Products introduction:
Ceramic Pall Ring is improved from the ceramic Raschig Ring,Ceramic Pall Ring has add a design of open the holes for the weeks wall ,this construction can improve the surface area and voidage, Ceramic Pall Ring makes porosity distributed even and improves the distribution of the fluid, greater capacity and lower pressure drop than ceramic rasching ring.characters of high mechanical strength, high chemical stability,
Ceramic Pall Ring with excellent acid resistance and heat resistance. They can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature conditions. Consequently their application ranges are very wide. It is widely applied in various packing towers of desiccation, absorption, cooling, washing and regeneration in industries of petrochemical, chemical, metallurgy, gas and oxygen generation.
