Ceramic Mini Lessing Ring

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).
