The Cascade Mini - Ring was invented by the British company MTL. This packing increases the number of upper bends in the lower position. Это также увеличивает прочность насадки. Cascade mini-ring (CMC) is a new type of irregular packing with rectangular holes, improved on the basis of the shape of Pall rings. The height is reduced by half and several bends are added from the edge of the ring wall. This new structure increases the mechanical strength. Due to the asymmetry of the packing, the chaotic movement in the reaction column increased. The bends of the packing turned the linear contact into a point contact, which not only increases the free space between the rings, but also reduces the gas resistance. Contact points help to disperse the incoming liquid and to improve the exchange of liquids. Therefore, the characteristics of cascading mini-rings are significantly better than those of Pall rings.
