Product Description
ceramic lessing rings are 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. 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 lessing one ring as an important heat transfer media, used in the heat transfer system, regenerative oxidisers system (RTO ).
