standard for that product. In the case of

chillers, that product standard is

ASHRAE 90.1. Trane’s RTAA 70-125

meets and exceeds the efficiency

requirements of 90.1, with some units

meeting the “stretch goals” of Executive

Order.

The RTAA 70-125 offers the same high

reliability of its larger predecessor

coupled with lowered sound levels,

increased energy efficiency, and reduced

physical footprint, all due to its advanced

design, low speed/direct drive

compressor and proven Series R^™

performance.

Some of the major advantages of the

Model RTAA 70-125 vs its larger

predecessor are:

• Higher energy efficiency

• Lower sound levels

• Smaller physical footprint

The Series R^™Model RTAA 70-125 is an

industrial grade design built for both the

industrial and commercial markets. It is

ideal for schools, hospitals, retailers,

office buildings, Internet service

providers and industrials.

ASHRAE Standard 90.1 and RTAA 70-

125 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 RTAA 70-125 is one

way to maximize your profits.

Risk. The US Federal Government has

adopted ASHRAE 90.1, and it’s expected

to be adopted domestically, if not

globally, in the future. Domestic

acceptance has already begun. Make

sure that your chillers as well as your

entire HVAC system complies, or you

may be caught retrofitting your project

with new equipment and paying extra

design dollars if the code is adopted

during construction.

setpoint, potentially eliminating the need

for external considerations to maintain

temperatures. Reciprocating and screw

chillers with stepped capacity control do

well to maintain chilled water

temperatures within 2ºF of setpoint.

Stepped control also results in

overcooling or undercooling your space

because rarely does the capacity of the

machine match the building load. The

result can be 10% higher energy bills.

Trane’s RTAA optimizes the part load

performance of your machine for energy

efficiency, precise temperature control

for all modes of operation, and your

personal comfort regardless of changing

conditions.

ASHRAE Standard 90.1 & Executive

Order - New technology applied to the

design, controls, and manufacturing

have created superior efficiency levels in

the RTAA 70-125 that are unmatched in

the industry. All Trane 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,

Excellent Reliability

A building 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 tenets

are uncomfortable and productivity is

lost. Trane’s helical rotary compressors

have a first year reliability rate of over

99%, which means our chillers stay

running when you need them.

Screw compressors were designed to

replace the inherent design flaws of a

reciprocating compressor. Trane’s helical

rotary compressor has successfully

achieved this goal, proven by the over

99% reliability rating of our compressor

in the first year of operation. A good

design like Trane’s should maintain this

level of reliability for several years of

chiller operation. Not all screw

will publish a reliability number. The

point is to make sure that you are getting

a reliable screw chiller design so that you

don’t end up with the downtime and lost

earnings that the industry is trying to

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 that of a helical rotor.

Combine this with two to three

Robust parts. 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. Contrast this to a

reciprocating compressor, which can be

destroyed by a single slug of liquid.

When coupled with Trane’s Adaptive

part-load performance of the Series R^™

chiller by minimizing superheat in the

evaporator and allowing the chiller to

run at reduced condensing

Modulating capacity control offers better

compressor reliability. Compressor

compressors, will decrease compressor

component life. Parts like motors and

valves do not stand up well to excessive

compressor cycling.

Chillers that have step capacity control

typically can only maintain water

temperature to around 2°F. With the

air-cooled Series R^™chiller, maintaining

accurate.

temperatures. Chillers which use

conventional TXV’s must run at higher

head pressures and consume more

power than necessary at part-loads.

Additionally, the electronic expansion

valve and its controls allow much better

stability and control over dynamic load

and head changes. Under these

conditions a conventional TXV may

never achieve control stability and

extended periods of TXV “hunting” and

liquid slugging are common.

Capacity Control and Load Matching

Infinitely variable compressor

modulation allows the compressor

capacity to exactly match the building

cooling load. Reciprocating and screw

chillers that rely on stepped capacity

control must run at a capacity equal to or

greater than the load. Much of this

excess capacity is lost because

overcooling goes toward building latent

heat removal, causing the building to be

dried beyond normal comfort

requirements. The result is an increase in

chiller energy costs, particularly at the

part-load conditions at which the chiller

operates most of the time.

sound applications.

