Driving down energy costs

• The GA Series’ superior screw elements are designed to give the optimum combination of maximum free air delivery for low energy consumption.
• The state-of-the-art compressor element is powered by Efficiency 1 class / NEMA EPAct electric motors, contributing to maximum compressor package efficiency.
• All other components surrounding the core element, such as the aftercooler and water separator, are designed using the latest computational fluid dynamics (CFD) techniques for minimum internal pressure drops.
• GA VSD (Variable Speed Drive) compressors automatically adjust the compressed air supply to the demand. Thus the considerable waste of energy caused by no load operation and oil vessel blow-off losses can be avoided.VSD compressors are able to operate in a narrow pressure band setting which reduces the overall system working pressure. With 80 – 85% turndown capability the GA VSD can reduce your energy costs by 35% on average resulting in 22% lower life cycle costs.
• The VSD-driven radial cooling fans deliver optimum cooling flow and reduced energy consumption in any conditions, through precise fan speed regulation.
• The optional Energy Recovery system can recover up to 94% of the compressor shaft power as hot water.
• The New GA compressors feature no-loss drains which eliminate the waste of compressed air that conventional drains create.
• The compressor’s oil separator features an innovative filter material that removes oil particles from the compressed air while minimizing pressure drops. The result is optimal air quality at the highest efficiency.
• Elektronikon® controller features the Atlas Copco DSS (Delayed Second Stop) function which minimizes the idling time saving you energy. It allows timer-based start/stop and dual pressure settings.
• The integrated compressed air treatment includes a refrigerant dryer with the built-in Atlas Copco Patented Saver Cycle Control mode that reduces energy consumption in light load conditions.
