The Mission Rubber Company (MRC) clinic team designed an energy diagnostic and monitoring (EDM) system that measures, records, and graphically displays power used by industrial rubber presses. A prototype version of the EDM system was installed at the MRC manufacturing facility in Corona, whose annual energy use (10 GWh) could power nearly 1,000 homes. The EDM will be used to compare the operating power of different ma-chines, recognize power inefficiencies and quantify the effects of energy reduction programs.
