Nutter ring packing has been tested by FRI and industrial practice, and it has been proved to have outstanding performance over other bulk packing. It has also been proved to have superior performance in industrial applications with 6m tower diameter. The packing has the characteristics of large flux, low pressure, high mass transfer efficiency and large operation elasticity. Compared with the corresponding size of the Pall ring, the flux can be increased by 10% while the pressure drop is only 40% of that of the Pall ring. Due to the advantages of pressure drop and efficiency, the operating elasticity of the packing can reach 10:1. The stiffness of the structure shape is very good, the height of the packing layer of the metal Knut ring can reach 15m, but also due to the advantages of the shape, the packing is easy to be evenly arranged in the tower during installation.

● Due to horizontal liquid diffusion and continuous renewal of the liquid film, the efficiency is greatly improved.

● In the process of mass and heat transfer, excellent surface utilization, can reduce the height of the material layer.

● Proved to be a high performance bulk packing by the Distillation Institute of America (FRI) test.

● Good mechanical mechanism provides bulk heap performance and nest heap shape.
