Next-generation compressor offers up to 60% energy savings

| By Gerald Ondrey

The GS variable-speed drive (VSD) compressor (photo) can adapt and optimize its operations, thanks to “smart” features. The GA VSDS (photo) is the third generation of VSD compressors. VSD compressors significantly reduce energy consumption by adjusting their motor speed to the fluctuations in compressed-air demand. The new technology will be available first in the 30–50 hp (22–37 kW) GA oil-injected screw compressor range. In addition to its minimal number of components, the GA VSD is the first compressor to feature an IE5 ferrite-assisted synchronous reluctance motor, eradicating the need for the use of increasingly precious and rare earth materials. — Atlas Copco Compressors LLC, Rock Hill, S.C.
