Advantages of BOREAS Compressor’s PM variable frequency screw air compressor

Once an mains frequency screw air compressor deviates from its nominal working conditions,its efficiency will decline no mater how energy-efficient it is at nominal conditions,making it less efficient in energy. In contrast BOREAS Compressors PM variable frequency technology is able to adjust the motor's rotating sped according to demand changes in the air volume,thereby regulating the volume of discharged air and allow the air compressor to maintain 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 fluctuation the results will be more obvious,and overall energy-saving can be as much as 50%.
Ordinary screw air compressors can regulate the motor's rotation speed through external inverters to regulate the air discharge volume in order hat air volume produced matches that of used and hence achieves energy efficiency. However ordinary screw air compressors are built with motors with mains rated rotating speed,rated power and rated efficiency,Whereas external inverters would force the air compressors motor to deviate from its mains rated rotating speed.Once the ordinary motor deviates from its mains rated rotating speed,its efficiency will be reduced significantly,and the greater the deviation the more significantly the efficiency will be declined.
A high-efficiency PM variable frequency screw air compressor has advantages in the following three areas:
1.The first is to have a highly efficient screw compression unit; 2. Secondly to have a high-efficient PM synchronous motor;
3. Thirdly to have first-class PM variable control technology.
BOREAS PM Variable frequency air compressor possesses significant technical advances in the following three areas.
In addition, compared to the ordinary PM variable frequency screw air compressors, BOREAS PM Variable frequency screw air compressors have obvious technological advantages in the three aspects including screw compression unit efficiency,motor efficiency, and control technology.
