Metal Pall Rings

Metal Pall Rings are one of the most common and well known packings, Alto's Metal Pall Ring is produced to an industry standard design and is used widely in all variety of applications.

 By minimizing the number of contours and crevices that can cause liquid hold-up and potential entrainment, Alto's Metal pall ring enables high gas and liquid transfer rates. The opened cylinder walls and inward bent protrusions allow greater capacity and lower pressure drop than standard Raschig Rings. This open ring design also maintains an even distribution and resists wall-channeling tendencies. The interior and exterior contacting surfaces provide for an effective distribution of liquids and gasses and resist plugging, fouling and nesting.

Pall rings are available in a wide range of materials like steel, stainless steel, Aluminun and special alloys like Monel 400 and Inconel.
