Tellerette packing ring is also called teller ring and tellerette rosette ring. It is well known for its economical and versatile performance characteristics because of its unique annular helix design. This design increases its surface area and the contact between the falling liquid and the rising vapor. And it is more efficient in mass transfer than traditional packing.
Tellerette ring has excellent heat transfer efficiency and mass transfer characteristics in gas absorption, air conditioning, etc. Tellerette Ring is widely used for high corrosion resistance and low pressure drop packing in gas absorbers, cooling towers, deaerators, and reaction gas-liquid contact systems.
Tellerette Ring Types and performance
Tellerette Tower Packing is available in different materials such as metal and plastic including polyethylene(PE), polypropylene(PP), reinforced polypropylene(RPP), and polyvinyl chloride(PVC), chlorinated polyvinyl chloride(CPVC), and polyvinylidene fluoride(PVDF) based on different application requirements.

Tellerette Ring Benefits
Advantage:
1. High free volume. Its design provides a large effective surface area per unit packing volume
2. Low pressure drop cuts operating costs. Pressure drop was reduced through filament shape with large void space, therefore the fans or blowers consume less electrical power
3. Larger gas flow capacity, allowing the use of smaller diameter columns at a significantly lower cost
4. High mass transfer efficiency. Retrofit existing towers to increase efficiency and capacity
5. The gas-liquid contact is uniform due to its curvilinear structure and a large number of branches and connections
6. High open area design to reduce dirt
7. Low mass transfer unit height, high flood point
8. Better particle collection by inertial impact
9. High column stability - no classic flooding
Application Of Tellerette Packing
Subject
Gas absorption: SO2, SO3, NH3, CO2, H2S, HCl, Cl2, HF, NOX, organic solvents
Stripping: NH3, CO2, O2, trihalomethane-contaminated water, water containing organochlorine compounds
Cooling: air cooling (liquefaction) and water cooling
