Низкотемпературный ( 5C/ 15C) винтовой водяной охладитель с воздушным охлаждением (мощность охлаждения 50 950 кВт)

Product Overview

Description

 Air cooled screw water chiller

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. Trouble-free operation over 100000hours.

 

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, favourable thermal radiation.

 

7.Heat exchanger has the national pressure vessel certificate.

 

8. 16 years experience

 

9. Accept orders for special requirements.

 

10. Use PLC microcomputer control from Germany Siemens LCD touch screen, both English and Chinese human-machine interface.

 

11. Fluoride-resistant high-performance motor from French.
