The Pinned Truss is assembled using threaded hardware, allowing the individual components (chords and struts) to be introduced through a vessel manway and installed within the mass transfer tower without welding.

  • Components are designed to pass through the vessel manway
  • No welding inside the column
    • Up to 80% reduction of installation time compared to field-welded solution
  • Simple installation sequence reduces inspection requirements during installation 
  • Interchangeable components
    • Improved maintenance/easy installation
  • Minimized individual component weight 
    • Easier and safer handling
  • High open area can be achieved
  • Reduced shipping volume
