Plastic Ralu rings are injection-molded from materials with good high-temperature resistance and corrosion resistance. The main materials include PP, PE, RPP, PVC, CPVC and PVDF.
It features a high void ratio, which helps to increase the gas-liquid contact area and thereby enhance the mass transfer efficiency.
A low specific gravity means that the packing material is light in weight, which is convenient for loading, unloading and transportation

The plastic Ralu ring is an improved high-efficiency random packing based on the Pall ring. Its core design optimization includes adding conical flanges and internal distribution points, while maintaining the structural feature of a height-to-diameter ratio of 1. This improvement makes the liquid distribution within the packing layer more uniform and accelerates the surface renewal rate.
Low pressure drop:
Plastic Ralu rings have the characteristic of low pressure drop, which means that when gas and liquid pass through the packing layer, the pressure loss is relatively small, which helps to reduce energy consumption
High flux:
High flux means that a large amount of gas and liquid pass through the packing layer per unit time, which can improve production efficiency
High mass transfer efficiency:
It has a relatively high mass transfer efficiency, which means that in processes such as separation, absorption, and desorption, the transfer and separation of substances can be achieved more effectively
Good liquid distribution:
The liquid is evenly distributed within the packing layer, which helps to enhance the uniformity and efficiency of the reaction
Low cost:
Compared with fillers made of other materials, plastic Laroo rings have a lower cost and offer a high cost-performance ratio
