protection, high/low pressure protection, over
currency protection and reverse protection, etc..
Air cooling side heat exchanger
By using calculation model and acquiring heat
exchanging ratio to optimize the windward air
speed and condensation temp.
Motor
Low sound power level axial fan, together with
the high efcient motor, making higher efciency
and lower sound power level.
EEV
High efcient EEV (thermostatic expansion
valve) to adjust the overheating degree of
system to control refrigerant volume. High
efcient evaporator to make part load and full
load COP the highest.

High efciency system
The new series adopt more high efcient parts and unique design ensure the chiller high efciency EER up to
3.4.COP above 3.4 (R410A Series).
High Reliability
Backup operation function
The system has three modules, the actual operation of just two module, if one module malfunction another module
will start automatically according to the water temperature.

overload protection, etc.
Pressure sensor control
Through the pressure sensor
real-time monitoring, realize the
system quickly,
accurately control, ensure the unit
efcient and stable operation.
Filter drier
Filter drier,absorb moisture in the
system, avoid the emergence of
the "ice block"

Modular design
Max 1040 kW with 16 modules, exible
combination, more convenient for
design and transportation.
Standard of water lter
Standard of water lter prevent the
destruction of the impurities in water

2.2 Technical Features
2.2.1 The modular design, capacity can be broadened.
The unit uses modular design module, a plurality of modules are connected together, the unit can be connected
to 16 separate unit module, can be done to expand the width capacity between 65kW-1040kW; at the same time
each individual module no distinction between them, both it can be used as a host; also be used as auxiliary use,
high design and installation exibility.
2.2.2 A combination of convenience, balanced operation, automatic control.
When module combination, water pipe and communication line need to connect to each other. The advanced
microcomputer control system will automatically achieve uniform load distribution unit, so the unit is always in
the best operating condition, and does not consume unnecessary energy. While for the whole unit, the system
running time is basically same which can increase the overall life of the unit and operate at low load in some
modules.

2.2.3 Efcient intelligent control
Features:
Ability autoregulation
Linkage centralized control technology
Self-diagnostic technology
Lock function
Winterized function
With a strong self-protection and self diagnostic functions:
Compressor high and low voltage protection, power supply reverse (lack of) of protection, frost protection in
cooling mode, the unit frost protection in winter water systems, compressor overcurrent protection, compressor
discharge temperature protection, anti-overheating protection, ow switches protection, sensor fault protection.
2.2.4 Environmental protection:
R410A refrigerant, higher cooling (heating) efciency. Improve air conditioning performance, do not damage the
ozone layer.
2.2.5 Ultra-wide operating range
50 degrees in ultra-high temperatures cooling, but also can meet the ultra-low temperature of minus 15 degrees in
heating operation.
2.2.6 Low noise:
World-class scroll compressor, low noise fan, low noise operation.
2.2.7 Precise throttle mode:
Reliability using electronic expansion throttling way to ensure the system.
