Type

Conventional

ASU Packing

Its plain edge design has improved the gas-liquid flow at the interface of two adjacent packing tray to decrease local resistance, avoid early flooding and enlarge the

equipment flexibility range.

High

Throughout

Packing

Especially applicable in large scale ASU. Its special edge curve transition structure

has good division effect to reduce the liquid accumulation among packing trays,

increase the packing flooding point and the operation flexibility.

Copper MadeASU

Packing

Especially applicable in the oxygen-rich section of ASU and in precious gas packing.

Compared to aluminium alloy material, it shows higher mass transfer capability and

safety performance.
