Atlas Copco Compressors has extended the GA VSD+ range of oil-injected rotary screw compressors through 50 hp (37 kW). Launched in the United States in June 2013, the innovative and award-winning GA VSD+ range reduces energy consumption by up to 50% and increases free air delivery by up to 13%, compared to a traditional load/unload compressor of the same type.
“The GA VSD+ range was designed with energy efficiency and customer needs in mind, and with this extension, we can now offer VSD+ technology for 75% of the oil-injected screw compressor applications worldwide,” said Robert Eshelman, vice president, Industrial Air Division, Atlas Copco Compressors. “Customers in most industries can switch to variable speed drive technology, ultimately reducing energy costs and contributing to a more sustainable industry.”
With this extension, Atlas Copco is the first in the market to introduce a condensation prevention cycle for variable speed drive compressors. Integrated with the Elektronikoncontroller, the cycle prevents condensation in compression oil, even in extremely low load conditions.
“The GA VSD+ range is reflective of our drive for innovation and represents one of the largest and most innovative changes to rotary screw technology since we pioneered the variable speed drive in 1994,” said Eshelman. “We believe the future of industrial compressors is 100% variable speed drive and expect to see the continued adoption of variable speed drive technology across most industries.”
With a patented motor that exceeds the latest NEMA Premium efficiency requirements, the GA VSD+ range features a motor and drivetrain that share a single drive shaft and are vertically aligned, reducing the total footprint by up to 55% compared to other compressors on the market. The motor drivetrain is completely enclosed, resulting in a NEMA 4 rating for protection against dust, debris and water and the 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.
To make this innovative technology accessible to all compressor users, the VSD+ range is positioned in the U.S. market at the same price level as a standard variable speed drive model.
