protection. Optional low ambient allows operating down to 0°F with external damper assembly for head pressure control. Refrigerant Circuits and Capacity Modulation 20 to 30-ton sizes are single circuit and have two steps of capacity. The 40 to 60-ton sizes are two circuits with four capacity steps. Each circuit has two compressors piped in parallel. Discharge and liquid line service valves are standard on each circuit. 80, 100, and 120-ton sizes are two circuits with six capacity steps. Each circuit has three compressors piped in parallel. Unit Control Factory-provided 115-volt control circuit includes fusing and control power transformer. The unit is wired with magnetic contactors for compressor and condenser motors, three-leg, solid-state compressor overload protection, and high-low pressure cutouts. Charge isolation, reset relay and anti-recycle compressor timer are provided. Corrosion Protected Condenser Coil All Aluminum Microchannel condenser coil protection shall consist of a corrosion resistant coating that shall withstand ASTM B117 Salt Spray test for 1000 hours and ASTM G85 A2 Cyclic Acidified Salt Fog test for 2400 hours. This coating shall be added after coil construction, covering all tubes, headers and fin edges, therefore providing optimal protection in more corrosive environments. 50 SS-PRC030-EN 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. There are two capacity steps on 20, 25 and 30-ton sizes, four capacity steps on 40, 50 and 60 ton sizes and six capacity steps on 80, 100 and 120 ton sizes. The remote chiller accessory kit includes the evaporator with mounting hardware and insulation, water strainer, minimum water flow limit switch and water side pipe stubs with couplings. The chiller is a stainless steel brazed plate heat exchanger designed for up to 150 psig water side working pressure and 430 psig refrigerant working pressure. Chiller mounting is intended for nonfreezing locations only. The strainer will prevent system debris larger than 0.039” from entering the evaporator.
