Ramp up operating flexibility with variable-frequency drives
Benefits offered by variable-frequency drives (VFDs)--more precise process control, energy saving, and less start/stop wear on equipment--have been widely publicized. In response, application of the drives has been steadily climbing since their introduction to the industry during the energy crises of the 1970s. Recently, digital electronics have enhanced the technology, and as the importance of operating flexibility grows, application of VFDs has now become mainstream for both new-construction and retrofit projects. The drives can be applied virtually anywhere there are pumps, fans, blowers, material-handling equipment, chillers, conveyors--in other words, throughout the entire powerplant. These devices shine when systems must operate at varying loads or under cycling conditions; hence they are one means of meeting today`s mandate for operating flexibility. This article describes how properly applying the technology and avoiding some common pitfalls will help stretch retrofit or new-construction funds.
