Key Features
- Enhanced Geometry: Slotted walls with curved “petals” improve liquid distribution over the entire surface.
- High Surface Area: Even small sizes yield around 90–95 m²/m³.
- High Voidage: Typically very open (over 90% void fraction) to allow high throughput.
- Stable Packing Factor: Designed to self-lock and resist collapse, maintaining consistent performance.
Benefits
- Improved Efficiency: Better gas-liquid mixing than standard rings, leading to higher separation efficiency.
- Low Fouling: Open design resists clogging, ideal for dirty or viscous fluids.
- Ease of Handling: Lightweight plastic rings, easy to fill or dump from a column.
Applications
- Distillation Columns: Where maximum efficiency is needed at moderate pressures.
- Absorption Towers: Capturing contaminants or scrubbing gases with minimal resistance.
- Chemical Processing: Fractionation of specialty chemicals where fine separations are required.
Technical Specifications
- Materials: Commonly PP or PE (sometimes PVDF for high chemical resistance).
- Sizes: Standard diameter e.g. 1″, 2″, 3½″.
- Packing Factor: About 28 (dimensionless) for 1″ rings, dropping as size increases.
Unique Selling Points (USPs)
- Maximum Contact: Outperforms standard Pall Rings in efficiency due to complex surface shape.
- Versatility: Works in applications ranging from vacuum distillation to high-pressure absorption.
