VSD+ FOR 50% AVERAGE ENERGY SAVINGS*
Atlas Copco’s GA Variable Speed Drive+ (VSD+) technology closely follows the air demand by automatically
adjusting the motor speed. Combined with the innovative design of the iPM (Permanent Magnet) motor,
this results in average energy savings of 50% and an average cut of 37% in the lifecycle cost of a compressor.
VSD+ works with permanent, in-house designed magnet motors.
Why Atlas Copco Variable Speed Drive+ technology?
• On average 50% energy savings with an extensive flow range (20-100%).
• Integrated Elektronikon® Graphic controller controls the motor speed and high efficiency frequency inverter.
• No wasted idling times or blow-off losses during 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).
