Compressor Anti-surge Control

Compressor Control

  • Compressor start and stop
    The inlet valve and blow-off valve are controlled efficiently.
  • During steady-state operation
    The inlet valve is controlled to regulate the blow-off flow rate of the compressed air. (Flow control)

Compressor Anti-surge Control

  • Selector control (YS's proprietary algorithm)
    The controlled object can be automatically switched over between two different factors, namely, flow rate and pressure.
  • Fast 50 ms control period (programmable mode)
    Enables follow-up of sudden process changes, and ensures smooth switching.
  • User programming
    Control including a start-up sequence can be tailored for various compressors.
