500kW 150 tons Industrial Air Cooled Screw Chiller with Bitzer Compressor

Compressors

1. Screw Compressor(Bitzer/Copeland/Hanbell) which is 20-30% more energy efficient than the general compressor.
2. This industrial chiller unit has obtained patents from many countries in Europe and America and has passed the ISO9001:2000 international quality certification.
3. Efficient 5:6 patent asymmetrical gear shape.
4. Capacity control can be four-stage (100%-75%-50%-25%) or three-stage (100%-66%-33%) and non-stage control system.
5. The combination design of 11 bearings and A-type axial thrust balancing drum greatly increases the bearing life by 2.5-3.5 times.
6. High-efficiency silicon steel plate with special groove design and omni-directional cooling flow to make the compressor motor perform at the highest efficiency under any load.
7. The unique built-in hydraulic system ensures the best lubricating effect of the compressor without oil pump.
8. Multiple refrigerant options. In addition to R22 refrigerant, environmentally friendly refrigerants such as R134a and R407c are also available.
9. All-round compressor capacity ratio (V1=2.2/2.6/3.0/3.5) can be selected, which can effectively avoid additional energy consumption due to compressor overload or insufficient compressor pressure.

Protection Devices
