    The patented DuroShell design provides

    a new level of robustness compared to

    conventional plate-and-shell technology:

     2 times thermal fatigue resistance

     5 times pressure fatigue resistance

    Unpresidented robustness - DuroShell – a plate-and-shell made tougher

  • The patented cut-wing plate enables multi-pass configuration and distribution tubes enhance flow distribution as well as gives structural support

     Good thermal performance for long temperature programs

     Multi-pass cross flow gives counter- current flow

     Plate pack support enhance fatigue resistance

    Conventional Plate & Shell Heat Exchanger

     Uneven radial expansion gives stress concentrations

     No plate pack support

     Peak stresses leads to poor fatigue resistance

    Unique plate design gives robustness - Alfa Laval DuroShell vs conventional plate-and-shell

    DuroShell Heat Exchanger

     Even radial expansion results in no peak stress areas

     Plate pack reinforced by distribution tube

     No weak spots leads to good fatigue resistance

    Conventional Plate & Shell Heat Exchanger

     Low flow zones - poor heat transfer and

    fouling

     Shell side can by-pass - poor heat transfer

    Unique plate design gives distribution - Alfa Laval DuroShell vs conventional plate-and-shell

    DuroShell

     Distribution tube provide even flow

    distribution - good heat transfer

     Large plate opening on shell side gives even

    flow distribution - good heat transfer

    Alfa Laval DuroShell - Plate-and-shell made tougher

     Robustness due to fully welded design

    and unique plate design

     High resistance to thermal and

    mechanical fatigue

     Superior thermal performance

     Compact solution

     Global service

    Thermal performance Reliability Compactness Serviceability