Coil starvation occurs when free airflow

to (or from) the condenser is restricted.

Certain application constraints should be

considered when sizing, selecting and

installing Trane air-cooled Series R^™

chillers. Unit and system reliability is

often dependent upon properly and

completely complying with these

considerations. Where the application

varies from the guidelines presented, it

should be reviewed with your local

Trane sales engineer.

For maximum isolation effect, water

lines and electrical conduit should also

be isolated. Wall sleeves and rubber

isolated piping hangers can be used to

reduce the sound transmitted through

water piping. To reduce the sound

transmitted through electrical conduit,

use flexible electrical conduit.

Both warm air recirculation and coil

starvation cause reductions in unit

efficiency and capacity because of the

higher head pressures associated with

them. The air-cooled Series R^™chiller

offers an advantage over competitive

equipment in these situations.

Performance is minimally affected in

many restricted air flow situations due to

its unique condensing coil geometry.

Also, through its advanced Adaptive

Control^™microprocessor logic, the

chiller will attempt to stay on-line where

competitive chillers would usually shut

down.

State and local codes on sound

Unit Sizing

emissions should always be considered.

Since the environment in which a sound

source is located affects sound pressure,

unit placement must be carefully

evaluated. Sound power levels for Trane

air-cooled Series R^™chillers are available

on request.

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 chiller. In addition,

an oversized unit is usually more

expensive to purchase, install, and

operate. If oversizing is desired, consider

using two units.

Trane’s unique Adaptive Control

microprocessor has the ability to

3. Servicing

understand the operating environment

of the chiller and adapt to it by first

optimizing its performance and second,

staying on line through abnormal

conditions. For example, high ambient

temperatures combined with a restricted

air flow situation will generally not cause

the air-cooled Series R^™chiller to shut

down. Competitive chillers would

typically shut down on a high pressure

nuisance cut-out in these conditions.

Adequate clearance for evaporator and

compressor servicing should be

provided. Recommended minimum

space envelopes for servicing are

located in the dimensional data section

and can serve as a guideline for

providing adequate clearance. The

minimum space envelopes also allow

for control panel swing and routine

maintenance requirements. Local code

requirements may take precedence.

Unit Placement

1. Setting The Unit

A base or foundation is not required if

the selected unit location is level and the

base is strong enough to support the

unit’s operating weight as listed in Tables

W-1 and W-2.

Debris, trash, supplies, etc. should not be

allowed to accumulate in the vicinity of

the air-cooled Series R^™chiller. Supply

air movement may draw debris into the

condenser coil, blocking spaces between

coil fins and causing coil starvation.

2. 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

4. Unit Location

a. General

Unobstructed flow of condenser air is

essential to maintain chiller capacity and

operating efficiency. When determining

unit placement, careful consideration

must be given to assuring a sufficient

flow of air across the condenser heat

transfer surface. Two detrimental

conditions are possible and must be

avoided if optimum performance is to be

achieved: warm air recirculation and coil

starvation.

ELASTOMERIC vibration eliminators.

Spring isolators have proven to be of

little benefit on air-cooled Series R^™

chiller installations and are not

Application

Considerations

b. Provide Vertical Clearance

Vertical condenser air discharge must be

unobstructed. While it is difficult to

predict the degree of warm air

circulation, a unit installed as shown on

the left would have its capacity and

efficiency significantly reduced.

Performance data is based on free air

discharge.

c. Provide Lateral Clearance

The condenser coil inlet must not be

obstructed. A unit installed closer than

the minimum recommended distance to

a wall or other vertical riser may

experience a combination coil starvation

and warm air recirculation, resulting in

unit capacity and efficiency reductions.

Once again, the Adaptive Control^™

microprocessor will allow the chiller to

stay on line, producing the maximum

available capacity, even at less than

recommended lateral clearances.

The recommended lateral clearances are

depicted in the dimensional data section.

