Features and Benefits
World Class Energy Efficiency
The importance of energy efficiency cannot be understated. Fortunately, ASHRAE has created a
guideline emphasizing its importance. Nonetheless, energy is often dismissed as an operational
cost over which the owner has little control.That perception results in missed opportunities for
energy efficiency, reduced utility bills, and higher profits. Lower utility bills directly affect
profitability. Every dollar saved in energy goes directly to the bottom line.Trane's RTAC is one way
to maximize your profits.

ASHRAE Standard 90.1 and Executive Order
AllTrane air-cooled chillers meet the new efficiency levels mandated by ASHRAE Standard 90.1.
This new standard requires higher efficiencies than past technologies can deliver.The US Federal
Government has adopted standard 90.1 and, in some cases, requires even higher efficiencies.
Federal Executive Order mandates energy consuming devices procured must be in the top 25% of
their class. In the case of chillers, that product standard is ASHRAE 90.1.Trane's RTAC meets and
exceeds the efficiency requirements of 90.1, while the high and extra efficiency RTAC can meet the
"stretch goals" of Executive Order.

Precise Capacity Control
Trane's patented unloading system allows the compressor to modulate infinitely and exactly match
building loads. At the same time chilled water temperatures will be maintained within +/- 1/2ºF
(0.28°C) of setpoint. Screw or scroll chillers with stepped capacity control do well to maintain chilled
water temperatures within 2ºF (1.1°C) of setpoint. Stepped control also results in over cooling
because rarely does the capacity of the machine match the building load.The result can be 10%
higher energy bills.Trane's RTAC optimizes the part load performance of your machine for energy
efficiency, precise control for process applications, and your personal comfort regardless of the
weather outside.

Excellent Reliability
A buildings environment is expected to be comfortable. When it is, no one says a word. If it's not…
that's a different story.The same is true with chillers. No one ever talks about chillers, yet alone
compressors, until they fail, and tenants are uncomfortable and productivity is lost.Trane's helical
rotary compressors have been designed and built to stay running when you need them.

Fewer moving parts
Trane's helical rotary compressors have only two major rotating parts: the male and female rotor.
A reciprocating compressor can have more than 15 times that number of critical parts. Multiples
of pistons, valves, crankshafts, and connecting rods in a reciprocating unit all represent different
failure paths for the compressor. In fact, reciprocating compressors can easily have a failure rate
four times of a helical rotor. Combine that with two to three reciprocating compressors for each
helical rotary compressor on chillers of equal tonnage, and statistics tell you it's a matter of time
before you lose a reciprocating compressor.

Robust components
Helical rotary compressors are precisely machined using state of the art processes from solid metal
bar stock.Tolerances are maintained within a micron or less than a tenth of the diameter of a
human hair.The resulting compressor is a robust yet highly sophisticated assembly capable of
ingesting liquid refrigerant without risk of damage.

Features and Benefits

Condenser coils
Trane's condenser coils are manufactured with the same philosophy as the compressors; they're
built to last. Even though manufacturing processes have allowed thinner and thinner materials in
their assembly, with obvious material and manufacturing savings,Trane's coil material did not
change with the RTAC generation of air cooled chillers. Substantial condenser fins, that do not
require additional coating in non-corrosive environments, contribute to the highest reliability
standards for air-cooled chillers in the industry.

Superior Control
The Adaptive Control™ microprocessor system enhances the air-cooled Series R chiller by
providing the very latest chiller control technology. With the Adaptive Control microprocessor,
unnecessary service calls and unhappy tenants are avoided.The unit is designed not to trip or
unnecessarily shut down. Only when theTracer™ chiller controllers have exhausted all possible
corrective actions and the unit is still violating an operating limit will the chiller shut down. Controls
on other equipment typically shut down the chiller, usually just when it is needed the most.
For example: A typical five year old chiller with dirty coils might trip out on high pressure cutout
on a 100°F (38°C) day in August. A hot day is just when comfort cooling is needed the most. In
contrast, the air-cooled Series R chiller with an Adaptive Control microprocessor will stage fans on,
modulate electronic expansion valves, and modulate slide valve positions as the chiller approaches
a high pressure cutout, thereby keeping the chiller online when you need it the most.

Simple Installation

RLC-PRC039B-EN

•

Factory Installed Flow Switch. Installed in the optimum location in the piping for reduced
chiller installation cost and superior flow sensing, reducing the potential for nuisance trips.

