Chess IPR

Our History

Chess IPR began servicing the GE Industrial Power Rectifier (IPR) business as a Sales Representative company, contracted by Siemens/ASI Robicon, back in 2002. A few years after this relationship began ASIRobicon made a decision to discontinue supporting this product line. Chess IPR quickly stepped in and purchased the business in 2006. We knew there was work required to reestablish lost communication links and injured customer relations. Our intentions were to immediately improve on past service and rebuild those damaged relationships.

Chess IPR is dedicated to the IPR business and will continue to support our customer’s needs as well as offer power and control (digital) upgrades. We own all intellectual property concerning the GE Canada manufactured Industrial Power Rectifier which positions us to best serve our customer’s IPR needs.

Chess IPR is located in Peterborough, ON, the original home of GE Canada’s IPR manufacturing.
