VFD Optimization
NRCS National Conservation Innovation Grant (CIG) “VFD Optimization” Existing Systems w/ VFDs Expect additional 10% to 30% Energy Savings 3 yr. Project (Started October 1 st 2012) Project Completed September 2015
VFD Optimization What is a VFD VFD = Variable Frequency Drive Throttle to control the electric motor speed Variation of Flow and/or Pressure Best Results on Turbine and Submersible Pumps Electrical Savings bases on Pump Curve Improves System Operation

So….How do VFD’s Save Water?? Only Run the sprinklers needed Pressure at the Sprinkler. Any sprinkler without a pressure regulator or flow control nozzle will apply more water when pressure increases. Mainline and System Failure. Overpressure Water Hammer
