⭐ Level 1 Energy Efficiency Certified
Two-stage compression compared to single-stage compression, the two compression tends to the most provincial power of the isothermal compression. From the principle, the single-stage compression of the two compression energy saving 5~8%.
🏆 Won the award of Level 1 Energy Efficiency Grade Certification.
• Save 10%–15% energy vs. Level 2 Energy Efficiency Grade.
• Save 20%–30% energy vs. Level 3 Energy Efficiency Grade.
- Adopt two-stage independent compression.
- The pressure ratio is equal over both stages as well as having a lower compression speed, which helps improve volumetric efficiency.
- Oil mist spray cooling is used between the stages to make the entire compression process close to isothermal compression and improve the compression insulation efficiency.
- The two-stage rotors are directly driven by the bevel gear respectively, and the compression transmission efficiency is high.
- The large diameter and low speed of the rotors reduce stress on the bearings, thus lengthening their life span as well as any other components.
