Atlas Copco AQ 15-55 VSD Oil-free Water-Injected Compressors

Untreated compressed air carries moisture and aerosols that accelerate corrosion and lead to leaks in your air system, potentially causing equipment damage and product contamination. The resulting maintenance costs often far outweigh the investment in proper air treatment. Atlas Copco compressors deliver clean, dry air to enhance system reliability, prevent expensive unplanned shutdowns, and protect your product quality from compromise.

• Pressure dewpoint of 3°C/38°F (100% relative humidity at 20°C/68°F).
• Heat exchanger cross-flow technology with low pressure drop.
• Zero waste of compressed air thanks to no-loss condensate drain.
• Reduced operating costs.
• Environmentally-friendly characteristics; zero ozone depletion.
• Global warming potential has been lowered significantly by an average of 50% by reducing the amount of refrigerant in the new dryer.

The integrated refrigerant air dryer of the AQ VSD gives you a pressure dewpoint as low as 3°C/38°F, which means it can be used for applications that require IS0 8573-1 Class 4 air quality.

What is unique about the integrated Atlas Copco AQ VSD?

Equipped with Variable Speed Drive (VSD) technology, the AQ series automatically adjusts its motor speed to precisely match the fluctuating air demand in real-time. This intelligent operation results in significant energy savings, often reducing energy consumption by an average of 35% or more compared to fixed-speed compressors. By eliminating wasteful unloaded running periods and optimizing energy use, VSD technology directly translates into substantially lower operational costs and a reduced carbon footprint.

1.The Elektronikon controls both the compressor and the integrated converter, ensuring maximum machine safety within parameters.

2.Flexible pressure selection from 4 to 13 bar with electronic gearing reduces electricity cost

3.Electric motor specifcally designed for VSD operation (inverter duty motor). Bearings are protected against induced bearing currents. Both motor and converter are perfectly tuned for highest efciency across the entire speed range.

4.Electric motor specifcally designed for low operating speeds with clear attention to motor cooling and compressor cooling requirements.

5.All Atlas Copco AQ VSD compressors are EMC-tested and certifed. External sources do not infuence compressor operation, nor does the compressor afect the operation of other instruments via emissions or via the power supply line.

6.Mechanical enhancements ensure that all components operate below critical vibration levels throughout the entire compressor speed range.

7.A highly efcient frequency converter in a cool overpressure cubicle ensures stable operation.

8.No‘speed windows’that can jeopardize the energy savings and the stable net pressure. Turndown capability of the compressor is maximized

9.The cubicle cooling booster increases the lifetime of electrical components due to a cool cubicle in overpressure and reduced dust ingress.

10.Ofering precise control over pressure, a net pressure band is maintained within 0.10 bar, 1.5 psi.
