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.

• The Elektronikon® controls both the compressor and the integrated converter, ensuring maximum machine safety within parameters.
• Flexible pressure selection with VSD reduces electricity costs.
• Specific converter and motor design (with protected bearings) for the highest efficiency across the speed range
• Electric motor specifically designed for low operating speeds with clear attention to motor cooling and compressor cooling requirements
• All Atlas Copco VSD compressors are EMC tested and certified. Compressor operation does not influence external sources and vice versa.
• Mechanical enhancements ensure that all components operate below critical vibration levels throughout the entire compressor speed range.
• A highly efficient frequency converter in a cubicle ensures stable operation in high ambient temperatures up to 50°C/122°F
• No ‘speed windows’ can jeopardize the energy savings and the stable net pressure. Turndown capability of the compressor is maximized to 70-75%.
• Net pressure band is maintained within 0.10 bar, 1.5 psi.
