Good vapor-liquid distribution,high mechanical strength. 36 years professional experience for ceramic random tower packing
With the characters of high mechanical strength, high chemical stability, and excellent heat endurance.Ceramic Pall Ring can resist high temperature, acid ( except HF ), alkali, salt and various organic solvents. 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.
Generally, the area for open windows occupies 30% of the total area of the tube wall. It helps vapor and liquid flow freely through these windows, making full use of the ring’s inner surface to improve distribution of vapor-liquid.
