Plastic cross spherical ring is a kind of new developed plastic random packing with a cross partition plate inside of two vertically arranged rings. With this special structure, plastic cross spherical ring is comparable to the performance of structured fillers.
Compared with traditional plastic random packings, the specific surface area of plastic cross spherical ring is much higher, and it has lower resistance, higher mass transfer efficiency.
We offer a wide range of plastic cross spherical rings which are made of heat resistant and chemical corrosion resistant plastics.
Materials: PE, PP, RPP, PVC, CPVC, PVDF, etc.
High void ratio and low pressure drop
High mass transfer efficiency and small specific weight
Strong resistance to chemical corrosion
High separation efficiency
The large void fraction and surface area, the low pressure drop, high mass transfer efficiency make it be widely used in the packing towers in petroleum industry, chemical industry, alkali chloride industry, coal gas industry and environmental protection, etc.
