cascade ring 1 high void ratio 2 low pressure drop 3 low mass-transfer unit height 4 hige flooding point

  cascade ring is  made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP),  

 Features 

It has features such as high free volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency and so on, and the application temperature in media ranges from 60to 150. For these reasons it is widely used in the packing towers in petroleum industry, chemical industry, alkali-Chloride industry, coal gas industry and environmental protection, etc.

It is used in absorbing and washing tower.
