VFDs in Today’s Commercial and Agricultural Water Systems
Each year, more and more variable frequency drives (VFDs) are being used in commercial and agricultural water systems. And, as this year’s NGWA trade show will demonstrate, more and more VFD manufacturers are offering and targeting the water systems industry with their products. This session will provide an overview of VFDs in today’s water systems industry, including the commercial and technical advantages of using a VFD. From there, the session will cover some installation guidelines common to all manufacturers such as sizing, general programming, sensors, and filtering. Included will be ways to avoid some common misapplications of VFDs to water systems. The session will conclude with three specific “real life” case histories and the gains that were achieved when a VFD was added to a conventional high horsepower water system.
