55KW ATLAS OIL-FREE WATER INJECTED SCREW COMPRESSORS AQ55 VSD
POWERFUL OIL-FREE AIR
When it comes to clean, oil-free compressed air, you cannot afford to compromise on quality. Over the past decades, Atlas has pioneered
oil-free water-injected screw technology, resulting in a broad range of compressors delivering 100% oil-free, clean air. Setting the standard through
ISO 8573-1 CLASS 0 certification, the AQ meets your need for pure oil-free air while offering best in class energy efficiency.
Water-injected screw element
• Highly energy-efficient thanks to low temperatures.
• Water-lubricated, grease-free bearings.
• In-house design and manufacturing.
• Working pressure up to 13 bar.
Heavy-duty air filter
• Protects the compressor components by removing 99.9% of dirt particles down to 3 microns.
• Differential inlet pressure for proactive maintenance while minimizing pressure drop.
Water filter
• Ensuring a constant supply of clean water.
• The filtration capability equals 10 micron throughout the filter’s lifetime.
Integrated highly efficient dryer
• Excellence in air quality.
• 50% reduction in energy consumption compared to traditional dryers.
• Zero ozone depletion.
Elektronikon ® Graphic
Advanced Elektronikon ®Graphic control and monitoring system, designed for integration in a (remote) process control system
Air-cooled fan and water-cooler
• Air and water-cooled variants are available throughout the range.
• Small footprint and installation thanks to built-in heat exchangers.
• Water-cooled units provide a continuous air temperature at the dryer inlet of less than 55°C (131°F).
Electronic no-loss water drain
• Ensures constant removal of condensate.
• Manual integrated bypass for effective condensate removal in case of power failure.
• Integrated with compressor’s Elektronikon ® with warning/alarm features.
PROVEN TECHNOLOGY
At the heart of the new AQ range is a unique water-injected screw element working highly efficient near isothermal compression. The polymer ceramic rotors with their optimized rotor profile are supported by water-lubricated bearings, ensuring that no oil whatsoever can contaminate the compression element, thereby producing pure oil-free air.
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 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 offers the widest range of integrated VSD compressors on the market. In almost every production environment, air demand fluctuates depending on different factors such as the time of the day, week or even month. Extensive measurements and studies of compressed air demand profiles show that many compressors have substantial variations in air demand. Only 8% of all installations have a more stable air demand.
On average 35% energy savings Atlas ’s AQ VSD technology closely follows the air demand by automatically adjusting the motor speed. This results in on average 35% energy savings. The lifecycle cost of a compressor can be cut by an average of 22%. In addition, lowered system pressure with AQ VSD dramatically minimizes energy use across your production. Total compressor lifecycle cost.
Why Atlas Variable Speed Drive technology?
• 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).
