Abstract
A packing element, for use in mass and/or heat transfer columns or towers through which a gas and/or liquid flows, includes at least one first group of strips having a plurality of exchange surfaces formed by the surfaces of half-wave-shaped and/or wave-shaped strips. The periodic length l1 of a strip of the first group of strips adjoins a second group of strips with a periodic length l2, which are matched to each other in such a way, that the two adjoining strips are in contact with each other at at least one point, enabling a liquid transfer between these two strips. The at least one strip extends from a first end bridge to a second end bridge, wherein the two end bridges run along the transverse direction of the packing element. At least one strip of the packing element is torsioned about a longitudinal torsion line of the packing element.
