plastic raschig ring, polyhedral (pp) raschig rings
Plastic raschig ring have large void rate, and has low height of mass transfer unit, high extensive point, full contact of gas and liquid, low specific weight and high mass transfer efficiency. It is widely used in the packing towers, petroleum industry, chemical industry, alkali-Chloride industry, coal gas industry and environmental protection and etc.

why ceramic saddle rings can be widely used in RTO, RCO, CTO
The reason for the ceramic saddle rings saddles frequently utilized as a protection layer to the upper ceramic media blocks. As the ceramic saddles are made from chemical porcelain, after fired, the product could have excellent resistance to acids except HF acid. And its moisture absorption is lower than 1%. And ceramic saddles also have an average heat capacity (between 20℃, 68F and 500℃, 932F of 0.22 cal/g.℃). The softening point is 1400℃, 2552F. So ceramic intalox saddles product’s good high/low temperature resistance and excellent acid-alkali resistant performance can make it act as mass media in the RTO, RCO ( regenerative catalytic oxidizer ), and CTO ( catalytic thermal oxidizers ). Except that ceraimic saddles could also used to protect against damage that may occur from large amounts of particulates and excessive burner volume applied directly to the ceramic block media, it helps to further protect the block media from damage caused by direct burner flames. and its size option base on the on the system size and the process stream

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.
