Paul Bartunek, president of Mechanical Sales KC, Inc., has extensive knowledge of VFD applications through his previous work as vice president, HVAC sales, marketing and applications for ABB’s Low Voltage Drives division. Using proprietary conductive filaments, the CDR provides a low impedance path to ground, safely drawing these harmful shaft currents away from the bearings and preventing premature bearing failure. Inpro/Seal’s CDR increases reliability on motors and coupled equipment by protecting the bearings from harmful variable frequency drive (VFD)-induced shaft currents. Their extensive application knowledge and customer focus aligns perfectly with our core principles of innovative application solutions, unmatched customer support and superior speed to market.” Dwight Vicars, Inpro/Seal’s CDR product manager, stated that “Mechanical Sales is a perfect fit for Inpro/Seal in the HVAC market.

The CDR provides a low impedance path to ground– safely diverting these harmful currents away from the bearings and preventing premature bearing failure. Inpro/Seal’s CDR uses proprietary conductive filaments to protect bearings installed in motors and coupled equipment from stray shaft currents generated by variable frequency drives (VFD’s). Today’s order affirms Inpro/Seal’s longstanding position that its CDR does not violate ITW’s patent. ITW subsequently acknowledged that Inpro/Seal’s CDR does not infringe its patent as interpreted by the court, and Judge Zagel today entered an order granting judgment of non-infringement in favor of Inpro/Seal.
