double screw Air Cooled Screw Chiller,Finned type Air Cooled Screw Chiller

Description:

The series air cooled screw type chiller cooling capacity from 85KW to 1550KW. This series units integrates the characteristics of many other products, using imported semi-closed screw compressors,supplemented by high-efficiency heat exchangers and adopts microcomputer controllers, which makes the unit compact, reasonable layout, convenient to use and maintain. The user just need simply connect the pipeline of the water system and the required power supply,then can put into operation.

This series of chillers is widely used: it can provide process chilled water for industrial and mining enterprises such as textile, chemical and petroleum. The manufacturing technology of this product is mature and stable and reliable.

Features of chiller:

1. Environmental protection

2. Energy efficient

3. Adopt international brand compressor

4. The system stable and reliable.

5. Electronic expansion valve throttle, adjust the range more accurate.

6. Modular design of the unit, the free combination of up to 10 modules can be connected, any one can be set to be main module.

Safety system:

1 Compressor reverse protective

2 Freeze protector protective

3 Refrigerant safety valve

4 Buzzer

5 High-pressure gauge and Low-pressure gauge

6 Power phase failure protector

7 Coil over-heat protector

8 Temperature auto-switch

9 Refrigerant shortage protective
