Continuous Vertical Support Column
The Continuous Vertical Support Column provides a simpler tray installation sequence and reduces total installation time. It provides a rigid structure, which minimizes hot work within the tower without any reduction in the tray bubbling area.
This column is suitable for packed tower revamps involving trays when:
- Changing number of flow passes
- Increasing or decreasing tray spacing
- Changing tray orientation
- Converting packed tower to trays
Expansion rings are used to provide support for the trays where there is no existing welded support ring. The expansion rings can be leveled even when existing tray support rings are significantly out of level. The continuous vertical columns provide a more leak-resistant connection to the downcomer.
