Polar air-cooled chiller (with free cooling)

- Cooling capacity: 20KW-165KW.

- The unit uses a combination of Free Cooling fin heat exchanger and high-quality pipe transfer valves for efficient heat exchange and low ring temperature natural cooling.

- Modular design, flexible combination of a variety of models, multiple parallel can have the system balanced operation function, to ensure that the use of each compressor time is equal.

- The unit has been debugged before the factory, as long as the power supply is connected to the water system, you can start to use, extremely simple.

- Three modes, automatic switching:

Summer: The cooling mode of air-cooled chiller is used；

Transition season or transition period (compensation mode) : When the ambient temperature is lower than the chilled water temperature, the natural cooling system is started, and the refrigeration compressor runs as the compensated cold source, thereby reducing energy consumption；

Winter: when the outdoor temperature is lower than the return water temperature, the difference is to a certain extent, the refrigeration compressor stops running, and the outdoor cold air is completely used for direct cooling cycle, at this time, only the circulating power consumption of the fan pump is achieved to achieve the maximum energy saving.

- With RS485 standard interface, it is convenient for users to realize centralized control and remote monitoring of the unit.
