Modern Teller Rosette Ring - Durable Plastic with Interlocking Design Feature
Introduced by the United States in 1954 and affectionately known as 'Teller Rosette' in local markets, this innovative packing design boasts 12 small rings strategically arranged to form a large, flat sphere akin to a spirally coiled spring. This has evolved into a versatile, serialized product line featuring three distinct models. Distinguished by its high void fraction, impressive resistance to clogging, substantial throughput, and minimal resistance, this product optimizes efficiency. The enhanced liquid holdup within the gaps enables extended liquid residence time within the tower, significantly boosting gas-liquid contact and separation efficacy. Users are offered a selection of premium materials including Polypropylene (PP), RPP (Glass-reinforced Polypropylene), Polyvinyl Chloride (PVC), Chlorinated Polyvinyl Chloride (CPVC), and Polyvinylidene Fluoride (PVDF), tailored to suit various tower operating conditions such as temperature, pressure, and media requirements.

Engineered for low pressure and high energy efficiency, this product delivers superior mass transfer capabilities. Users can select from a variety of materials like polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polychlorozene (CPVC), and polyvinylidene fluoride (PVDF) based on the specific operational conditions within the tower, such as temperature, pressure, and media. The product's design includes a large void ratio, low pressure drop, minimal mass transfer unit height, high flooding point, comprehensive vapor-liquid contact, low specific gravity, and exceptional mass transfer efficiency. It operates effectively within a temperature range of 60-150 degrees Celsius across various media and is particularly suited for applications in gas washing and purification towers.
The unique structure of this filler allows for an impressive liquid retention capacity, enabling the liquid to remain within the tower for extended periods. This prolongation of the contact time between gas and liquid significantly enhances the efficiency of the process, delivering outstanding quality results.
