.png)
HY-PAK is an improved design of Pall ring, it has better advantaged than Pall rings, such as:
1) with a larger flux and low pressure drop.
2) to further improve the ring of gas and liquid distribution in favor of mass transfer process.
3) with a wide range of operating flexibility.
4) high mechanical strength.
