Description

Ceramic super saddle random tower packings (column packing) have excellent acid resistance and heat resistance. They can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature conditions. Consequently their application ranges are very wide. The packings can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc.
