Atlas Copco GA 7-75 VSD+ Oil-Injected Rotary Screw Compressor
50% average energy savings with variable speed drive technology
The Atlas Copco GA 7-75 VSD+ is an oil-injected rotary screw compressor with a unique vertical, low-footprint design. Unlike traditional horizontal compressors, the upright layout saves valuable floor space, eases maintenance access, and reduces the total cost
of ownership.
Atlas Copco's VSD+ technology automatically adjusts motor speed to match air demand. Combined with the integrated iPM (Permanent Magnet) motor, this delivers average energy savings of 50% and reduces lifecycle costs by an average of 37%.
The GA VSD+ covers a power range of 7-75 kW (10-100 hp) with a flow range of 20-100%. It can start and stop under full system pressure without unloading. There are no wasted idling times or blow-off losses. Peak current penalties during start-up are eliminated.
Lower system pressure also minimizes leakage across the compressed air network. The integrated Elektronikon Graphic controller manages motor speed and the high-efficiency frequency inverter. All units are EMC tested and certified to directive 2004/108/EG.
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.
