• The rotating part is made by high-
strength cast iron. It forms a closed
compression chamber, prevents the
deformation and the leakage, ensures
the high performance and prevents the
compressor from the hammering.
• 3-D scroll compressor has been
researched and improved for more than
20 years. The measurements and the
performance of more than 400,000 hours
have proved its high performance and
outstanding quality.
Outstanding and Reliable
Performance
• High part load efficiency, reduce power
consumption and save energy.
• Low sound level, applicable to high
standard requirement buildings.
• Chillers are tested before shipment,
ensure the safety and the reliability.
• Able to operating within 43˚C ambient
temperature.
• Specially designed electrical control
panel and colored cables for easier
connection. An attached strainer can be
installed on site by customers to prevent
the evaporator from clogging. Removable
panels make it easy to install, adjust and
maintain.
• The structure is compact and low in
height. It can be installed with clearance
of 1 meter to wall and chiller design
blends in well with most building
environment.
• Water flow protection system is included
as a standard component thus eliminating
installation of water switches on site.
• The dry contacts are provided by the
chiller to control the chilled water pump.

High efficiency 3-D Scroll
Compressor
The compressor of the chiller is 3-D scroll
compressor, which combines the 25
patents of "TRANE" together with
advantages of:
• Compared with the reciprocating
compressor of the same capacity, 3-D
scroll compressor reduced 64%
components, thus decreases frictions
and improves reliability and efficiency.
• The compressor torque variation is 30%
that of the reciprocating compressor with
the same capacity, thus reduces
vibrations and noise.
• The motor is cooled by the suction gas,
thus prolongs the service life, improves
the efficiency.
• Enclosed design, free of maintenance.

Features andBenefits
Powerful Microprocessor
SMM
• Leaving chilled water temperature
control
A water temperature sensor is fixed at
the outlet of evaporator. With this
temperature information, the SMM
module uses proportional integral
differential (PID) algorithm to predict and
control the on/off combinations of
sequencing compressors, thus controlling
the leaving chilled water temperature.
• Condensing pressure control
The SMM module can control the number
of operating condenser fans to achieve
the best of coefficient of performance
(COP), and to avoid the frequent chiller
shut down caused by the high/low
pressure protection.
• Performance optimization
In order to reduce electricity consumption,
the SMM module can automatically adjust
the chilled water setpoint in relation to
the outdoor temperature.
• Operator interface
The SMM module inc ludes a
communication interface with a liquid
crystal display. It helps technician to
access chiller operating conditions and
diagnosis information, thus making
operation and maintenance much easier.
• Remote control
The dry contacts and the analog inputs
are provided by the SMM module to
remote control the start/stop of the chiller
and to adjust the chil led water
temperature setpoint.
• Connection to the Building
Management System (BMS)
By option of TCI-S Communication Card
and serial communication cables, the
SMM module can communicate with the
professional BMS and in turn put the
chiller system under BMS group control,
so as to achieve operation and
maintenance convenience.
Environmentally Responsible
R407C Refrigerant
Both Aquastream cooling-only and
reversible chillers have been optimized
for exclusive use of chlorine-free R407C
refrigerant. Aquastream chillers operate
with a refrigerant that has a future and
complies with current and upcoming
environmental regulations.
Value Added Hydraulic
Module (Optional for models
040 to 080)
Only a main power supply & water
connections are necessary, the rest is
in the "box" such as pump, expansion
tank, valves, relief valve, water make-
up system etc which reduces customer's
installation time. TRANE offers this
hassle-free package that also saves
installation, operational and maintenance
costs.
Additional Functions
• Delay protection prevents the
compressors from frequent start/stop.
• Self-start after power off
• Self-balance the operation time of each
compressor
• Control the chilled water pump operation
• Prevent the evaporator from frosting
• Safety and protection operation
Standard Components
• Vibration proof rubber pad
• Y-type water strainer
• Differential pressure type water flow
switch
• Remote on / off switch
Options
• Condenser protecting grille
• Main power disconnect switch
• Compressor sound attenuator
• Factory installed low ambient
temperature kit.
• Integrated hydraulic module (Only for
040, 050, 060, 080 models)
Factory Testing and Quality
Assurance
• All chillers are subject to the strict
performance tests before shipment
• The Quality Management System
applied by "TRANE" factories in China
has been assessed and approved to ISO
9001 by professional organization.

The cooling capacity table in the chapter
of "general data" represents of typical
leaving water temperature under the
following conditions:
• Fouling factor = 0.086m2 • ˚C/kW
• Evaporator entering and leaving water
temperature difference between 4~8˚C.
Take CXAH as an example, the following
design conditions should be determined:
Cooling:
1) System cooling load(kW)
2) Chilled water leaving temperature(˚C)
3) Ambient temperature(˚C)
Heating
1) hot water leaving temperature(˚C)
2) ambient temperature(˚C), dry bulb(DB)
and wet bulb(WB) temperature.
Calculate the water flow rate with the
following formula:
Flow rate(L/s) = 0.239xload(kW)/entering and
leaving water temperature difference (˚C)
Case study for selection procedure
Cooling Conditiong:
Condition:
1) system load: 120 kW
2) chilled water leaving temperature:+7˚C
3) chilled water entering temperature:+12˚C
4) ambient temperature: 35˚C
1. Select model
According to the cooling capacity chart,
model CXAH050 can provide 125 kW
cooling capacity, and 39.5 kW input
power is required.
2. Water flow rate
Flow rate(L/s)=125x0.239/(12-7)=5.97(L/s)
3. Water pressure drop across evaporator
According to the water pressure drop
chart, when the flow rate is 5.97 L/s, the
pressure drop is 50 kPa for CXAH050.
Heating Condition:
Condition:
1) hot water leaving temperature 45˚C
2) ambient temperature: 7˚C(DB), 6˚C(WB)
1. According to the heating capacity
chart, model CXAH050 can provide 133
kW heating capacity, and 43 kW input
power is required.
2. The entering and leaving water
temperature difference can be calculated
by the following formula:
hot water entering and leaving
temperature difference= heating capacity
(133kW)x0.239/ water flow rate(5.97 L/s)
= 5.32˚C.
