Annular Plastic Teller Rosette Ring for Water Treatment

Plastic teller rosette ring is also called plastic teller ring, plastic rosette ring. Plastic teller rosette ring has an annular design. Many small rings are arranged in radial direction inside of its ring-shaped structure. These small plastic rings have many joint points, which can enlarge the gas-liquid contact surface and time. Due to its high void rate and large flux, plastic rosette ring is not easy to plug. It has good resistance to fouling and plugging. Therefore, plastic teller ring performs well in mass transfer applications.
Plastic rosette ring has light weight, low pressure drop, low mass transfer unit height and low cost. It's applicable working temperature ranges from 60℃ to 150℃. Plastic teller rosette ring is available in different materials, shapes and sizes. It is fit for gas absorption, water treatment and purification. This type tower packing is commonly used in purification towers, cooling towers, washing towers and rectifying columns.

Quick Details

The rings in plastic teller rosette ring's internal side are available in different numbers.

Plastic Teller Rosette Ring – High-Efficiency Random Tower Packing

The Plastic Teller Rosette Ring, also known as the Plastic Teller Ring or Plastic Rosette Ring, is a high-performance random packing with an annular design. Inside its ring-shaped structure, multiple small rings are arranged in a radial direction, creating numerous joint points that maximize gas-liquid contact time and surface area. Due to its high void fraction and large flux, the Teller Rosette Ring is highly resistant to fouling and plugging, making it an excellent choice for mass transfer applications.

Key Features & Advantages:

Large Surface Area & High Void Ratio

Enhances gas-liquid contact efficiency for improved mass transfer performance.

Excellent Resistance to Fouling & Plugging

The open, self-cleaning structure minimizes blockages.

Low Pressure Drop & High Flow Capacity

Reduces energy consumption and improves tower efficiency.

Superior Chemical & Corrosion Resistance

Manufactured from PP, PE, PVC, PVDF, and other plastics, making it suitable for acidic and alkaline environments.

Lightweight & High Mechanical Strength

Injection-molded construction ensures durability, easy handling, and installation.

Applications of Plastic Teller Rosette Ring:

Gas Scrubbers & Air Pollution Control
Cooling Towers & Water Treatment Systems
Absorption & Stripping Towers
Chemical & Petrochemical Processing
Waste Gas & VOC Control Systems

Specifications:

• Material: PE (polyethylene), PP (polypropylene), RPP (reinforced polypropylene), PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride) and PVDF (polyvinylidene fluoride).

• Package: plastic bags, cartons.
