Plastic bilayer rosette ring is a new type of plastic packing with two layers of circular garland and a stiffener in the middle. The special structure greatly improves the compressive strength of the packing bed.
As the large liquid holding capacity, the residence time of the liquid in the column is long, which increases the contact time of the gas-liquid phases and improves the mass transfer efficiency of the packing.
As a leading manufacturer of plastic bilayer rosette rings, we have the expertise in the operational requirements and compliance and standards of many different industries across the globe, we can help you choose the best product for your requirements.
Materials: PE, PP, RPP, PVC, CPVC, PVDF, etc.
High capacity and low pressure drop
Strong resistance to chemical corrosion
Energy saving and easy to operate
High separation efficiency
As with high mass transfer rate, good gas-liquid separation efficiency and low operating cost, plastic bilayer rosette rings can be used in washing cooling towers, harm removal tower, dichlorination tower, deaerator, reactor and other gas-liquid contact systems.
