Ceramic Pall Ring is a hole ring packing, developed on the basis of Ceramic Raschig rings with equal height and diameter. For each layer, there are four ligules being inward the axes of the ring. The open position for windows between the two layer is stagered oppositely. Generally the area of wall openings is about 30% of the total area, making gases and liquids in the packed towers flow freely through the windows, improving gas-liquid distribution, and making full use of the inner surface of the ring.

 

 

Ceramic Pall Ring has excellent acid& heat resistance performance, and can resist corrosion of diverse acids such as inorganic acids, organic acids and organic solvents except hydrofluoric acid

 

 

It is suitable in all occasions of high-temperature, and can be widely used in drying tower, absorption tower, cooling tower, scrubber and regeneration tower among the fields of chemical industry, metallurgy, gas, and environmental protection industries.
