Ceramic Raschig rings have excellent acid resistance and high heat resistance. They resist the corrosion of inorganic and organic acids (except hydrofluoric acid) and organic solvents. They can be used in both high and low temperature conditions. Thanks to these properties, they are used as filling in drying columns, absorption columns, cooling towers, washing towers and activator columns in the chemical industry, metallurgical industry, coal and gas industry, oxygen producing industry, etc. Used material C111 ensures their dimensional stability and long service life.
