In addition to expanding the GA VSD+ range, with new models from 18-37kW, the company has also introduced its new “condensation prevention cycle” for Variable Speed Drive compressors. Thanks to an algorithm in the Elektronikon controller of the GA VSD+, condensation in the compression oil is prevented in all circumstances, even in those where the compressor is oversized for the application and has to deal with extremely low load conditions.
Atlas Copco claims that the integrated permanent magnet motor that drives the VSD+’s screw elements, contributes to realising energy savings of 50% on average, compared to fixed speed models.
