Hold Down Grids -Bed Limiters TCI hold down grid -Bed limiters are made from a wire mesh (or expanded metal) screen attached to an annular frame. the Free area of TCI hold down grid-Bed limiters for vapour and liquid flow is normally greater than 85% of the column cross sectional area. For random packing beds: Perforated plate or mesh type Separate or integral with liquid distributor Plastic or metal construction For structured packing beds: Bar / angle construction For catalyst beds: Perforated screen type
