Benefits of using Variable Frequency Drives VFDs

Reduce energy consumption and Operating Costs

Variable Frequency Drives allow for the precise matching of the speed of motor-driven equipment to the load requirement, thereby reducing energy consumption by as much as 50%. There is no other method of AC electric motor control that allows you to accomplish this.

Extend Equipment Life and Reduce Maintenance

Optimal motor application speed and elimination of short cycling, ensures equipment will last longer and have less downtime due to maintenance. Optimal control of frequency and voltage also offers better motor protection from issues such as electro thermal overloads, phase protection, under voltage, and overvoltage.

Soft Starting and Reduction Inrush Current

Loads started with VFDs can have smooth acceleration and deceleration cycles, rather than subjecting motors to the “instant shock” of across the line starting. Reduction of mechanical stress eliminates belt, gear, and bearing wear. Substantial reduction of amps required during motor startup lowers peak demand charges.

Increase Production through Tighter Process Control

For manufacturing applications, operating motors at the most efficient speed for the application means fewer mistakes and increased production levels. For example, on conveyors and belts, jerks on start-up are eliminated, allowing high through-put and reduced production costs.

Improve Temperature for HVAC Applications

Tighter control of return temperatures with VFDs means AHUs and chillers can modulate the flow of conditioned air and water throughout a building with a much higher resolution, creating a more consistent temperature and humidity level.

Reduce Audible Noise

Slower speeds translate to less noise output and vibration from fans and pumps, lowering occupant disturbance and improving occupant comfort.
