 Pall ring is one of the most common and well known packings, Pall Ring is an industry standard design media developed from the Raschig Ring 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, pall ring geometry enables high gas and liquid transfer rates. The opened cylinder walls and inward bent protrusions of the pall Ring allow greater capacity and lower pressure drop than standard cylindrical rings. This open ring design also maintains an even distribution and resists wall-channeling tendencies. The interior and exterior contacting surfaces of the pall ring packing 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.
