When corrosion is an issue use the DIABON® range of plate heat exchangers. Indestructable even for the toughest media.     Alfa Laval and SGL Carbon, Germany, worked together to develop DIABON® plate heat exchangers. This collaborative effort combines Alfa Laval’s plate heat exchanger know-how with SGL Carbon’s expertise in graphite process equipment. The resulting product combines the high-efficiency heat transfer benefits of conventional plate heat exchangers with the exceptional corrosion resistance of graphite material. DIABON® plate heat exchangers are therefore ideal for handling highly corrosive fluids such as: - hydrochloric acid and gas in all concentrations - sulphuric acid up to 90% - hydrofluoric acid up to 60% - all concentrations of phosphoric acid - pickling acids in surface treatment plants - electrolytes used in the mining industry mixed acids - chlorinated hydrocarbons - catalysts such as aluminium chloride.
