Atlas Copco has added its variable speed drive plus (VSD+) technology to its entire range of GA oil-injected rotary screw compressors. VSD+ is now available worldwide in all pack and full feature versions of GA compressors. The technology was previously only offered on the GA 7-37 models.
VSD compressors adjust motor and element speed to meet the demand of a plant or facility, making them ideal for applications with variable demand. Because they are only running at the minimum required speed, VSD compressors cut energy use and associated costs.
Atlas Copco VSD+ compressors offer further advantages, including an iPM (Permanent Magnet) motor, a new compression element and a sentinel valve, allowing them to deliver significantly improved energy savings. With free air delivery (FAD) and specific energy requirement (SER) both improved by 9%, customers get 9% more air while using up to 9% less energy than with first generation VSD compressors.
The GA VSD+ line provides a smaller footprint than traditional GA VSD compressors and produces low noise levels of only 67dB(a), making them ideal for a range of facilities and applications.
