Southern Cross VSD compressors use the renowned Schneider Altivar 61 Variable Speed Drive.

  • Efficient and reliable
  • Worldwide support


  • Direct drive (1:1 ratio) motor and airend operate at low speed.
  • Gradual increase in motor speed eliminates starting spikes and cost penalties.
  • A steady system pressure is maintained lowering system stress and overall air demand.
  • Reduced air leaks due to lower operating pressures.
  • Significantly lower noise levels.
  • Environmentally friendly energy savings.

Variable Speed Drive

A variable speed controller enables the air compressor to exactly match demand eliminating the high part load energy usage experienced with fixed compressors.

Imagine an intelligent rotary screw air compressor that can accurately and rapidly vary it’s output to match your changing demand with corresponding reduction in absorbed power.

More than 70% of the long term cost of owning an air compressor can be attributed to energy usage. Over the life of the compressor, this adds up to many times the original investment, yet in many cases, much of this energy is wasted through part load control.
