Pall Ring-2

“Pall Ring-2” typically denotes smaller diameter Pall Rings. For example, 25 mm, 38 mm, and 50 mm OD rings. These small rings offer very high packing factor, meaning more surface area per unit volume than larger rings. They are ideal where capacity is lower or where liquid distribution must be extremely fine.

Key Features

Miniature Sizes: As small as 25 mm diameter, offering extreme surface area (e.g. 205 m²/m³ for a 25 mm ring).
Enhanced Gas-Liquid Contact: High void fraction (~86–92%) still maintained.
Material: Plastic or even metallic versions for high-temperature use.

Benefits

Fine Control: Great for vacuum distillation or small-scale absorbers.
Uniform Distribution: Liquid spreads quickly across many rings due to small channels.

Applications

Laboratory Columns: Small distillation or extraction columns.
Reflux Systems: Where precise separation is needed.

Technical Specifications

Example Data (25 mm): Surface ~205 m²/m³, voidage ~86%, packing factor ~137.
Sizes: Common: 25, 38, 50 mm diameters (others available).

Unique Selling Points (USPs)

Maximized Area: The highest mass transfer of any Pall Ring due to small size.
