Matrix provides electrical engineering services in the design of systems to control and monitor Ingersoll-Rand CENTAC compressors. These systems consist of a variety of PLC manufacturers and graphical operator interfaces to provide a retrofit to their now obsolete Westinghouse MP3 controller as well as an alternative to the current proprietary controller used by Ingersoll-Rand. We have also integrated these PLC's with many of the customers DCS systems for remote monitoring and control of the compressor. We have implemented these custom control systems on a variety of sizes of IR CENTAC as well as turbine driven units. Client list for this service includes AMOCO, Weyerhaeuser, GE Plastics, Volkswagen, Fluor Daniel and many others for installations both domestic and abroad.