•

Close Spacing Installation.The air-cooled Series R™ Chiller has the tightest recommended
side clearance in the industry, four feet for maximum performance. In situations where
equipment must be installed with less clearance than recommended, which frequently occurs
in retrofit applications, restricted airflow is common. Conventional chillers may not work at all.
However, the air-cooled Series R chiller with Adaptive Control™ microprocessor will make as
much chilled water as possible given the actual installed conditions, stay on line during
unforeseen abnormal conditions, and optimize the unit performance. Consult yourTrane sales
engineer for more details.

•

Factory Testing Means Trouble Free Startup. All air-cooled Series R chillers are given a
complete functional test at the factory.This computer based test program completely checks
the sensors, wiring, electrical components, microprocessor function, communication
capability, expansion valve performance and fans. In addition, each compressor is run and
tested to verify capacity and efficiency. Where applicable, each unit is factory preset to the
customer's design conditions; an example would be leaving liquid temperature setpoint.The
result of this test program is that the chiller arrives at the job site fully tested and ready for
operation.

•

Factory Installed and Tested Controls/Options Speed Installation. All Series R chiller
options, including main power supply disconnect, low ambient control, ambient temperature
sensor, low ambient lockout, communication interface and ice making controls, are factory
installed and tested. Some manufacturers send accessories in pieces to be field installed. With
Trane, the customer saves on installation expense and has assurance that ALL chiller controls/
options have been tested and will function as intended.

Features and Benefits

Unit Performance Testing
The AHRI Certification Program has had a certification program covering air-cooled water chillers
for many years. With this in mind, customers may ask, "Do I need to factory performance test my
chiller?"
Trane began promoting factory performance tests for water-cooled water chillers in 1984 for the
same reasons it is valid today for air-cooled water chillers, to show we stand behind the products
we design and build.
The benefits of a performance test include verification of performance, prevention of operational
problems, and assurance of a smooth startup. Only a performance test conducted in a laboratory
or laboratory grade facility will confirm both performance and operation of a specific chiller.
While most factory performance tests go smoothly, should problems occur,Trane personnel can
quickly correct them and the chiller will ship as specified. Job site diagnosis, ordering of parts, and
waiting for delivery of replacement components is significantly reduced.
A factory performance test reduces startup time, thereby saving job site expense. A chiller that has
been tested is operation and performance proven.This allows the installing contractor to
concentrate on proper electrical wiring and water piping, and the service technicians to concentrate
on proper refrigerant charge, safeties diagnosis and initial logging of the chiller. Means of obtaining
full load on the chiller and proving its performance do not have to be determined by engineers or
contractors, thus saving time.The certified test report documents performance for the unit as built.
In addition, factory testing significantly reduces commissioning time and risk by reintroducing
manufacturer responsibility, where its mitigation should reside.
When a factory performance test is requested, the test can be conducted at the specified design
conditions for all packaged chillers.The test facility has the capability to control ambient test
conditions to assure our customers that our chillers will perform as predicted.
Rapid Restart™ testing is also available to demonstrate the chiller’s rapid restart capabilities for
disaster relief.While the chiller is operating at customer specified full load conditions, power to the
chiller is cut and the customer can witness how quickly the chiller will return to full load.
For more information on test performance testing, see brochure RL-SLB012-EN.

Application Considerations
Important
Certain application constraints should be considered when sizing, selecting and installingTrane aircooled Series R chillers. Unit and system reliability is often dependent upon proper and complete
compliance with these considerations.When the application varies from the guidelines presented,
it should be reviewed with your localTrane sales engineer.

Unit Sizing
Unit capacities are listed in the performance data section. Intentionally over sizing a unit to assure
adequate capacity is not recommended. Erratic system operation and excessive compressor
cycling are often a direct result of an oversized chiller. In addition, an oversized unit is usually more
expensive to purchase, install, and operate. If over sizing is desired, consider using multiple units.

Water Treatment
Dirt, scale, products of corrosion and other foreign material will adversely affect heat transfer
between the water and system components. Foreign matter in the chilled water system can also
increase pressure drop and consequently, reduce water flow. Proper water treatment must be
determined locally, depending on the type of system and local water characteristics. Neither salt
nor brackish water is recommended for use inTrane air-cooled Series R chillers. Use of either will
lead to a shortened life to an indeterminable degree.TheTrane Company encourages the
employment of a reputable water treatment specialist, familiar with local water conditions, to assist
in this determination and in the establishment of a proper water treatment program.

