Mitchell, Lewis & Staver is proud to be expert in the specing, installation and use of Variable Frequency Drives (VFDs): one of the great boons of innovative pumping systems today and a major source of savings in energy, water and labor costs. In fact, these long-lasting solutions often save enough money in a matter of months to pay for themselves.
VFD’s are a “smart” technology, providing precise, automated control of premium pump and irrigation systems and delivering the right amount of water, where and when you need it. VFD computer displays also allow for constant monitoring of key indicators throughout your operations saving time spent adjusting hardware and extending maintenance schedules to the point they become “trouble free."
A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives. Variable-frequency drives are widely used. For example, in water booster stations, pump speed is controlled by the VFD based on system demand.
Our tech experts provide full support in the selection, programming and implementation of turnkey VFD solutions, including their use with integrated control panels that will help you significantly improve pump and blower efficiency. In this way, we can offer you the greatest opportunity for energy savings in applications where speed, pressure, and/or level control are critical.
