Product Description

The PTFE cascade ring with height-diameter ratio of 1:2 is improved on the basis of short Raschig ring and Pall ring, and is designed with a tapered flange at one end to reduce the resistance of gas flowing through the bed, Increase throughput and filler strength.
Make the gas-liquid distribution uniform, increase the gas-liquid contact area, and improve the mass transfer efficiency.
