The two-stage compression screw air compressors of Kaishan reach the key points of Level-1 energy efficiency:

KAITAIN JN Two-stage Compression Screw Air Compressor

1. Two-stage compression is closer to the most power-saving isothermal compression than single-stage compression. In principle, two-stage compression saves 5-8% more energy than single-level compression.

Adopting two-stage compression main engine means adopting two sets of SKY screw rotors of different sizes to achieve reasonable pressure distribution and reduce the compression ratio of each compression. Low compression ratio also has two special advantages: 1) reducing internal leakage, and promoting volume efficiency; 2) considerably reducing the load of bearings, promoting the service life of bearings and extending the service life of main engine.

2. World-leading efficiency of rotor molded lines

The most crucial is the efficiency of rotor molded lines, "T" patent molded line developed by Dr. Tang Yan, selected into Recruitment Program of Global Experts, with world-leading efficiency, 5-15% higher than other molded lines.

3. High-level configuration and system optimization

The key points also lie in the local design and details of products, and high-end system configuration and optimization, again 5-8% higher than the efficiency of other brand products.

Highly-efficient main engine and intrinsic air inlet conditioning design, cooling flow-field design, oil-gas separation technology, highly-efficient motor, intelligent automatic control and other innovative technology of JN series, will bring tangible energy-efficient benefit to customers.
