Variable Frequency Drives (VFD)

By controlling motor speed and torque (twisting force) to accommodate system load variations, VFDs coupled with NEMA premium-efficiency motors offer greatly enhanced system control and efficiency.

Program Details

Standard VFDs incentives are available for the following applications:
  • Building Exhaust Fans
  • Make-Up Air Fans
  • HVAC Return Air Fans
  • Heating Water Pumps
  • Cooling Tower Fans
  • HVAC Supply Air Fans
  • Chilled/Condenser Water Pumps

Alternative VFD incentives may be available for VFD applications on motors larger than 200 hp and elsewhere when system efficiencies are improved by coupling VFDs with non-HVAC motor-driven systems, including:
  • Air Compressor
  • Process Pumps
  • Process Fans
  • Process Machinery
  • Other Processes
