YORK OptiSpeed™ Variable-Speed Drive

Benefits of the YORK OptiSpeed Variable-Speed drive include:

  • Energy savings – With an OptiSpeed drive, annual chiller energy consumption and carbon dioxide emissions can be reduced by as much as 30%.
  • Increased electrical protection – automatically corrects chiller power factor to 0.95+ at full load and designed to reduce electrical current harmonic distortion.
  • Lower sound levels – Chiller operation is quieter when compressor speed is reduced.
  • Reduced wear – Soft-start characteristic minimizes driveline shock caused by inrush current.
  • Quick-turn restart – Allows for chiller restart is as little as 3 minutes.
  • Unsurpassed experience – Since 1979, more YORK variable-speed drives have been installed on chillers than all other competitors combined.
