Metal Cascade Mini Ring

Metal Cascade Mini Ring, draws the benefits of Metal Raschig Ring and Metal Pall ring, the height-diameter ratio is 1:2.

Because of increasing the cone flanging, it can reduce the resistance of gas and increase gas-liquid contact area.

Metal Cascade Mini Ring, has features such as thin wall, heat resistant, high free volume, high capacity, low resistance, high separation efficiency, reduced pressure drop and so on.

Reduced Pressure drop, because its largest opening predominantly in the direction of the gas-liquid flow which allows for easy passage.

Increased plant capacity, is the direct result of the result of the reduction in pressure drop.

Higher operational efficiency, because of the preferential orientation which ensures that in most of the ring surface are positioned vertically rather than horizontally, and this is also advantageous for mass transfer. Improved resistance to fouling, because any solids entering the packed bed are more easily flushed through the packing matrix.

Material:carbon steel; SS 304, SS 304L, SS 410, SS 316, SS 316L.


  • Suitable for the materials which are easy to decompose, aggregate or carbonize.
  • Used in fractionators and quench towers.
  • Used in various extraction and fractionation applications.
  • Applied in methanol separation and organic acids separation.
  • Applied in carbon dioxide degassing tower, ozone contact reaction tower, mist purification tower and synthesis reaction column.