Effect Of Altitude On Capacity
Air-cooled Series R chiller capacities given in the performance data tables are for use at sea level.
At elevations substantially above sea level, the decreased air density will reduce condenser
capacity and, therefore, unit capacity and efficiency.

Ambient Limitations
Trane air-cooled Series R chillers are designed for year round operation over a range of ambient
temperatures.The Model RTAC chiller will operate as standard in ambient temperatures of 25°F to
115°F (-4°C to 46°C). With the low ambient option, these units will operate down to 0°F (-18°C). If
an ambient temperature as high as 125°F (51°C) is the basis for design, the high ambient option
will permit the chiller to run without going into a limiting condition. For installations in areas with
large ambient differences, the wide ambient option will allow the chiller to perform uninhibited
from 0°F to 125°F (-18°C to 51°C).

Water Flow Limits
The minimum and maximum water flow rates are given in the General Data tables. Evaporator flow
rates below the tabulated values will result in laminar flow causing freeze up problems, scaling,
stratification and poor control. Flow rates exceeding those listed may result in excessive tube
erosion.
Note: Flow rates in General Data tables are for water only.They do not include glycol.

Leaving Water Temperature Limits
Trane air-cooled Series R chillers have three distinct leaving water categories: standard, low
temperature, and ice making.The standard leaving solution temperature range is 40 to 65°F (4.4
to 15.6°C). Low temperature machines produce leaving liquid temperatures less than 40°F (4.4°C).
Since liquid supply temperature setpoints less than 40°F (4.4°C) result in suction temperatures at
or below the freezing point of water, a glycol solution is required for all low temperature machines.
Ice making machines have a leaving liquid temperature range of 20 to 60°F (-6.7 to 15.6°C). Ice
making controls include dual setpoint controls and safeties for ice making and standard cooling
capabilities. Consult your localTrane sales engineer for applications or selections involving low

Application Considerations

temperature or ice making machines.The maximum water temperature that can be circulated
through an evaporator when the unit is not operating is 108°F (42°C).

Flow Rates Out of Range
Many process cooling jobs require flow rates that cannot be met with the minimum and maximum
published values for the Model RTAC evaporator. A simple piping change can alleviate this
problem. For example: A plastic injection molding process requires 80 gpm (5.1 l/s) of 50°F (10°C)
water and returns that water at 60°F (15.6°C).The selected chiller can operate at these
temperatures, but has a minimum flow rate of 120 gpm (7.6 l/s).The system layout in Figure A1 can
satisfy the process.
Figure 1. Flow rate out of range system layout

Flow Control
Trane requires the chilled water flow control in conjunction with the Air-Cooled Series R Chiller to
be done by the chiller.This will allow the chiller to protect itself in potentially harmful conditions.

Supply Water Temperature Drop
The performance data for theTrane air-cooled Series R chiller is based on a chilled water
temperature drop of 10°F (5.6°C). Chilled water temperature drops from 6 to 18°F (3.3 to 10°C) may
be used as long as minimum and maximum water temperatures and flow rates are not violated.
Temperature drops outside this range are beyond the optimum range for control and may
adversely affect the microcomputer's ability to maintain an acceptable supply water temperature
range. Further, temperature drops of less than 6°F (3.3°C) may result in inadequate refrigerant
superheat. Sufficient superheat is always a primary concern in any refrigerant system and is
especially important in a package chiller where the evaporator is closely coupled to the
compressor.When temperature drops are less than 6°F (3.3°C), an evaporator runaround loop may
be required.

Leaving Water Temperature Out of Range
Many process cooling jobs require temperature ranges that cannot be met with the minimum and
maximum published values for the Model RTAC evaporator. A simple piping change can alleviate
this problem. For example: A laboratory load requires 120 gpm (7.6 l/s) of water entering the
process at 85°F (29.4°C) and returning at 95°F (35°C).The accuracy required is better than the
cooling tower can give.The selected chiller has adequate capacity, but a maximum leaving chilled
water temperature of 60°F (15.6°C).
In Figure A2, both the chiller and process flow rates are equal.This is not necessary. For example,
if the chiller had a higher flow rate, there would simply be more water bypassing and mixing with
warm water.

