Variable Frequency Drives

Capital Investment Opportunity

Variable frequency drives (VFDs) adjust motor speed and torque by modulating the voltage and frequency. They are often used in HVAC fans and hydronic pump motors. VFDs can match the speed of the motor to the required load, therefore, saving energy during low demands.

Variable Frequency Drives

CONSIDERATIONS

  • Ensure motor is VFD rated.
  • Check with your utility as their could be sizeable rebates.
  • Recommended for motors with variable loads.
  • Prolong life of the motor and equipment.

KEY PERFORMANCE INDICATORS (KPIS)

  • 1-3 point energy use intensity (EUI) reduction potential
  • 1- 5% sitewide electric savings
  • 3 year simple payback
