PFC FSi300 Rebuild
Following a maintenance request from a large aggregate manufacturing plant just outside London we carried out a service on what turned out to be one of our Power Factor Correction units, a FSi300 originally built by us in 2007 for a 3rd party installer.
The unit had never been serviced since installation and due to its dusty environment years of accumulated dirt had built up in and around the unit which eventually led to the site isolating the unit in 2020 where it had been left ever since.
During our service, we found multiple capacitor failures along with lots of rust on the detuning reactors. All the ventilation fans in the roof had also seized and the unit’s key had ben lost.
Due to the failures and lack of servicing the best option was to replace the internal trays with new ones, including all capacitors, contactors and fuses. Along with this we also replace all the fans in the roof and upgraded the control relay to the latest Lovato DCRL range.
Upon completion, the site had improved its Power Factor from .041 inductive to 0.99 with all works being carried out during normal working hours without any disruption to site operation.
