why use two-stage compression?
many customers have special requirements for reducing energy consumption, high reliability and low maintenance costs. we use lowcompression ratio to achieve energy savings.
two-stage compression is unique technology in the market, which design and manufacture specially for the customers who requireshigh-tech and energy saving.
the feature ofair end：
l  two independent compression stages within a same frame.
l  larger rotors run at lower speed, and the displacement increases by nearly 15% compared with single-stage compression.
l  low speed of air end.
the advantage of coolant jet curtain：
l  uniform lubrication
l  high-efficient dynamic cooling
theadvantage of two-stage compression:
l  compression ratio stepped down in each stage
l load on bearings is small
l  the air end’s service life is two times of singe stage compression.
