Graphite Heat Exchangers

DIABON® graphite shell and tube heat exchanger

Extreme corrosion resistance: full material impregnation with first class phenolic resins and a wide range of graphite qualities (fine and ultra-fine graphite etc.)

  •   Robustness: robust design and monolithic tubesheets up to 1600 mm in diameter to enable high plant availability. Significant reduced risk of damages/unplanned production stops.
  •  Safety: up to 10 – 20 times less tube breakages at critical operation conditions when using SGL Group’s carbon fiber reinforcement technology.
  •  Compactness: ultra efficient graphite tube qualities with heat conductivities up to II 130/ –I 70 W/mK (certified by TÜV). Reduced fouling by lower wall temperatures.
  •  Flexibility: large range of design and material options (e. g. falling film, multi-pass, gas/liquid separation etc.)
  • Maintenance friendly: easy to clean and quick repair procedures for minimized shut down times.Service excellence: fast and competent services along with the complete lifecycle offered by our global service network.Example applications
    •   Corrosive media: e. g. hydrochloric acid, sulphuric acid, phosphoric acid, hydrofluoric acid, halogenated hydro- carbons etc.
    •   Functions: heating, cooling, condensation, evaporation, absorption, heat recovery by interchanger
