Saddles Pall Ring

Saddles (also known as Intalox Saddles) are tower packing elements shaped like a saddle or dish. The “Saddles Pall Ring” combines features of saddle and ring packings: it has saddle-like curves with ring-like openings, offering a very high number of liquid flow points. This hybrid design yields very large surface area and voidage, along with mechanical strength.

Product Inquiry

Key Features

Unique Geometry: Blends saddle and ring shapes, presenting liquid to gas in multiple directions.
Very High Voidage: Often above 90%, ensuring low pressure drop even at high flows.
Robust Structure: Often with thicker walls or support ribs for column height stability.

Benefits

Low HETP (Height Equivalent to Theoretical Plate): Excellent efficiency even at low liquid flow rates.
High Turn-Down Capability: Handles wide flow range without loss of performance.
Mechanical Strength: Suitable for packed beds under pressure (e.g. vacuum or high-pressure columns).

Applications

Vacuum Distillation: Where low pressure drop is critical.
High-Pressure Absorption: Petrochemical or gas treatment columns under pressure.

Technical Specifications

Material: Usually pressed metal or molded ceramic/PP.
Voidage & Surface: Example from MTPI: very large transfer points with very high voidage.

Unique Selling Points (USPs)

Versatile Performance: Works effectively in applications demanding both low and high gas flows due to its hybrid design.
