Ceramic Cross Ring


Ceramic Cross Ring is improved by ceramic raschig ring, with better surface area and compressive strength than raschig ring, with 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. Ceramic Cross Ring 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.
