Metal rasching ring, whose height is same as diameter, has a simple hollow cylindrical shape. Designed by F.Rasching in 1914, metal rasching ring which was first invented is a kind of random packing in geometrical shape. Metal rasching rings in large size (great than or equal to 100 mm) are generally set and filled in towers neatly, while metal rasching rings in small size (less than or equal to 75 mm) are huddled in the packing towers. Because of its simple structure and light weight, it is easy to manufacture and operate. Working as a catalyst support, metal rasching ring is widely applied to many different fields.

Metal rasching ring can be applied to drying towers, absorption towers, scrubbing towers and regeneration towers in chemical, metallurgic, gas and oxygen generation industries, etc.
