Two-stage compression technology
Two-stage compressor(or Dual-stage compressor) energy-saving 5%~13% over equivalent sized single-stage compressors. But why?
– Adopt two-stage compression to attain reasonable pressure distribution and reduce each compression ratio, which can achieve the compressor’s power savings.
In a single-stage compressor operating at 100 PSIG at sea level, the compression ratio is 7.9 to 1 (in absolute terms). But a two-stage compressor operating at the same pressure will have a compression ratio of 2.8 to 1 in each stage (2.8 is the square root of 7.9) .
– Low compression ratio reduces the internal leakage and improve volumetric efficiency.
– Low compression ratio reduces the bearing load, improve the bearing life and extend the life of the host.

Variable Speed Drive (VSD) Technology
– Why does Variable Speed Drive (VSD) save energy when compared to fixed speed?
Permanent Magnet Synchronous Motor
Permanent magnet synchronous motors are more efficient than The Asynchronous motors and have a wide high efficiency range:
– For the permanent magnet synchronous motor, when the speed range is 25% -99% of the rated speed, the efficiency can reach 95% -97%.
– But for the Asynchronous motor, only when the speed range is 70% -99% of the rated speed, the efficiency is about 88%. And what’s more, when the speed range is lower than 70% of the rated speed, the efficiency will drop sharply.
