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.
