We turn off the lights when we leave the room. We turn down the A/C when we go on vacation. We turn off the water faucet when we’re not using it. So why are many companies running their pumps at full speed when it’s not needed?
Variable Frequency Drives
Variable frequency drives (VFD) reduce the total energy cost and life cycle cost (LCC) of an industrial pump, fan or compressor. The load profile for any industrial motor varies depending on multiple factors such as weather conditions and facility usage. VFDs are often a good choice for motors that don’t need to constantly run at 100%. They are able to monitor demand and change the motor output to match the load profile, ultimately making the motor more efficient and increasing energy savings. Also, VFDs help reduce the life cycle cost of a motor when it isn’t running at full speed at all times.