Application Considerations

Figure 2. Temperature out of range system layout

Variable Flow in the Evaporator
An attractive chilled water system option may be a variable primary flow (VPF) system. VPF
systems present building owners with several cost saving benefits that are directly related to the
pumps.The most obvious cost savings result from eliminating the secondary distribution pump,
which in turn avoids the expense incurred with the associated piping connections (material, labor),
electrical service, and variable frequency drive. Building owners often cite pump related energy
savings as the reason that prompted them to install a VPF system.
The evaporator on the Model RTAC can withstand up to 50 percent water flow reduction as long
as this flow is equal to or above the minimum flow rate requirements.The microprocessor and
capacity control algorithms are designed to handle a maximum of 10% change in water flow rate
per minute in order to maintain ± 0.5°F (0.28°C) leaving evaporator temperature control. For
applications in which system energy savings is most important and tight temperature control is
classified as +/- 2°F (1.1°C), up to 30 percent changes in flow per minute are possible.
With the help of a software analysis tool such as System Analyzer™, DOE-2 orTRACE™, you can
determine whether the anticipated energy savings justify the use of variable primary flow in a
particular application. It may also be easier to apply variable primary flow in an existing chilled
water plant. Unlike the "decoupled" system design, the bypass can be positioned at various points
in the chilled water loop and an additional pump is unnecessary.

Series Chiller Arrangements
Another energy saving strategy is to design the system around chillers arranged in series.The
actual savings possible with such strategies depends on the application dynamics and should be
researched by consulting yourTrane Systems Solutions Representative and applying an analysis
tool from theTrace software family. It is possible to operate a pair of chillers more efficiently in a
series chiller arrangement than in a parallel arrangement. It is also possible to achieve higher
entering to leaving chiller differentials, which may, in turn, provide the opportunity for lower chilled
water design temperature, lower design flow, and resulting installation and operational cost
savings.TheTrane screw compressor also has excellent capabilities for “lift,” which affords an
opportunity for “lift,” which affords an opportunity for savings on the evaporator water loop.
Series chiller arrangements can be controlled in several ways. Figure A3 shows a strategy where
each chiller is trying to achieve the system design set point. If the cooling load is less than 50 percent
of the systems capabilities, either chiller can fulfill the demand. As system loads increase, the
Chiller 2 becomes preferentially loaded as it attempts to meet the leaving chilled water setpoint.
Chiller 1 will finish cooling the leaving water from Chiller 2 down to the system design setpoint.

RLC-PRC039B-EN

Application Considerations

Staggering the chiller set points is another control technique that works well for preferentially
loading Chiller 1. If the cooling load is less than 50 percent of the system capacity, Chiller 1 would
be able to satisfy the entire call for cooling. As system loads increase, Chiller 2 is started to meet
any portion of the load that Chiller 1 can not meet.
Figure 3. Typical series chiller arrangement

Typical Water Piping
All building water piping must be flushed prior to making the final connections to the chiller.To
reduce heat loss and prevent condensation, insulation should be installed. Expansion tanks are
also usually required so that chilled water volume changes can be accommodated.

Short Water Loops
The proper location of the temperature control sensor is in the supply (outlet) water connection or
pipe.This location allows the building to act as a buffer and assures a slowly changing return water
temperature. If there is not a sufficient volume of water in the system to provide an adequate buffer,
temperature control can be lost, resulting in erratic system operation and excessive compressor
cycling. A short water loop has the same effect as attempting to control from the building return
water.Typically, a two minute water loop is sufficient to prevent problems.Therefore, as a
guideline, ensure the volume of water in the evaporator loop equals or exceeds two times the
evaporator flow rate in gallons per minute. For a rapidly changing load profile, the amount of
volume should be increased.To prevent the effect of a short water loop, the following items should
be given careful consideration: A storage tank or larger header pipe to increase the volume of water
in the system and, therefore, reduce the rate of change of the return water temperature.

Application Considerations

Typical Unit Installation
Outdoor HVAC equipment must be located to minimize noise and vibration transmission to the
occupied spaces of the building structure it serves. If the equipment must be located in close
proximity to a building, it could be placed next to an unoccupied space such as a storage room,
mechanical room, etc. It is not recommended to locate the equipment near occupied, sound
sensitive areas of the building or near windows. Locating the equipment away from structures will
also prevent sound reflection, which can increase levels at property lines, or other sensitive points.
When physically isolating the unit from structures, it is a good idea to not use rigid supports, and
to eliminate any metal-to-metal or hard material contact, when possible.This includes replacing
spring or metal weave isolation with elastomeric isolators. Figure A4 illustrates isolation
recommendations for the RTAC.
For chiller sound ratings, installation tips and considerations on chiller location, pipe isolation, etc.,
refer to theTrane Air-Cooled Series R Chillers Sound Data and Application Guide for Noise
Sensitive Installations.

