Plastic hiflow ring is the third generation of high-performance tower packing. Compared with plastic pall ring, plastic hiflow ring has higher void fraction, higher fluid flux, lower pressure drop. The vertical bar staggered distribution and reinforced horizontal stripe largely improve its rigidity and strength. In addition, it has features such as low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency and so on.
Plastic hiflow ring is widely used in absorbers, liquid/liquid extraction, degassing, heat transfer, water treatment, etc.
Materials: PE, PP, RPP, PVC, CPVC, PVDF, etc.
Big flux, low pressure drop, good anti-impaction capability
Strong resistance to chemical corrosion
Large void space
Energy saving, low operation cost and easy to be load and unload
As a high-performance tower packing, the strong lattice shape of plastic hiflow ring provides high mechanical stability along with a very high void fraction. And it can be widely used in petroleum and chemical, alkali chloride, gas and environmental protection industries.
