The existing motors ranged from 350hp to 1000hp at 2300 vac. During the design phase of the project, the Quad Plus team worked with the supplier of the synchronous equipment (Kinetics from Trenton, NJ) to engineer a package that could support a range of field currents. That way, one system could handle the whole range for all seven motors, which would require only a small amount of tuning at startup.
Every team involved in this $45 million project had to work together on a tightly coordinated schedule to complete one pump every six weeks to stay on schedule. The teamwork demonstrated by everyone on this project was exceptional, and we completed all work on time. The City new enjoys a state-ofthe-art system that experiences no delays in service, and is still running smoothly after two years in operation.
Because of the City’s confidence in our service and abilities, Quad Plus is now designing and quoting the replacement of three small VFDs for use on the process water pumps on the City of Chicago’s South Water Purification Plant.
