Elegant Teller Rosette Ring - Controlled Interlock Design in Durable Plastic
Originating from the United States in 1954, and affectionately termed the 'Teller Rosette' in our domestic market, this innovative packing is a masterpiece of engineering. It consists of an intricate array of 12 small rings, artistically arranged radially to form a large, flat sphere akin to a spiral spring elegantly coiled into a spherical shape. Celebrated for its versatility, it is available in a series of three distinct models. Its standout attributes include an exceptionally high void fraction, robust resistance to clogging, substantial throughput capacity, and minimal resistance. The design allows for a high liquid holdup within its gaps, extending the liquid's residence time within the tower. This optimizes gas-liquid contact and elevates separation efficiency. Users have the flexibility to select from a range of materials such as Polypropylene (PP), Glass-reinforced Polypropylene (RPP), Polyvinyl Chloride (PVC), Chlorinated Polyvinyl Chloride (CPVC), and Polyvinylidene Fluoride (PVDF), based on the specific operating conditions of their towers, including temperature, pressure, and media type.

Designed for low pressure and high energy conditions, this product ensures exceptional efficiency in mass transfer. Users can tailor their choice of material from options like polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), or polyvinylidene fluoride (PVDF), depending on tower conditions such as temperature, pressure, and media. It boasts an impressive void ratio, minimal pressure drop, and optimal mass transfer unit height. With a high flooding point and complete vapor-liquid interaction, it offers a low specific gravity with superior mass transfer efficiency. These attributes make it ideal for use at temperatures ranging from 60 to 150 degrees Celsius in various media, particularly in gas washing and purification towers.
The innovative design of this filler, with its extensive gaps, allows for greater liquid retention. This prolongs the liquid's stay within the tower, thereby extending the gas-liquid contact time and significantly enhancing the efficiency and quality of the process.
