Two Metso Fiberboard Optimizer modules was installed at Medite MDF, Clonmel, Ireland, to optimize and control the two EVO Defibrator systems.
Each of the modules controlled pre-steaming flow, retention time, pre-heater pressure and disc gap. Each of the systems targeted a certain mat height and minimum energy cost, based on defibrator electrical consumption, steam consumption and dryer energy consumption.
