A random packed bed is held on a Packing Support Plate.
The essential attributes of the support plate are to have a high percentage of open area so as to not inhibit the capacity of the tower.
This allows the unrestricted counter-current flow of both liquid and vapour through it.
A support plate can be supplied in sections to allow easy installation through access manways. It is usually installed on an internal ring or support ledge.
Additional support beams should be considered in larger towers to provide the necessary structural support.
