Plastic Cascade Mini Ring, draws the benefits of Plastic Raschig Ring and Plastic Pall Ring, the height-diameter ratio is 1:2. Because of increasing the cone flanging, it can reduce the resistance of gas and increase the gas-liquid contact area.

Plastic Cascade Mini Ring, has features such as high void ratio, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high efficiency of mass transfer. 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
