Today, members of Atlas Copco’s global product team launched the new GA VSD+ range in Charlotte, N.C., to an invited audience of partners, distributors and representatives from across the United States. The new GA VSD+ range of compact, oil-injected rotary screw compressors can reduce energy consumption by 50 percent compared to a traditional load/unload compressor of the same type. The new 7-15 kW (10-20 hp) GA VSD+ range, including a full feature version with an integrated dryer, is also 15 percent more efficient than the previous generation and offers a 12 percent improvement in free air delivery.

 “Reflective of Atlas Copco’s drive for innovation, the new GA VSD+ is the next evolution in energy-efficient compressor technology,” said Robert Eshelman, vice president, Atlas Copco’s Industrial Air Division in the United States. “We have achieved many significant milestones during the past 19 years in rotary screw technology and our new design with patented features represents one of the largest and most innovative changes to the technology since 1994.”

The new range was designed with energy efficiency and customer needs in mind, with a motor that significantly exceeds the latest NEMA Premium efficiency requirements. Built upwards, like a mini skyscraper, the motor and drive train share a single  drive shaft and are vertically aligned, reducing the total footprint by up to 55% compared to other compressors on the market. In addition, the motor drive train is completely enclosed, resulting in a NEMA 4 rating for protection against dust, debris and water. A single closed oil-circuit cools the motor and lubricates the element and bearings, resulting in a very reliable and compact compressor that is also extremely quiet (down to 62 dBA).

The result is a revolutionary air compressor that saves space and energy while simultaneously achieving higher air capacities. Additional improvements include a more efficient fan, a robust air intake system that eliminates blow-off losses and advanced electronic components.

“The new GA VSD+ achieves better performances at full load than a comparable load/unload compressor, allowing customers in most industries to switch to a variable speed drive compressor for virtually any application, ultimately reducing energy costs and contributing to a more sustainable industry,” added Eshelman.

The new 7-15 kW (10-20 hp) GA VSD+ range, including a full feature version with an integrated dryer, is available now and stocked in the United States at Atlas Copco’s state-of-the-art 150,000 sq-ft. North American Service Center in Charlotte, N.C. The new 18-37 kW (25-50 hp) GA VSD+ models will be available in November 2013.
