Adopts advanced Frequency Converter Technology,with high efficiecny TOSHIBA/SANYO/HITACHI DC inverter type compressor.

High efficiency and energy saving (reach European energy Class A+, adopts advanced frequency converter technology The rotating speeds of the compressor are controlled by pulsed amplitude with a wider range of speeds In this way the refrigerant gas quantity pumped changes according to the room temperature, so reducing energy consumption and costs, keeping temperature at the desired level keep the room temperature comfortable constantly.Available capacity:9000btu,12000btu,18000btu,24000btu,9000btu x 2,12000btu x 2 and 9000btu+12000btu.
