Plastic teller rosette is by designed Teller.A.J., an American, in 1954. It is a type of random packing in oblate shape, arranged by 12 annuluses according to their radial directions. The appearance of plastic teller rosette is similar to a spherosome which is composed by end-to-end spiral spring. Its core characteristics are large porosity, great flux, small resistance and so forth. Because of its high liquid holdup, the contact time and the contact area of the gas and the liquid in the towers are prolonged. Plastic teller rosettes in different sizes can be customized to meet customers' demands. Meanwhile, users can choose plastic teller rosettes with different materials (PP, RPP PVC, CPVC, PVDF, etc.) according to the use condition (pressure, temperature, medium, etc.) of packing towers.
