Metal nutter ring, also called metal nutter ring packing, is a kind of new developed packing, which has a shape of saddle. Besides, there is a flanging reinforced rib with several holes on the back of the saddle. The metal nutter ring can be made from carbon steel, aluminium alloy and stainless steel SS304, SS304L, SS316, SS316L.

Compared with other packing rings such as metal cascade mini ring and metal pall ring, the metal nutter ring has the features of large flux, low pressure drop, high mass transfer efficiency, high operation elasticity and other advantages. Two semicircular rings of different sizes can help transverse the diffusion of liquids and renewal on the liquid surface so as to increase high surface utilized ratio. The metal nutter ring provides superior surface utilization allows for shorter packed beds and it is broadly applied to drying tower, washing tower and absorption tower.
