R22 Air-cooled screw chiller

Aubert air-cooled screw refrigeration with heat pump is mainly applied in Large and medium-sized central air-conditioning, industrial cooling, supply 12/7℃ cooled water.

1. The main international advanced

semi-closed screw compressor in which electric motor and compressor are organically integrated to ensure no leakage of the shaft sealing. 

2. Control programs for start and stoppage are applied to double or multiple compressors so as to balance the load and extend the service life of each component.

3. Several refrigeration circuits are provided for double or more compressors. When one circuit needs maintenance, other circuits can work properly as alternative circuits.

4. The compressor is started with unloading and decompression to avoid the impact to the power grid.

5. The vortex and propeller of the compressor is designed to ensure extremely low noise.

6. H/W structural design, favorable thermal radiation.

7. Heat exchanger has the national pressure vessel certificate.

8. 10 years experience: aubert has specialized in chiller field for 10 years.

1.Above parameters refrigerating capacity are based on the condensation temperature 50℃, evaporation temperature2℃, R134a Refrigerant, single compressor.
2. Our standard refrigerant is R22, and the environmental refrigerant such as R407c, or R134a are also available.
3. Multi-system chiller unit with 2, 3 or 4 piece of compressors can be acceptable.
