MENU INDUSTRY | OUR SOLUTIONS Our Solutions Rectifier systems We deliver the perfect solution for our customers’ needs: we supply the rectifier and all the equipment which are part of the conversion system. DISCOVER Applications Our rectifier systems are used in the heavy industry, especially in the processes that require high DC current. Production of chemicals for the production through electrolysis of chemicals used to obtain solvents, PVC, disinfectants for the medical industry. For example: chlorine, caustic soda, sodium hypochlorite and their derivatives. Extraction of aluminium for the melting and extracting process of the aluminium coming from its oxide, alumina. The process takes place within Potline, made by the combination of several electrolytic cells. Metal refining to extract, purify and refine metals such as copper, zinc, cobalt, nickel and other non-ferrous metals within electrolytic cells (called electrowinning and electrorefining processes). Heat treatments For the graphitization process into furnaces or in arc furnaces, where the heating is produced by circulation of direct current through the load. FRIEM rectifier systems are designed to operate in the most challenging operating conditions, maintaining high efficiency over the years. The digital control, entirely designed and manufactured by FRIEM, grants the highest level in terms of reliability, safety and overall performances.
