Ceramic lessing ring is a packing designed basically from the raschig ring with partitions inside to increase the surface and enhance the transfer efficiency. It is usually used extensively for the supporting packing at the bottom of tower. It has high density and excellent acid resistance and it withstands the corrosion of various inorganic acid, organic acid and organic solvents expect for hydrofluoric acid.

The ceramic lessing ring has high density and excellent acid and heat resistance, and can resist corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid. Ceramic inline ring is a kind of ceramic random packing, which has the advantages of large flux, pressure drop and high efficiency.
The ceramic lessing ring can be used in drying towers, absorption towers, cooling towers, washing towers, regeneration towers, etc. in chemical, metallurgy, gas, environmental protection and other industries.
