PEI was the general contractor for installing three-300 HP Variable Frequency Drives at an existing wastewater pumping station. PEI provided all of this project’s required hardware including the VFD’s to interface with the existing PLC.
The drives were purchased as open drives, and installed in custom panels designed and provided by PEI, complete with hardwire interlocking for permissives and alarming. PEI had success with providing a separate hardwired back-up panel to assume all controls, as there had been occurrences of liquid levels or PLC failure prior to the installation.
PEI provided all scheduling activities for drive installation and testing while the station remained operational. As general contractor, trade bids for electrical, concrete, miscellaneous piping, and painting were solicited. The qualified professional contractors were hired under PEI’s umbrella.