System Options - Ice Storage
Trane air-cooled Series R Chillers are well suited for ice production. An air-cooled machine typically
switches to ice production at night.Two things happen under this assumption. First, the leaving
brine temperature from the evaporator is lowered to around 22 to 24°F (-5.5 to -4.4°C). Second, the
ambient temperature has typically dropped about 15 to 20°F (8.3 to 11°C) from the peak daytime
ambient.This effectively places a lift on the compressors that is similar to daytime running
conditions.The chiller can operate in lower ambient at night and successfully produce ice to
supplement the next day's cooling demands.
The Model RTAC produces ice by supplying ice storage tanks with a constant supply of glycol
solution. Air-cooled chillers selected for these lower leaving fluid temperatures are also selected
for efficient production of chilled fluid at nominal comfort cooling conditions.The ability ofTrane
chillers to serve “double duty” in ice production and comfort cooling greatly reduces the capital
cost of ice storage systems.
When cooling is required, ice chilled glycol is pumped from the ice storage tanks directly to the
cooling coils. No expensive heat exchanger is required.The glycol loop is a sealed system,
eliminating expensive annual chemical treatment costs.The air-cooled chiller is also available for
comfort cooling duty at nominal cooling conditions and efficiencies.The modular concept of glycol
ice storage systems and the proven simplicity ofTraneTracer controllers allow the successful blend
of reliability and energy saving performance in any ice storage application.
The ice storage system is operated in six different modes: each optimized for the utility cost of the
hour.
1. Provide comfort cooling with chiller
2. Provide comfort cooling with ice
3. Provide comfort cooling with ice and chiller
4. Freeze ice storage
5. Freeze ice storage when comfort cooling is required
6. Off
Tracer optimization software controls operation of the required equipment and accessories to
easily transition from one mode of operation to another. For example:
Even with ice storage systems there are numerous hours when ice is neither produced or
consumed, but saved. In this mode the chiller is the sole source of cooling. For example, to cool
the building after all ice is produced but before high electrical demand charges take effect,Tracer
sets the air-cooled chiller leaving fluid setpoint to its most efficient setting and starts the chiller,
chiller pump, and load pump.

RLC-PRC039B-EN

11

Application Considerations

When electrical demand is high, the ice pump is started and the chiller is either demand limited or
shut down completely.Tracer controls have the intelligence to optimally balance the contribution
of ice and chiller in meeting the cooling load.
The capacity of the chiller plant is extended by operating the chiller and ice in tandem.Tracer rations
the ice, augmenting chiller capacity while reducing cooling costs.When ice is produced,Tracer will
lower the air-cooled chiller leaving fluid setpoint and start the chiller, ice and chiller pumps, and
other accessories. Any incidental loads that persist while producing ice can be addressed by
starting the load pump and drawing spent cooling fluid from the ice storage tanks.

LCD Touch Screen Display
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.
Display Features Include:
• LCD touch screen with LED backlighting, for scrolling access to input and output operating
information
• Single screen, folder/tab style display of all available information on individual components
(evaporator, condenser, compressor, etc.)
• Password entry/lockout system to enable or disable display
• Automatic and immediate stop capabilities for standard or immediate manual shutdown
• Fast, easy access to available chiller data in tabbed format, including:
• Modes of operation, including normal cooling as well as ice making
• Water temperatures and setpoints
• Loading and limiting status and setpoints
• Outdoor air temperature
• Start/stop differential timers
• Pump status and override
• Chilled water reset settings
• Optional external setpoints, including:
• Chilled water, demand limit, ice building
Reports, listed on a single tabbed screen for easy access, including:
• ASHRAE, containing all guideline 3 report information
• Evaporator, condenser, compressor
Evaporator, condenser, and compressor reports containing all operational information on
individual components, including:
• Water temperatures, refrigerant pressures, temperatures, and approach
• Flow switch status, EXV position, compressor starts and run time
Alarm and diagnostic information, including:
• Flashing alarms with touch screen button for immediate address of alarm condition
• Scrollable list of last ten active diagnostics
• Specific information on applicable diagnostic from list of over one hundred
• Automatic or manual resetting diagnostic types

Adaptive Controls
Adaptive Controls directly sense the control variables that govern the operation of the chiller:
evaporator pressure and condenser pressure. When any one of these variables approaches a limit
condition when damage may occur to the unit or shutdown on a safety, Adaptive Controls takes
corrective action to avoid shutdown and keep the chiller operating.This happens through
combined actions of compressor and/or fan staging. Whenever possible, the chiller is allowed to
continue making chilled water.This keeps cooling capacity available until the problem can be
solved. Overall, the safety controls help keep the building or process running and out of trouble.

