DIABON® plate heat exchangers

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.
