Use of VFDs on Asphalt Plant Induced Draft Fans

Use of VFDs on Asphalt Plant Induced Draft Fans. Studies of 10 asphalt plants in the Intermountain Region have identified average ID fan energy savings of 68% by controlling airflow using Variable Frequency Drives (VFDs) on the fan motors in place of damper control (inlet or outlet). Average paybacks were 3-5 years before utility incentives.
