- Two-stage compression reduces the compression ratio of each stage, reduces internal leakage, improves volumetric efficiency, reduces bearing load, and increases the life of the main engine.
- Two-stage compression instead of single-stage compression, the exhaust volume increases by nearly 15%, which can achieve 15% more energy-saving effects.
- The rotor adopts the latest designed rotor patented profile. After more than 20 procedures, the precision, reliability and effectiveness of the rotor profile are guaranteed.
The two-stage compression main engine is more efficient and energy-saving. Compared with ordinary industrial frequency machines, it can save energy up to 35%. Calculated at 8000h/unit/year, it can save 200,000 yuan of electricity bills every year.
