For applications in certain columns, it is necessary to load several packed bed stages with different liquids. Between such column stages there is both a support grid for the packing and a collecting tray for the down flowing liquid. RVT's Combi element combines these functions into one part. Additional advantages are low pressure drop and very low weeping rates. It is recommended to put the Combi element onto a ring channel inside the column. Depending on column diameter, additional support beams may be necessary.

These lids are pushed upwards at sufficient steam load in the column by the pressure of the steam and the steam can flow through the holes and the liquid. The pressure of the steam then prevents the liquid from flowing through the holes. If the steam load decreases, then the hinged lids close and thus prevent a drainage of the liquid.
