The New Revolutionary Compressor From Atlas Copco

With its innovative vertical design, Atlas Copco’s GA 7-75 VSD brings a game-changing revolution in the compressor industry. It offers Variable Speed Drive as standard, a compact motor and footprint thanks to its in-house design and iPM (Permanent Magnet) technology. The GA 7-75 VSD reduces energy consumption by on average 50%, with uptimes assured even in the harshest operational conditions. The GA 7-75 VSD is the air compressor of the future, designed in-house by Atlas Copco. It will set a new standard for years to come, positioning Atlas Copco as a leader in the compressed air industry

Vsd + Fof 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 cut of 37% in the lifecycle cost of a compressor. VSD+ works with permanent, in-house designed permanent magnet motors.

A STEP AHEAD IN MONITORING AND CONTROLS

The next-generation Elektronikon® operating system offers a great variety of control and monitoring features that allow you to increase your compressor’s efficiency and reliability. To maximize energy efficiency, the Elektronikon® controls the main drive motor and regulates system pressure within a predefined and narrow pressure band.

VSD+ works with permanent, in-house designed permanent 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).
