ATLAS COPCO SETS A NEW
INDUSTRY STANDARD
When it comes to clean, oil-free compressed air for your critical processes, you can't afford to compromise. Atlas Copco, a pioneer in oil-free air screw technology, is known for its range of water-injected compressors designed especially for applications that require oil-free air. Now Atlas Copco has achieved a new milestone: setting the standard for air purity as the first manufacturer to be certified ISO 8573-1 CLASS 0.
Why a new class?
Industries such as pharmaceuticals, food and beverages, electronics and textiles must exclude any risk of contamination. Otherwise severe consequences could follow: spoiled or unsafe products, production downtime and damage to both brand and reputation.
To address the needs of critical applications where air purity is essential, the ISO 8573-1 compressed air standard was revised in 2001. Along with a more comprehensive measuring methodology, a new and more stringent class was added to the five existing purity classes: ISO 8573-1 CLASS 0.
First to achieve ISO 8573-1 CLASS 0
As the industry leader committed to meeting the needs of the most demanding customers, Atlas Copco requested the renowned TÜV institute to type-test its AQ range of oil-free water-injected screw compressors. Using the most rigorous testing methodologies available, all possible oil forms were measured across a range of temperatures and pressures.
The TÜV found no traces of oil at all in the output air stream. Thus Atlas Copco not only became the first compressor manufacturer to receive CLASS 0 certification, but also exceeded ISO 8573-1 CLASS 0 specifications.
Atlas Copco eliminates any risk
Only oil-free compressors deliver oil-free air. Whether your activities are in pharmaceutical production, food processing, critical electronics or a similarly exacting industry, it is essential to eliminate risk. That's why you need an Atlas Copco risk-free solution: oil-free screw compressors especially for applications demanding the highest levels of purity. Zero oil means zero risk. Zero risk of contamination. Zero risk of damaged or unsafe products. Zero risk of losses from operational downtime. Above all, zero oil means zero risk of ruining your hard-won reputation.
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.
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.
Why Atlas Copco 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).
What is unique about the integrated Atlas Copco AQ VSD?
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 costs.
3 Special electric motor specifically designed for VSD operation (inverter duty motor). Bearings are protected against induced bearing currents. Both motor and converter are perfectly tuned for highest efficiency across the entire speed range.
4 Electric motor specifically 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 certified. External sources do not influence compressor operation, nor does the compressor affect 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 efficient 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 Offering precise control over pressure, net pressure band is maintained within 0.10 bar, 1.5 psi.
