- Screw Compressor(Bitzer/Copeland/Hanbell) which is 20-30% more energy efficient than the general compressor.
- This industrial chiller unit has obtained patents from many countries in Europe and America and has passed the ISO9001:2000 international quality certification.
- Efficient 5:6 patent asymmetrical gear shape.
- Capacity control can be four-stage (100%-75%-50%-25%) or three-stage (100%-66%-33%) and non-stage control system.
- The combination design of 11 bearings and A-type axial thrust balancing drum greatly increases the bearing life by 2.5-3.5 times.
- 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.
- The unique built-in hydraulic system ensures the best lubricating effect of the compressor without oil pump.
- Multiple refrigerant options. In addition to R22 refrigerant, environmentally friendly refrigerants such as R134a and R407c are also available.
- 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.
