Tellerette Ring

25mm Plastic Rosette Ring

Plastic Rosette Ring packing, also known as Plastic Tellerette Ring, is A type of packing that resembles a large flat sphere in shape. It is usually composed of 12 small rings arranged radially. Some products have small circles in the shape of an A, with teeth along the edges or no large outer circle. Customers can order different types according to their needs.

Plastic Rosette Ring Properties

High mass transfer efficiency

The liquid holding capacity in the voids is high, which can prolong the liquid residence time in the tower and increase the contact time between the gas and liquid phases.

Excellent fluid mechanics performance

It features a large void ratio, low pressure drop and mass transfer unit height, high flooding point, large flux, and low resistance.

Not prone to clogging

The structural design can prevent dead corners where downstream liquids flow, making the liquid distribution more uniform.

Products advantages

Specific surface area: High (e.g., 100-200 m²/m³), providing ample contact area for mass transfer.

Porosity: High (e.g., 90%-95%), minimizing gas flow resistance and reducing pressure drop.

Pressure drop: Low pressure drop makes it suitable for handling large gas flows and reducing tower equipment energy consumption.

Corrosion resistance: Plastic materials (e.g., PP and PE) are resistant to corrosive media such as acids, alkalis, and salts, making them suitable for use in chemical and environmental protection applications.

Temperature resistance: Generally, the temperature range is -20°C to 120°C (depending on the plastic type, e.g., PP is approximately 110°C, PVC is approximately 60°C).
