Mitsubishi FR Series VFDs can vary the speed (or frequency) of pump motors that don’t have to run consistently at top speed allowing wastewater treatment plants to save big on energy costs.

Mitsuibishi Electric FR-F800 inverters solve tough waste water problems by preventing clogging in pumps! De-Ragging/Pump Cleaning feature detects an excess increase in pressure and triggers a self-clearing sequence that will consist of increasing power and/or cycling the pump back and forward to dislodge the blockage.

  • Cleaning/De-ragging function (pump cleaning)
  • Increases pump efficiency, reducing energy costs
  • Up to 50% energy savings in aeration blowers
  • Reduced vibration and “water hammer” effect
  • Better control of blower fans and pumps
