dixon ring, dixon packing rings
The dixon ring is aslo named as dixon θ packing ring , dixon ring, dixon θ packing rings are the highly efficient packing of small particles. It’s made of metal mesh with the same diameter and height. θ Dixon ring is used mainly for laboratory and low-volume, high-purity product separation process. Dixon ring packings’ pressure drop is related to gas velocity, liquid spray volume, and material weight, surface tension, viscosity and characteristics of fill factors and pre-fill liquid. ring hysteresis loop filler material than similar entities fill large, θ dixon ring surface wetting situation completely than ordinary ceramic ring, film-forming rate, and thus more efficient. Dixon ring packing with the theoretical plate number of the increase in gas velocity increased, with the filler surface wettability and reduce the rate of decline.

ceramic cascade ring, ceramic cascade mini ring
The ceramic cascade ring, ceramic cascade mini ring is a different kind random tower packing with raschig ring and ceramic pall ring, ceramic cascade ring is developed on the basis of and raschig ring. Ceramic cascade ring, ceramic cascade mini ring’s heights are decreased and ceramic tube wall is thinned. Due to the additional conical rolled edge, the mechanical strength of the ring is improved and the rings symmetry is destroyed. Sion-Chepack’s ceramic cascade ring has an aspect ratio of only 1: 3 or 1:2 etc. Its height is typically only 1/3 or 1/2 of its diameter. This minor change in geometry has made a profound effect on the process performance of the packing. When the ceramic cascade ring dumped in a tower, the flat cascade rings formation tends to make themselves preferentially in a near horizontal position. with their cylindrical axis predominantly in the direction of the vapor and liquid flow. This is exactly the opposite of the tendency of pall ring and other same high aspect ratio ceramic rodom tower packing.
Ceramic cascade rings can be widely used in various packing towers of desiccation, absorption, cooling, washing, and regeneration in industries of petrochemical, chemical, metallurgy, gas and oxygen generation

ceramic pall ring
ceramic-pall-ring
The ceramic pall ring a very popular ceramic random packings, ceramic pall rings are originated by the improvement of ceramic raschig ring. Ceramic pall ring is a open-hole ring packing that the height and diameter is same and with 5 ligules toward inside at every floor. Usually, the open surface is 30% of the whole wall surface, pall rings’ character helps the liquid and gas pass in packing tower pass freely from the windows of the rings. The Pall Ring open structures effectuate separation of gas and liquid streams and facilitate a more effective mass transfer. and decrease the pressure drop. Sion-Cheapck is the top leading manufacturer, supplier, exporter for ceramic pall ring column packing. Our product has also been choosen and used in the project of 500 Global corporations,such as Sinopec & CNOOC etc.
