ADVANTAGES:
Ceramic Random Packing, Is widely used in the scrubbing tower, dry tower, absorb tower, colling tower, those are used in chemical, metallurgical, gas, oxygen,medicine, acid, fertilizer and so on.

Advantages: excellent acid resistance and heat resistance. it can resist to corrosion of various inorganic acid, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature condition.  

Pall Ring, the structure improve distribution of gas-liquid  and its efficiency can be improved  above 50%,and only has half of pressure drop compared with Raschig ring. 

Features: Pall ring has some advantages, such as lower pressure drop, big flux, high efficiency, which HYPAK packing has better efficiency and lower pressure drop and better distribution of liquid compared with common pall ring.