These are estimates and should be

reviewed with the local Trane sales

engineer at the jobsite.

d. Provide Sufficient Unit-to-Unit

Clearance

Units should be separated from each

other by a sufficient distance to prevent

warm air recirculation or coil starvation.

The air-cooled Series R^™chiller has the

lowest recommended unit-to-unit

clearance in the industry, eight feet.

Consult the local Trane sales engineer for

applications concerning close spacing

and restricted airflows.

e. Walled Enclosure Installations

When the unit is placed in an enclosure

or small depression, the top of the fans

should be no lower than the top of the

enclosure or depression. If they are,

consideration should be given to ducting

the top of the unit. Ducting individual

fans, however, is not recommended.

Such applications should always be

reviewed with the local Trane sales

engineer.

Application

Considerations

Water Treatment

The minimum ambient temperatures are

based on still conditions (winds not

exceeding five mph). Greater wind

velocities will result in a drop in head

pressure, therefore increasing the

minimum starting and operating

ambient temperature. Once again, the

Adaptive Control^™microprocessor will

attempt to keep the chiller on-line when

high or low ambient conditions exist,

making every effort to avoid nuisance

trip-outs and provide the maximum

allowable tonnage.

The standard leaving water temperature

range is 40 to 65°F. Low temperature

machines produce leaving water

temperatures between 0°F and 39°F.

Since water supply temperature

setpoints from 0 to 39°F 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 water temperature range of 20 to

65°F. Ice making controls include dual

setpoint controls and safeties for ice

making and standard cooling

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 waterflow. 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 in Trane air-

cooled Series R^™chillers. Use of either

will lead to a shortened life to an

indeterminable degree. The Trane

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.

Waterflow Limits

capabilities. Consult your local Trane

sales engineer for applications or

selections involving low temperature or

ice making machines.

The minimum waterflow rates are given

in Table G-1. Evaporator flow rates

below the tabulated values will result in

laminar flow causing freeze-up

problems, scaling, stratification and poor

control.

The maximum water temperature that

can be circulated through an evaporator

when the unit is not operating is 108°F.

The evaporator becomes thermal stress

limited at this temperature.

The maximum evaporator waterflow

rate is also given in the general data

section. Flow rates exceeding those

listed may result in excessive tube and

baffle erosion.

The capacities given in the performance

data section of this catalog are based on

water with a fouling factor of .00010. For

capacities at other fouling factors, see

adjustment factors in Table F-1.

2. Supply Water Temperature Drop

The performance data for the Trane air-

cooled Series R^™chiller is based on a

chilled water temperature drop of 10°F.

Temperature drops outside this range

will result in unit performance that

differs from that cataloged. For

performance data outside the 10°F

range, see Table F-1 for adjustment

factors. Chilled water temperature drops

from 6 to 18°F may be used as long as

minimum and maximum water

The evaporator can withstand up to 50

percent water flow reduction as long as

this flow is equal or above the minimum

gpm requirements.

Effect Of Altitude On Capacity

Air-cooled Series R^™chiller capacities

given in the performance data tables, P-1

through P-12, are for use 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 F-1 can be applied

directly to the catalog performance data

to determine the unit’s adjusted

Variable Evaporator Flow

Air-cooled Series R^™chillers have the

capability to handle variable evaporator

flow without losing leaving water

temperature control. Flow rates can be

varied up to 10% of design without

decreasing the leaving water

temperature and minimum and

maximum flow rates are not violated.

Temperature drops outside 6 to 18°F are

beyond the optimum range for control

and may adversely affect the

microcomputer’s ability to maintain an

performance.

1. Leaving Water Temperature Range

Trane air-cooled Series R^™chillers have

three distinct leaving water categories:

standard, low temperature, and ice

making.

Ambient Limitations

Trane air-cooled Series R^™chillers are

designed for year-round applications

over a range of ambients. Chillers from

70-125 tons offer operation for ambients

from 25 to 115°F as standard, and will

operate down to -10°F with the low

ambient option.

