4. VFD Optimization

5. 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

6. 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

9. VFD Optimization Improve Control Methods Pre-Set Pressure Setting Switch Potentiometer Wireless Pressure Control from remote location Make the VFD EASY to Adjust Pressure

10. VFD Optimization

12. 3-Setting Switch 50-55-62

13. Toggle Switch High/Low 50psi or 40 psi

14. VFD Wireless Radio Control

16. VFD Optimization Wireless Pressure Control
