Variable Frequency Drives

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.


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
  • Water Source Heat Pump Circulating Loop 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
