Woodward Peak200 Steam Turbine Control

Woodward Peak200 Steam Turbine Control

  The Peak200 control functions as a turbine control, system sequencer, operator control panel, and first-out indicator. This encompassing design minimizes external system devices as well as system installation, wiring, and troubleshooting.
  Designed to operate small single valve, or single valve-rack industrial steam turbines, this cost-effective steam turbine controller includes specifically designed algorithms and logic to start, stop, control, and protect small industrial steam turbines or turbo-expanders driving compressors, pumps, or industrial fans. 
  The Peak200 control’s unique PID structure makes it ideal for applications where it is required to control steam plant parameters like turbine speed, turbine load, turbine inlet header pressure, turbine exhaust header pressure, pump flow, or compressor discharge or suction pressure. 

Peak200 control capabilities include:
Turbine speed/load control
Inlet header pressure control
Turbine inlet/exhaust header pressure control
Pump flow/pressure control
Compressor flow/pressure control
