Sonyo Compressor (previous Panasonic Dalian) successfully introduced AC inverter solutions to condensing unit market in 10 years ago, their AC inverter range scroll compressor gained good reputation in this segment market.

Nowadays, Sonyo compressor has upgraded their AC inverter range by new DC inverter solutions, the new DC inverter range includes 62cc, 84cc and 110cc scroll compressors, available for both medium temperature and low temperature applications. To improve the compressor efficiency and liquid resistance, a new vapor injection channel and a dynamic compression ratio valve are adopted in the compressor, and the new compressor is also featured with extremely low noise level thanks to the special noise reduction design.

In near future, Sonyo Compressors also plans to implement low GWP solutions for this DC inverter range, such like R454C and R455A refrigerants, which has been already widely applied in their fixed speed compressor range.
