Stainless steel rolling hole ring filler is a small particle high-efficiency filler made of metal sheet, with a diameter equal to its height.

Rolled hole ring packing is mainly used in the separation process of laboratory and small batch, high-purity products. Its strength is greater than other laboratory fillers.

Due to the above characteristics, the equal plate height of the rolled hole ring network packing is small, its resistance is also small, and the solid and pressure drop are also small. In addition, due to the high surface infiltration rate and large liquid holding capacity per unit volume, but due to the small theoretical equal plate height, this characteristic is very suitable for distillation. And due to the piercing of the rolled hole ring, the liquid surface is sufficiently uneven, which is also conducive to mass transfer process and shortens the time required to reach gas-liquid equilibrium.
