Condenser Coils
DC Inverter Rotary
1Compressor Motor
The unit adopts full DC inverter rotary
compressor, driven by high-efciency
permanent magnet DC motor to improve
the energy efciency greatly. The high-
efciency oil supply and oil separation
parts ensure the low friction, low noise,
stable and reliable operation of the
compressor.
Low sound power level EC fans,
together with high efciency DC inverter
motor,greatly reducing the power
consumption. Special 0-91Hz stepless
variable frequency speed regulation
ensures the stable and reliable operation
of the unit.

High efcient parts and unique design ensure the chiller high efciency COP up to 3.0.
Compact design, small footprint
‘Y’ shape design , small oor area, only 1.56m2,
28% footprint can be reduced.
Modular design, exible combination
The unit adopts modular design, and max.16 modules can be combined in each group, which can meet the load
demand of different buildings. The combination can be "full inverter units solution" or “inverter units and fixed
speed units solution”.

Precise temperature control
EXV adopts PID control, accurate control refrigerant distribution, outlet water temp. ±5% of the set temperature .
Quick start
With new inverter technology, quick start within 5s, maintain ultra high frequency operation within 1 hour to ensure
the room temperature can reach the set temperature as soon as possible.

Quick start, hyper
cooling and heating
The system will record the operating state before
the power cut. When the power supply is restored,
the system will automatically return to the state
before the power cut without setting again.
Power cut memory function
Shell & tube heat exchanger
The new modular chiller adopts shell & tube heat
exchanger(65/100/130kW) avoid dirty plugging,
higher efciency and reliability.
2.5 High Reliability
Filter drier
Filter drier,absorb moisture in the system, avoid the
emergence of the "ice block"
Pressure sensor control
Through the pressure sensor real-time
monitoring, realize the system quickly, accurately
control, ensure the unit efcient and stable
operation
Three phase fan motor
Three phase fan motor,compared with one
phase fan motor low starting current, high
speed and more stable.

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.

Note: 1.Specications are based on the following conditions:
• (T1) Cooling: chilled water inlet/outlet: 12°C/7°C, and outdoor ambient temp. 35°CDB;
• (T3) Cooling: chilled water inlet/outlet: 12°C7°C, and outdoor ambient temp. 46°CDB;
• Heating COPH : warm water inlet/outlet: 40°C/45°C, and outdoor ambient temp. 7°CDB/6°CWB;
• Heating COPH
*: warm water inlet/outlet: 30°C/35°C
• Water side fouling factor: 0.018m2•°C/kW;
• 1m away in open eld(sound pressure).
2.Due to our policy of innovation, some specications may be changed without notication.
