High Mass Transfer Media Teller Rosette Ring Packing for Chemical Industry
Introduced by the United States in 1954, commonly known as "Teller Rosette" domestically, this packing consists of 12 small rings arranged radially to form a large flat sphere, similar to a spiral spring coiled into a spherical shape. It has become a serialized product with three models available. Key features include high void fraction, resistance to clogging, large throughput, and low resistance. The high liquid holdup in the gaps allows for longer liquid residence time in the tower, enhancing gas-liquid contact and separation efficiency. Users can select materials such as Polypropylene (PP), RPP (Glass-reinforced Polypropylene), Polyvinyl Chloride (PVC), Chlorinated Polyvinyl Chloride (CPVC), Polyvinylidene Fluoride (PVDF), etc., based on tower operating conditions (temperature, pressure, media, etc.).

Low pressure, high energy, high mass transfer efficiency, users can choose different materials such as polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polychlorozene (CPVC), polyvinylidene fluoride (PVDF) and other plastics according to the use conditions in the tower (such as temperature, pressure, media, etc.), it has a large void ratio, Low pressure drop and mass transfer unit height, high flooding point, full vapor-liquid contact, small specific gravity, high mass transfer efficiency. The use temperature in various media is 60-150 degrees Celsius, and it is mostly used in gas washing and purification towers.
The gap of this filler can have a higher amount of liquid retention, which can make the liquid stay in the tower for a longer time, thereby increasing the contact time of gas and liquid, and improving the quality efficiency.
