GA 7-75 VSD+ (7-75 kW/10-100 hp)

Atlas Copco has turned the compressed air industry on its head by redesigning the conventional layout of a typical air compressor. Instead of the normal space-taking horizontal design, the new GA 7-75 VSD+ has an upright, vertical, low footprint layout. This saves valuable floor and work space, eases maintenance access, accelerates manufacturing time, and reduces the total cost of ownership for all customers.

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

• 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).
• Compared to fixed speed compressors, based on measurement performed by an independent energy audit agency.
