The ultimate smart solution, driven by efficiency
Atlas Copco’s GA 30+ -90 compressors bring you outstanding sustainability, reliability and performance while minimizing the total cost of ownership. A choice of three premium compressor types (GA VSD, GA+ and GA) provides you with the compressed air solution that perfectly matches your requirements with clear value propositions. Built to perform even in the harshest environments, these compressors keep your production running efficiently
How GA VSD technology saves energy
Contact your local Atlas Copco representative for an audit of your compressed air system. A real-time measurement
simulation and audit report can be provided with recommendations for additional savings and sizing to meet your
compressed air needs.
VSD: Driving down your energy costs
Over 80% of a compressor’s lifecycle cost is taken up by the energy it consumes. Moreover, the generation of compressed
air can account for more than 40% of a plant’s total electricity bill. To cut your energy costs, Atlas Copco pioneered
Variable Speed Drive (VSD) technology in the compressed air industry. VSD leads to major energy savings, while protecting
the environment for future generations. Thanks to continual investments in this technology, Atlas Copco offers the widest
range of integrated VSD compressors on the market.
Controls tailored to the needs of any workshop: the Elektronikon® I regulator is easy to comprehend and operate by anyone in the workshop using simple universal pictograms.
WHY ATLAS COPCO VARIABLE SPEED DRIVETECHNOLOGY?
On average 35% energy savings during fluctuations in production demand with an extensive turndown range.
- Integrated Elektronikon® Graphic controller controls the motor speed and high efficiency frequency inverter
- No wasted idling times or blow-off losses in normal 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).
