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.  Installing a VSD compressor will lead to 30 – 50% energy savings, while protecting the environment for future generations.

There are many other benefits to choosing Variable Speed Drive technology such as:

  • A VSD compressor can start/stop under full system pressure. There is no need to unload. This saves time and energy.
  • No idling time lost, no blow-off losses in normal operations.
  • Avoid peak currents at start up and therefore also the penalties of most electricity companies.
  • With a lower system pressure, system leakages are minimized.
