VSD upto 35% Energy Savings

Atlas Copco’s GA Variable Speed Drive technology closely matches the air
demand by automatically adjusting the motor speed. This results in energy
savings of on average 35% compared to load/unload machines
Why choose Atlas Copco Variable Speed Drive technology?
• Integrated Elektronikon® Touch controller controls the motor speed
• Unique inverter design
• Oil cooled iPM motor means the compressor can start/stop under full system pressure without the need to unload
• Eliminates peak current penalty during start-up

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.