Further, temperature drops of less than

6°F may result in inadequate refrigerant

superheat. Sufficient superheat is always

a primary concern in any direct

expansion 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, an evaporator

runaround loop may be required.

Considerations

Typical Water Piping

unloading. However, it is still a good idea

to make sure the evaporator water loop

is sized sufficiently to help maintain

temperature control.

1. Series Operation

All building water piping must be

flushed prior to making 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.

A typical piping arrangement is shown in

Figure A-1.

Some systems require large chilled

water temperature drops (16 to 24°F).

For those installations, two units with

their evaporators in series are usually

required. Control of the units should be

from a common temperature controller

to prevent the separate thermostats

fighting one another and continually

hunting. It is possible to control from the

two individual unit controls, but a

common temperature controller

provides a positive method for

As a guideline, ensure the volume of

water in the evaporator loop equals or

exceeds two times the evaporator flow

rate. For a rapidly changing load profile,

the amount of volume should be

increased.

Short Water Loops

To prevent the effect of a short water

loop, the following items should be

given careful consideration:

The proper location of the temperature

control sensor is in the supply (outlet)

water. 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.

preventing control overlap, more closely

matches system load, and simplifies

compressor lead-lag capability.

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.

2. Parallel Operation

Some systems require more capacity or

standby capability than a single machine

can provide. For those installations, two

units with their evaporators in a parallel

configuration are typical. The only

effective way of controlling two units in

parallel is with a single temperature

controller. Two individual temperature

controllers are not capable of providing

reliable system control and will often

result in unsatisfactory operation.

Multiple Unit Operation

Whenever two or more units are used

on one chilled water loop, Trane

recommends that their operation be

controlled from a single control device,

such as a Trane Tracer^™system.

The Air-Cooled Series R^™70-125 ton

chiller has excellent leaving chilled water

control capabilities because of

exceptional controls, EXV and linear

Standard Features

Since the microcomputer provides all

control functions, it can easily indicate

such parameters as leaving chilled water

temperature and capacity stage.

If a failure does occur, one of over 90

individual diagnostic and operating

codes will be used to indicate the

problem, giving more specific

compressor or evaporator failures,

thereby minimizing nuisance shutdown.

The Unit Control Module (UCM) directly

senses the control variables that govern

the loading of the chiller: motor current

draw, evaporator temperature,

condenser temperature, etc. When any

one of the variables approaches a limit

condition where the unit may be

damaged or shutdown on a safety, the

UCM takes corrective action to avoid

shutdown and keep the chiller operating.

It does this through combined actions of

compressor slide valve modulation,

electronic expansion valve modulation

and fan staging. The UCM optimizes

total chiller power consumption during

normal operating conditions. During

abnormal operating conditions, the UCM

will continue to optimize chiller

controlled to fit into the overall building

automation strategy by using time of

day scheduling, timed override, duty

cycling, demand limiting, and chiller

sequencing. A building owner can

completely monitor the air-cooled Series

R^™chiller from the Tracer system, as all

of the monitoring information indicated

on the microcomputer can be read off

the Tracer system display. In addition, all

the powerful diagnostic information can

be read back at the Tracer system. Best

of all, this powerful capability comes

over a single twisted pair of wires!

Air-cooled Series R^™chillers can

interface with many different external

control systems, from simple stand-

alone units to ice making systems. Each

unit requires a single-source, three-

phase power supply and two 115-volt

power supplies. When an optional

control power transformer is used, a

single 115-volt supply handles the

evaporator heat tape. For basic stand-

alone applications, the interface with

outside control is no different than for

other Trane chillers. However, the RTAA

units have many features that can be

used to interface with building control

systems.

4. Chilled Water Pump Control

Unit controls provide an output to

control chilled water pump(s). One

contact closure to the chiller is all that is

required to initiate the chilled water

system.

5. Remote Running and Alarm Indication

Contacts

The unit provides three single-pole/

double-throw contact closures to

indicate that a failure has occurred, if any

compressors are running, or if the

compressors are running at maximum

capacity. These contact closures may be

used to trigger jobsite supplied alarm

lights or alarm bells.

performance by taking the corrective

action necessary to avoid shutdown.

