Cascade ring, a packing media designed to give enhanced capacity, increased efficiency and mechanical strength over the older style Pall ring packing. The height/diameter ratio of the packing is 0.5 which is only half that of the known Pall Ring. Because of this aspect ratio, when this packing is installed in a tower it tends to orient in a more structured way such that its inner surface could be more efficient. All these features, therefore, decrease its pressure drop and increase the mass transfer efficiency.
