The world's first CO2 two-stage rotary compressor
At the heart of the CO2 ECO Heating System is SANYO’s innovative rotary two-stage compressor system, a world first in compressor design. The compressor is resistant to high working pressure differentials, has high reliability through load dispersion, low leakage and low vibration. It operates at a quiet 45 dB(A) sound level and, at only 9kg, the compressor is compact and lightweight.
