CGWP
Cooling Capacity : 61~352 kW
Water Cooled Cold Generator
With the cooling capacity ranging from 61-352kW, all the models
are designed with multiple scroll compressors, thus bringing less operating vibration and lower running noise.
• Scroll compressors and durable
system components designed by
Trane fully exhibits Trane’s leading
technology in the industry.
• At least 30% EER higher and 3~5 dBA noise lower than air-cooled
chiller under the same operating
condition, therefore applicable to
residential and especially to light
commercial environments.
• Dual refrigerant circuit design brings higher part load efficiency.
• Easy installation and small unit’s foot print
High Reliability
• Scroll compressor has 60%
• fewer parts and has only 30% of torque variation compared with
reciprocating compressor; thus has
longer lifecycles and more reliable
operation.
• Scroll compressor prevents the liquid refrigerant and dirt from coming
into the machine, thereby prevents
compressor damage caused by liquid
strike.
• Equipped with microprocessor
controller, it provides fully protective
functions and operation orientation.• Over ten thousand hours testing proved unit performance and high
reliability of the systems.
High Efficiency
• Scroll compressor features low
friction loss and high efficiency.• Designed with multiple scroll
compressors, the unit can achieve
outstanding efficiency at part load
operation.
Safe and Reliable
• Water-proof design enables unit to be installed outdoor to meet
customers’ specific requirement.• Flat top surface prevents water
droplets from getting into the unit.• All electrical components used
waterproof design for operating
pressor
Hermetic scroll compressor features high
EER and low operating noise. Each
refrigerant circuit can operate individually
and switch over according to the loading
demand, hence can extend operating life
of the machine.
Condenser
Seamless external enhanced copper tube
in shell design, refrigerant side is tested
at 28.7kg/cm2 (420psi) and 15kg/cm2
(220psi) for waterside.
Evaporator
• 020~060
Compact size of brazed plate type
heat exchanger with antifreeze
protection allows the system to run
more stably. 80-mesh Y-type strainer
provided by the factory must be
installed in the water inlet to prevent
water circuitry to be blocked at
jobsite.
• 080~120
The unit uses seamless internal
enhanced copper tube in shell
design. A 4” flange type strainer
provided by the factory must be
installed in the water inlet to prevent
water circuitry to be blocked at
jobsite.
Enclosure
• Powder painting enclosure, free of
rust for longer period of time than
normal treatment.
• Deform free frame design and
symmetric internal layout.
• All panels are removable to facilitate
maintenance.
• Cooling or heating (80-120 only).
• Memory setting function.
• On/Off timer.
• Compressor re-start protection and delay
startup.
• Compressor high/ low pressure cutout,
overload protection.
• Compressors sequential startup Self
diagnosis and codes display.
• Working status display (water temperature
and refrigerant pressure etc.)
• Either inlet or outlet water temperature
control.
