Hold Down Grid / Bed Limiter for random packing is used because vapor load has potential for moving the packing media. When top packing layers top have potential of upward displacement in the structured packing, Hold Down Grid is recommended. Where the upward displacement of structured packing is not a concern, the distributor over the packed bed can also be used as bed limiter.
