Atlas Copco Extends GA VSD+ Range Of Rotary Screw Compressors
Atlas Copco Compressors has extended the GA VSD+ range of oil-injected rotary screw compressors through 50 hp.
The GA VSD+ range reduces energy consumption by up to 50 percent and increases free air delivery by up to 13 percent, compared to a traditional load/unload compressor of the same type. 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 Elektronikon controller, the cycle prevents condensation in compression oil, even in extremely low load conditions.
With a patented motor that exceeds the latest NEMA Premium efficiency requirements, the GA VSD+ range features a motor and drive train that share a single drive shaft and are vertically aligned, reducing the total footprint by up to 55 percent. The motor drive train 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. 800.732.6762, atlascopco.com
