---huali water cooled chiller major components

1. High efficiency and saving energy as compared with the dry-type, it will save 10%-15% energy.
2. Performance stable, low noise and durable as adopt hanbell screw-type compressor.
3. With high efficiency flooded shell and tube heat exchanges and compressor, structure of the units is very skill and the heat exchange capacity is very strong.
4. With advance throttle equipment, not only improving the efficiency, but also protracting the use life.
5. The quantity of compressor can be one or two, each compressor is independent refrigeration system.
Each other run independently. When the one is working, the other can be working or not.
