The objective of a variable frequency drive within a screw compressor environment is to provide a cost effective solution for the customer with a varying air demand whilst maintaining a constant system pressure. The HPC SIGMA Frequency Control SFC) drive system is an evolution of the variable speed screw compressor revolution and represents the very latest advancement variable frequency drive technology.

In developing these screw compressors, particular consideration was given to avoiding any specially designed high speed drive motors and airends. Although these may reduce the initial purchase cost they can result in severe limitations on reliability, airend efficiency and component service life.

Rotary Screw Compressor

Developed and designed specifically to complement and enhance the range of HPC energy efficient rotary screw compressors, the unit combines SIEMENS AG drive technology with the unique HPC KAESER SIGMA profile airend and SIGMA Control system to provide outstanding performance characteristics. Large, low speed SIGMA profile airends deliver excellent performance over the whole of the controlled speed range ensuring unrivalled specific power ratings.

The efficiency of screw compressors that are speed controlled by a frequency inverter is not constant over their whole range of control and if variable speed compressors are wrongly used, they can turn into power eaters without the user being aware of this. The path to maximum energy efficiency is the correct application of screw compressor control systems. Applied in the correct circumstances and system configuration by Maziaks, the selection of an SFC variable frequency drive screw compressor can deliver significant additional energy and cost savings.

Screw Compressors Energy Saving Tips

  • Increasing stored air volume within a screw compressor system will reduce the cycle time of the screw compressor generation plant and subsequently reduce energy costs.
  • Create hot water for free by installing an ‘oil to water’ heat exchanger within an air screw compressor‘s cooling oil circuit and recover around 80% of the compressor‘s input Kw.
  • Correctly sizing distribution pipework within a compressed air system for a given factory demand or screw compressor output will reduce system pressure drop and in turn reduce energy costs.
  • Use an Interest Free unsecured loan from the Carbon Trust to fund the purchase of new, efficient compressed air equipment, improving business cash flow, gaining new capital plant, improving system reliability and reducing energy costs all in one hit.
  • ‘Oil Free’ compressors should only be used when there is absolutely no alternative and all other possibilities have been exhausted as they are, in general terms, at least 15% less efficient than oil cooled screw compressors.
