Atlas Copco boosts compressor range

Atlas Copco has added to its large screw compressor range with the new VSD models which offer improved flow and energy savings

There are three new models in its range of oil-injected rotary screw compressors which the company say will give larger industrial air users a 20% average improvement in free air delivery (FAD) and energy savings of up to 35%. The VSD additions comprise the GA200VSD, GA250VSD and an upgraded version of the GA315VSD, with three different pressure variants from 8.5 to 14 bar developed to match operators’ needs and they complement the existing fixed speed GA160+-315 range.
 
Their specialist design has improved airflow and users can select smaller compressors for the same applications, saving money and energy. Atlas Copco’s new generation asymmetric compression element, which is incorporated into these machines, has increased FAD by an average of 20% across the range.
 
With the use of variable speed drive technology, energy savings of up to 35% are achievable by automatically adjusting the motor speed to match the air demand. Additionally, the optional energy recovery system can recoup up to 75% of the compressor’s shaft power as hot water, which can be re-used for process operations or premises heating applications.
