VARIABLE FREQUENCY DRIVES
 

Variable Frequency Drives (VFDs) can be used to save large amounts of electricity when motor loads vary significantly. Examples of applications for VFDs include pumps, fans and other fluid handling equipment. VFDs can also be used on chillers and compressors to improve system efficiency. The following table provides incentives based on the rated horsepower of the VFD:
