![Stainless Steel, Copper, Bronze Dixon Ring](images/mass-transfer-equipments/dixon-ring.jpg)
Dixon Ring
Dixon Ring also called packing ring, is made of stainless steel and other metallic wires. Weave the metal wires into rolls and then cut them into specified strips. Roll up the strips and form the Dixon Ring. The diameter of Dixon Ring is same as the height, which can supply high performance.
Application
- The Dixon ring is widely used in laboratory and low-volume, high purity product separation process.

![Canon Ring](images/mass-transfer-equipments/canon-ring.jpg)
Canon Ring
Canon Ring has similar sizes with dixon ring, which is small but highly efficient. It is commonly made from stainless steel. Also, it can be made from Monel and other materials for excellent corrosion and rust resistance performance. Stainless steel or other metal plates are perforated into several tiny holes. As the points of the die push passing through the metal, jagged burrs are formed on the reverse side of the plates. The tensile strength is higher than other laboratory packings.
Application
- Suitable for laboratory and high purity products distillation towers
- Unique wetting process and high filtering efficiency
- Atmospheric and reduced Pressure environments

VSP Ring
The VSP ring, also known as the inner arc ring or very special packing, is typically made from stainless steel materials like 304, 321, and 316. These rings have a neat geometric pattern where the inner arcs are evenly folded along the length and arranged alternately. This creates a smooth surface with lots of space inside and ensures even distribution of fluids. Compared to pall rings, VSP rings can handle higher flow rates, about 15% to 30% more, and they cause less pressure drop, which can be reduced by 20% to 30%.
Features
- Reasonable geometric symmetry
- Evenly gas and liquid distribution
- High mass transfer performance
- 15%–30% Increased flux
- 20%–30% Reduced pressure drop
Material
- Stainless Steel 316/L, 304/L, 410, Inconel, Monel, Hastelloy, Carbon Steel, etc.
Application
- Petrochemical, fertilizer, environment protection, sugar refinery and other industries. It is widely used in the synthesis ammonia desulfuration, decarburization and other large devices

It has openings on the packing wall that make up more than 50% of the surface area, allowing for better flow. It also has a higher void fraction than the pall ring. Moreover, it can handle more flow than the pall ring while causing much less pressure drop, which is about 45% lower. Inside, there are two layers of blades arranged in a staggered pattern along the wall, and there are reinforced ribs in the center of the wall to make it stronger.

![Teller Rosette Ring](images/mass-transfer-equipments/Teller-Rosette-Ring.jpg)
Teller Rosette Ring
The Teller rosette ring is made of either metal or plastic. The metal version has twelve small rings arranged radially, while the plastic version can have a different number of small rings. For plastic, there are usually ten or other amounts arranged in a radial direction. This unique design gives the Teller rosette ring a large empty space inside, prevents clogging, allows for high flow rates, and reduces pressure drop. Because there's a lot of space for fluid in between the rings, it slows down the flow of liquid, gives more time for gas and liquid to mix, and improves how efficiently substances are transferred.
Features
- Large void fraction and low pressure drop
- Fully contacting of liquid and gas
- Temperature and corrosion resistance
- Non-jam and large flux
Material
- Stainless Steel 316/L, 304/L, 410, Inconel,Monel, Hastelloy, Carbon Steel, etc.
- Plastic - PE, PP, PVC, PVDF, CPVC, RPP.
Application
- Plastic teller rosette ring. Media temperature ranges from 60°C to 150 °C. Gas washing and purifying towers
- Metal teller rosette ring. Vacuum distillation, coal gas dehydrators and other column towers.