This keeps cooling capacity available

until the problem can be solved.

Whenever possible, the chiller is allowed

to perform its function; make chilled

water. In addition, microcomputer

controls allow for more types of

protection such as over and under

voltage. Overall, the safety controls help

keep the building running and out of

trouble.

Options

Low Temperature Brine

Remote Evaporator

The remote evaporator is available as a

standard option.

Low Ambient Option

The unit controls can be factory set to

handle low temperature brine

applications (0°F to 39°F).

The low ambient option consists of a

variable speed drive on the first fan of

each circuit and special control logic to

permit low temperature operation.

This option provides an easily installed,

pre-engineered method of installing the

evaporator remotely indoors.

The remote evaporator is skid-mounted

and is shipped separately from the

outdoor (condensing) unit. Refrigerant

accessories, including electronic

expansion valve, moisture indicating

sightglass and removable core filter

drier, are shipped with the evaporator

skid. All refrigerant connections are

routed to one end of the evaporator skid

for easy connection. All electrical wiring

is factory installed and routed to a

terminal box (entering and leaving water

temperature sensor, evaporator

refrigerant temperature sensor and

electronic expansion valve control

wiring). Suction refrigerant temperature

sensors (two) must be field installed in

the field suction line piping next to the

evaporator connections.

Ice Making

The unit controls can be factory set to

handle ice making for thermal storage

applications.

Low Ambient Lockout

A factory installed ambient sensor and

control logic can prevent starting below

the recommended temperature.

Building Automation System

Communication Interface

Permits either bi-directional

communication to the Trane Integrated

Comfort^™system or permits remote

chilled water setpoint and demand

limiting by accepting a 4-20 mA or 2-10

Vdc analog signal.

Non-Fused Power Disconnect Switch

A non-fused disconnect switch with a

through the door handle is provided to

disconnect main power.

Circuit Breaker

A standard interrupting molded case

capacity circuit breaker (UL approved) is

available. The circuit breaker can also be

used to disconnect the chiller from main

power with a through the door handle

and comes pre-wired from the factory

with terminal block power connections.

Remote Display

In addition to controlling chiller

operation from remote location, the

remote display shall provide the

capability to monitor unit alarms and

diagnostics. Only one twisted pair is

required between the chiller and the

remote display .

Neoprene Isolators

Isolators provide isolation between

chiller and structure to help eliminate

frequency transmission. Neoprene

isolators are more effective and

recommended over spring isolators.

Chilled Water Reset

This option provides the control logic

and field installed sensors for either load

based (return water temperature) or

temperature based (ambient or zone)

reset of leaving chilled water

temperature (requires Communication

Package).

Spring Isolators

Spring isolators help isolate the chiller

from the building structure.

Condenser Corrosion Protection

Copper fins and CompleteCoat are

available on all size units for corrosion

protection. Job site conditions should be

matched with the appropriate condenser

fin materials to inhibit coil corrosion and

ensure extended equipment life. The

CompleteCoat option provides fully

assembled coils with a flexible dip and

bake epoxy coating.

Architectural Louvered Panels

Louvered panels cover the complete

condensing coil and the service area

beneath the coils.

Coil Protection

Louvered panels which protect the

condenser coils only.

Access Protection

A coated wire mesh which covers access

area underneath the condenser coils.

Convenience Outlet

Provides a 15 amp, 115 volt (60 Hz)

convenience outlet on the unit.

Control Power Transformer

This option eliminates the need to run

separate 115 volt control power to the

unit. A control power transformer is

factory installed and wired. A separate

115 volt power source is required for

60 Hz heat tape.

when others would shut down.

• Fewer nuisance trips means less

expense from unnecessary service

calls.

• Factory installed and tested options

keep start-up time and expenses

minimized.

• Easy interface capability with the Trane

Integrated Comfort^™system via a

single twisted pair of wires.

• Optional remote display panel

simplifies chiller monitoring/ control.
