FIELD: packing tower is used in aggregates, in which mediums are in direct contact for energy and / or substances exchange, or for chemical or biological reactions, or for mixing or separating processes, for example, for spraying lattices or for drops separators in scrubbers, for direct heat-exchangers, for drop type biofilters in aggregates for biological purification of sewage, for chemical columns, for distributors of liquids and / or gasses and their mixers, for apparatuses of air feeding. SUBSTANCE: packing tower is made of several foil plates of wavy form with given amplitude and wavelength, that are connected with each other with alignment of ridge and deepening of wave to form running-through canals. Running-through canals have at least two turns along their path. Neighboring sections of correspondingly two successive in one layer plates are joined each other just by zones and over other their part of length there is open slot, that links neighboring running-through canals. Cross-sections of slots are equal just to part of cross-section of linked by them running-through canals. EFFECT: improved process. 10 cl, 25 dwg
