VSD: Driving down your energy costs
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 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 offers the widest range of integrated VSD compressors on
the market.

Why Atlas Variable Speed Drive technology?
• On average 35% energy savings during fluctuations in production demand with an extensive turndown range.
• Integrated Elektronikon Touch controller controls the motor speed and high efficiency frequency inverter.
• No wasted idling times or blow-off losses in normal operation.
• Compressor can start/stop under full system pressure without the need to unload with special VSD motor.
• Eliminates peak current penalty during start-up.
• Minimizes system leakage due to a lower system pressure.
• EMC Compliance to directives (2004/108/EG).

In almost every production environment, air demand fluctuates depending on different factors such as the time of the day, week or even month. Extensive measurements and studies of compressed air demand profiles show that many compressors
have substantial variations in air demand. Only 8% of all installations have a more stable air demand.
