Why consider using
Provide additional savings by reducing the speed of the motor and therefore the horsepower required to operate.
Pumps and Fans spend approximately 80% of there time running at 60% speed.
The payback period for installing variable frequency drives is usually less than three years and can be less than a year.
Enhance the Productivity and Longevity of Equipment
Energy consumption in centrifugal fan and pump applications follows the affinity laws, which means if an application only needs 80 percent flow, the fan or pump will run at 80 percent of rated speed and only requires 50 percent of rated power.
In other words, reducing speed by 20 percent requires only 50 percent of the power.
Variable Frequency Technology
What is a Variable Frequency Drive (VFD)?
A type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage.
Longer motor life