RLC-PRC039B-EN

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.
•

External Auto/Stop - A job site provided contact closure will turn the unit on and off.

•

Chilled Water Flow Interlock - A job site provided contact closure from a chilled water pump
contactor or a flow switch is required and will allow unit operation if a load exists.This feature
will allow the unit to run in conjunction with the pump system.

•

External Interlock - A job site supplied contact opening wired to this input will turn the unit off
and require a manual reset of the unit microcomputer.This closure is typically triggered by a
job site supplied system such as a fire alarm.

•

Chilled Water Pump Control - Unit controls provide an output to control the chilled water
pump(s). One contact closure to the chiller is all that is required to initiate the chilled water
system. Chilled water pump control by the chiller is a requirement on the Air-Cooled Series R.

•

Chilled WaterTemperature Reset -The reset can be based on return water temperature or
outdoor air temperature.

Hardwire Points
Microcomputer controls allow simple interface with other control systems, such as time clocks,
building automation systems, and ice storage systems via hardwire points.This means you have
the flexibility to meet job requirements while not having to learn a complicated control system.
Remote devices are wired from the control panel to provide auxiliary control to a building
automation system. Inputs and outputs can be communicated via a typical 4–20 mA electrical
signal, an equivalent 2–10 Vdc signal, or by utilizing contact closures. Contact closures may be
used to trigger job site supplied alarm lights or alarm bells.
This setup has the same features as a stand alone water chiller, with the possibility of having
additional optional features:
• Circuit enable/disable
• Ice making enable/status
• External chilled water setpoint, external demand limit setpoint
• Alarm indication contacts provides three single pole double throw contact closures to
indicate: compressor on/off status, compressor running at maximum capacity, failure has
occurred (ckt 1/ckt 2)

BACnet Interface
BACnet interface capabilities are available, with communication link via single twisted-pair wiring
to a factory-installed and tested communication board.

• Sequences starting of chillers to optimize the overall chiller plant energy efficiency
– Individual chillers operate as base, peak, or swing based on capacity and efficiency
– Automatically rotates individual chiller operation to equalize runtime and wear
between chillers.
– Evaluates and selects the lowest energy consumption alternative from an overall
system perspective.
Easy Operation and Maintenance
• Remote monitoring and control
• Displays both current operation conditions and scheduled automated control actions
• Concise reports assist in planning for preventative maintenance and verifying performance
• Alarm notification and diagnostic messages aid in quick and accurate troubleshooting

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.The LAN allows building operators
to manage these varied components as one system from any personal computer with web access.
The benefits of this system are:

RLC-PRC039B-EN

•

Improved usability with automatic data collection, enhanced data logging, easier to create
graphics, simpler navigation, pre-programmed scheduling, reporting, and alarm logs.

•

Flexible technology allows for system sizes from 30-120 unit controllers with any combination
of LonTalk or BACnet unit controllers.

•

LEED certification through site commissioning report, energy data collection measurement,
optimizing energy performance, and maintaining indoor air quality.

•

Energy savings programs include: fan pressure optimization, ventilation reset, and chiller plant
control (adds and subtracts chillers to meet cooling loads).

Notes:
1. Voltage Utilization Range: +/- 10% of rated voltage. Rated voltage (use range): 400 volt (360-440)
2. As standard, 140-200 ton units have a single point power connection. Optional dual point power connections are available. As standard, 250-400 ton units
have dual point power connections. Optional single point power connections are available on 400V/50 Hz units.
3. Control VA includes operational controls only. It does not include evaporator heaters. A separate 220/50/1, 15 amp customer provided power connection is
required to power the evaporator heaters (1640 watts).
4. RLA - Rated Load Amps
5. XLRA - Locked Rotor Amps - based on full winding (x-line) start units). YLRA for wye-delta starters is ~1/3 of LRA of x-line units.
6. MCA - Minimum Circuit Ampacity - 125 percent of largest compressor RLA plus 100 percent of all other loads.
7. Max fuse or MOPD = 225 percent of the largest compressor RLA plus 100 percent of the second compressor RLA, plus the sum of the condenser fan FLA.
(Use FLA per circuit, NOT FLA for the entire unit).
8. Local codes may take precedence.
9. All ambient means standard, low, high and wide ambient options.

