Maximizing Space Minimizes Cost

Craig Hartman (Director of Energy) and Doug Stewart (Electrical Engineer) knew that retrofitting the plasma-cupola process with variable frequency drive (VFD) systems would improve Geneva Steel’s steelmaking capabilities. But they also knew there simply wasn’t enough room.

Sixteen, 25 through 60 horsepower VFD build ups and an I/O cabinet were needed, which was 235% more equipment than the eighteen feet of available space could accommodate.

“If we had only used the number of VFD build ups the room allowed, then we wouldn’t have been able to save energy or improve precision,” said Stewart.

“And the cost of constructing a second building was enormous,” added Craig Hartman.

Then, Hartman and Stewart sat down with a team of engineers from Energy Management Corp., the local supplier of MDI Systems VFD packages.

“When they (Geneva Steel) explained the situation to us, we knew it was a perfect application for the MDI Systems VFD Power Center, with the ‘Slide-a-Drive’ option,” stated Steve Rossiter, President of Energy Management Corp.

MDI Systems Slide-a- Drive(TM) technology allowed Geneva Steel to fit sixteen VFD systems, each with 5% line reactors, and a two-foot I/O cabinet within an 18-foot span along the north (right) wall of this control center.
