Flow Control

The easiest and most effective way to control compressed air system pressure and flow with an online monitoring application.

The CAEMS Flow Controller (CFC) & Compressed Air Control System controls Compressors and the airflow/pressure being delivered thereby reducing artificial demand in the Plant.

CFC is a flow control valve used with CAEMS CS-x box for regulation and online optimization purpose. By performing a CALMS CFC analysis on a compressed air system, the lowest possible operating air pressure will be learned. Using this calculation, big enough storage and CFCs unique ability to meter compressed air at constant pressure, overall demand-side pressure can be lowered. By lowering demand-side pressure, leaks will consume less compressed air, thus saving considerable energy.

Benefits of CAEMS Flow Controller CFC

  • Simplified electrical regulation valve with special designed butterfly valve disc.
  • Isolates Supply side (Compressors) from Dmand side (peaks)
  • Saves Compressed Air Energy through a reduction in Artificial Demand.
  • Calculated flow – CFC is calibrated in our Flowstand to meassure flow 0-120 m/s
  • Online monitoring – CFC is the only device that has online monitoring and analysis connection available
  • Reduces leakages losses in the plant.
  • Enhances useful storage capability.
  • Reduces load period of compressors.
  • Ensures LOW and constant (stable) air pressure at the end-use point.
  • Easy Setting the Optimum Plant Pressure on CAEMS with online trending.