Notes:
1. Voltage Utilization Range: +/- 10% of rated voltage. Rated voltage (use range): 400 volt (360-440)
2. As standard, 140-200 ton units have a single point power connection. Optional dual point power connections are available. As standard, 250-400 ton units
have dual point power connections. Optional single point power connections are available on 400V/50 Hz units.
3. Control VA includes operational controls only. It does not include evaporator heaters. A separate 220/50/1, 15 amp customer provided power connection
is required to power the evaporator heaters (1640 watts).
4. RLA - Rated Load Amps
5. XLRA - Locked Rotor Amps - based on full winding (x-line) start units). YLRA for wye-delta starters is ~1/3 of LRA of x-line units.
6. MCA - Minimum Circuit Ampacity - 125 percent of largest compressor RLA plus 100 percent of all other loads.
7. Max fuse or MOPD = 225 percent of the largest compressor RLA plus 100 percent of the second compressor RLA, plus the sum of the condenser fan FLA.
(Use FLA per circuit, NOT FLA for the entire unit).
8. Local codes may take precedence.
9. All ambient means standard, low, high and wide ambient options.

Mechanical Specifications
General
Units are leak and pressure tested at 390 psig high side, 250 psig low side, then evacuated and
charged. All Air-Cooled Series R Chillers are factory tested prior to shipment. Packaged units ship
with a full operating charge of oil and refrigerant. Unit panels, structural elements and control
boxes are constructed of galvanized steel and mounted on a welded structural steel base. Unit
panels and control boxes are finished with a baked on powder paint, and the structural base with
an air dry paint. All paint meets the requirement for outdoor equipment of the US Navy and other
federal government agencies.

Evaporator
The evaporator is a tube-in-shell heat exchanger design with internally and externally finned
copper tubes roller expanded into the tube sheet.The evaporator is designed, tested and stamped
in accordance with ASME for a refrigerant side working pressure of 200 psig.The evaporator is
designed for a water side working pressure of 150 psig. Water connections are grooved pipe. Each
shell includes a vent, a drain and fittings for temperature control sensors and is insulated with
3/4 inch equal insulation (K=0.28). Evaporator heaters with thermostat are provided to help protect
the evaporator from freezing at ambient temperatures down to -20°F (-29°C). Factory installed flow
switch is installed on a pipe stub in the evaporator inlet.

Condenser and Fans
Air-cooled condenser coils have aluminum fins mechanically bonded to internally finned seamless
copper tubing.The condenser coil has an integral subcooling circuit. Condensers are factory proof
and leak tested at 506 psig. Direct drive vertical discharge condenser fans are dynamically
balanced.Totally enclosed air over motors completely seal the motor windings to prevent
exposure to ambient conditions.Three-phase condenser fan motors with permanently lubricated
ball bearings and internal thermal overload protection are provided. Standard units will start and
operate between 25 to 115°F (-4 to 46°C) ambient.

Compressor and Lube Oil System
The rotary screw compressor is semi-hermetic, direct drive, 3000 rpm, 50 Hz, with capacity control
slide valve, a load/unload valve, rolling element bearings, differential refrigerant pressure oil pump

provide variable capacity modulation over the entire operating range.

Unit Controls
All unit controls are housed in an outdoor rated weather tight enclosure with removable plates to
allow for customer connection of power wiring and remote interlocks. All controls, including
sensors, are factory mounted and tested prior to shipment. Microcomputer controls provide all
control functions including startup and shut down, leaving chilled water temperature control,
evaporator flow proving, compressor and electronic expansion valve modulation, fan sequencing,
anti-recycle logic, automatic lead/lag compressor starting and load limiting.The unit control
module, utilizing Adaptive Control™ microprocessor, automatically takes action to avoid unit
shutdown due to abnormal operating conditions associated with low refrigerant pressure, high
condensing pressure and motor current overload. Should the abnormal operating condition
continue until a protective limit is violated, the unit will be shut down. Unit protective functions
