Ambani Metals is a leading manufacturer, supplier and exporter of Metal VSP Ring, Plastic VSP Ring, Random Packing in India.
A VSP Ring (Vertical Spiral Ring) is a type of high-efficiency random tower packing designed to maximize gas–liquid contact while maintaining very low pressure drop inside packed columns. It is commonly used in chemical processing, petrochemical industries, gas absorption, and environmental treatment systems.
A VSP Ring is an advanced random packing component featuring a vertical spiral structure with multiple openings. This design increases the effective surface area and improves fluid distribution, making it far more efficient than traditional Raschig Rings or Pall Rings.
Its geometry allows liquids to spread evenly, while gases pass smoothly through the packing bed with minimal resistance, resulting in excellent mass transfer efficiency.

Metal VSP Ring (Very Special Packing)
At Ambani Metals, we manufacture and supply premium-quality Metal VSP Rings, also known worldwide as Mella Rings or Inner Arc Rings. This advanced random tower packing is engineered to provide exceptional hydraulic performance, superior mass transfer efficiency, and excellent stability in demanding process environments. With its unique floral-hoop-style design and optimized geometry, the Metal VSP Ring is one of the most efficient metal packings used in chemical and petrochemical industries.
Innovative Design for Maximum Performance
The Metal VSP Ring features a highly symmetrical geometric structure created by folding inner arcs equally along the axial direction. These arcs are alternately arranged to form a continuous curved surface. This design provides:
- Large open area along the ring wall
- Higher liquid and gas throughput (large flux)
- Low pressure drop even at high loads
- Even gas-liquid distribution
- Excellent mass transfer efficiency
Thanks to its innovative internal structure, the Metal VSP Ring minimizes turbulence, enhances surface utilization, and ensures uniform flow across the packed tower.
Key Features & Benefits of Metal VSP Rings
- Very high surface exposure due to continuous arc design
- Low resistance and reduced pressure drop, improving operational efficiency
- High mass transfer performance for absorption, stripping, distillation, and scrubbing
- Uniform liquid distribution, preventing channeling and dry spots
- High mechanical strength, ideal for deeper packed beds
- Increased throughput, suitable for revamping existing towers for better capacity
- Excellent performance under high temperature and corrosive environments depending on material choice
These advantages make the Metal VSP Ring a preferred choice for industries requiring consistent, high-efficiency tower packing systems.
