Ceramic mini Lessing ring is improved by ceramic raschig ring,with better surface area and compressive strength, excellent acid resistance and heat resistance. It is usually used extensively for the supporting packing at the bottom of tower.
Ceramic Lessing ring has high desity and excellent heat and acid resistance and it withstands the corrosion of various inorganic acid, organic acid and organic solvents except fo hydrofluoric acid.
Ceramic mini Lessing ring, as an important heat transfer media, can be used in the heat transfer system, regenerative oxidisers system (RTO).
High chemical stability and high acid resistance
Excellent heat resistance
High specific surface area and low cost
High mechanical strength
Low pressure drop and high mass transfer efficiency
With excellent acid resistance and heat resistance, ceramic mini lessing ring is widely used as supporting packing at the bottom of packed columns, such as drying columns, absorbing columns, cooling towers, scrubbing towers in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc.
