Ceramic Pall ring is a type of classical random packing which is developed from the Raschig ring and with two layers of windows opened along its tube wall. Each layer has five ligules bending inward the axes of the ring, which is similar to the metallic pall ring and plastic. But the layer and quantity of ligules may different according to the height and diameter variation.
Ceramic Pall rings offer good mechanical strength as well as a non-porous surface. Ceramic is inert and iron-free, and, as a result, they won’t rust or react when used with harsh chemicals.
Good mechanical strength and resistance to high temperatures
Excellent resistance to acids, alkali, salts and various organic solvents
High heat endurance
Minimal pressure drop, with even liquid and gas distribution
Cost-effective performance
Ceramic Pall ring is a type of classical random packing that finds its use in the drying columns, absorbing columns, cooling towers, scrubbing towers and actifier columns in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc.
