Take 37kW screw air compressor as an example, all efficiency values were recorded during experiamental tested and the annual pwer usage calculation were based on average operating time of 8,000 hours per annum BOREAS PM screw air compressor compared with external variable frequency inverter screw air compressor Energy-saving per annum: 236, 800-183, 520=53, 280 kW
Compare with normal power frequency screw compressor:
Differences between BOREAS Compressor's PM variable frequency screw air compressor and mains frequency screw air compressor.
Once an mains frequency screw air compressor deviates from its nominal working conditions, its efficiency will decline no matter how energy-efficient it is at nomial con Is, making it less efficient in energy. In contrast BOREAS Compressors PM variable frequency technology is able to adjust the motors rotating speed according to demand changes in the air volume, thereby regulating the volume of discharged air and allow the air cor to aintain high efficiency under any conditions for air usage. Compared with ordinary mains frequency screw air compressor, the PM variable frequency screw air compressor possesses obvious energy-saving advantages whenever there are changes in the air volume required for the system. In addition. the higher the fur the results will be more obvious, and overall energy-saving can be as much as 50%.
In addition, the regulation range of external inverters for ordinary screw compressor is from 40% to 100%. In other words, when the working condition deviates in excess of 60%, the external inverter will not be able to regulate the motor's rotating speed. In contrast, BOREAS Compressors PM variable frequency air compressor has a operating speed range of 15-100%,which means that even in the case of 85% deviation from working conditions. POWER-TECH Compressor's PM variable frequency air compressor can still function effciently.
