How To Implement And Control Variable Frequency Drives

May 09, 2016 · Variable Frequency Drives (VFDs) have become ubiquitous in industry for good reasons.They: Are more accurate and repeatable than valves or dampers and do not suffer from hysteresis.This allows controls to be more tightly tuned. Are more efficient.Power is proportional to flow multiplied by pressure; slowing a pump or fan and opening a valve or damper means the same flow …

Improving Boiler System Efficiency: Variable Frequency Drives

Improving Boiler System Efficiency: Variable Frequency Drives. For motors that operate above 7-10 hp, a variable frequency drive (VFD) can help achieve significant energy savings. VFDs automatically throttle the motor when they detect lower loads, reducing the amount of time the motor needs to be running at full speed. This attains better control and less energy consummation, translating to increased overall boiler …
