1.4 Energy Saving
The inverter system’s capacity modulation range is from 30% to 100%, while MDS system’s capacity
modulation range is from 10% to 100%.
Quick response to the capacity modulation.
Min. power consumption is only 10% of the full load power consumption.
Compared to the inverter system, there is no power consumption of transducer.
Compared to the nominal capacity scroll system, it can save 20% energy consumption.
