Blower Control Panels & PLCs
The automation layer that translates DO readings into real-time blower speed and valve position commands.
PLC-based control loops read DO probe input and adjust blower speed (via VFD) or diffuser valve position to maintain setpoint automatically.
Well-tuned control loops reduce both energy cost and DO variability compared to manual operator adjustment throughout a shift.
Watch for: control loop oscillation (hunting) from poorly tuned PID parameters, and communication faults between the PLC and field-mounted DO probes.
