Calendering hole Packing, also known as Cannon Packing, was developed in the UK in 1949. It is made of many thin stainless steel metal sheets with small holes, but the punching does not remove the metal, but makes it protruding and become a rough surface, which is beneficial to the wetting of liquid on the surface of the Packing. It is not like filler wire mesh type coil must be repeatedly before distillation flooding make its wetting, is a kind of efficient packing used in laboratory, mechanical strength is larger, the theoretical plate number is higher, especially suitable for the test in the laboratory column experiment, and mixed loading of large industrial tower packing, so it is of high mass transfer performance, belonging to one of the efficient tower packing.

The calendering ring filler produced by our company is mainly used in the separation process of laboratory and small batch and high purity products. Its strength is greater than other experimental fillers.
