Variable Speed Rotary Screw Compressors

Over 80% of a compressor’s lifecycle cost is taken up by the energy it consumes. Moreover, the generation of compressed air can account for more than 40% of a plant’s total electricity bill. To cut your energy costs, Atlas Copco pioneered Variable Speed Drive (VSD) technology in the compressed air industry. VSD leads to major energy savings, while protecting the environment for future generations. Thanks to continual investments in this technology, Atlas Copco offers the widest range of integrated VSD compressors on the market.


Why Atlas Copco Variable Speed Drive technology?


  • On average 35% energy savings during fluctuations in production demand with an extensive turndown range.
  • Integrated Elektronikon graphics controller – controls the motor speed and high efficiency frequency inverter.
