Plastic Tellerette rosette ring, also named as plastic Teller rosette ring, was designed by Tell A J in 1956, which has several small rings arranged in order within a large ring.
As the gap filler can be at a higher liquid holdup, the tower can remain liquid longer, thus increase the gas-liquid contact time, improve the efficiency of mass transfer packing. Plastic Tellerette rosette ring has features such as high free volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency, etc.
Plastic Tellerette rosette ring is available in different materials, shapes and sizes.
Materials: PE, PP, RPP, PVC, CPVC, PVDF, etc.
High active surface areas and extremely low pressure drops
Extremely high operating capacities
Symmetrical geometry made from a unique network of ribs, struts, and drip rods
High mass and heat transfer rates and excellent gas and liquid dispersion characteristics
As with the characteristics of low pressure drop, great energy and high efficiency of mass transfer, plastic Tellerette rosette ring has been used as packing of high corrosion resistance and low pressure drop with extensive application for gas absorber, cooling tower, deaerator, reactor and other gas-liquid contact systems.
