for 50% average energy savings*
Atlas Copco’s GA Variable Speed Drive
+
(VSD
+
) technology closely matches 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
reduction of 37% in the lifecycle cost of a compressor.
Why Atlas Copco Variable Speed Drive
+
technology?
• Onaverage50%energysavingswithanextensiveowrange(20-100%).
• Integrated Elektronikon
®
Touchcontrolsthemotorspeedandhigh-eciencyfrequencyinverter.
• Nowastedidlingtimesorblow-olossesduringoperation.
• Compressor can start/stop under full system pressure without the need to unload.
• Eliminates peak current penalty during start-up.
• Minimizes system leakage due to a lower system pressure.
• EMCcompliancetodirectives(2004/108/EG).
