VFD Line Reactor – Importance of Proper Design


With the increasing focus on energy efficiency, Variable Frequency Drives (VFD) usage have increased rapidly in last few years. VFD penetration in the industrial domain has shot up for attaining energy efficiency, process optimization or control over process parameters. VFD’s are becoming an integral part of the industries and commercial establishments too. Whether a VFD is installed on chiller water pump, or boiler feed water pump or on a dosing pump motor in chemical industries, all these applications are critical applications. Any problem in the VFD will cause tripping of these critical equipments affecting productivity, quality and reliability of the system.
This case study presents a situation where one plant installed line reactor without understanding its purpose, and suffered subsequently. Poor selection and wrong design led to substantial financial loss.
