Ported Downcomer Beams

The Ported Downcomer beam design was developed to increase the mechanical robustness of the tray  while allowing greater access to the full tray. The Ported Downcomer beam design utilizes the downcomer panels to provide mechanical strength, typically eliminating the need for separate beams and beam seats.

  • Stiffer mechanical section
    • Reduced deflection
    • Improved process performance
  • Active panels are parallel to flow
    • Integral stiffeners have most preferred orientation
    • No resistance to flow
    • Improved process performance
  • Eliminates need for additional welded beam seats
  • Fewer structural components
    • Reduced installation time
  • Elimination of obstructions within tray space
    • Improved installation and maintenance access
    • Improved process performance
