Metal bulk packing
Triangle Spiral packing, also known as triangle packing, belongs to the Fenske packing (Fenske Spiral), is made of metal wire winding, its shape is similar to the spring, so it is also called triangle spring packing, the difference between it and the spring.
Each circle is not a circle but a triangle, and the triangles between the circles are staggered at a certain Angle. So it's a polygon from the end. This kind of filler is more efficient, but compared with θ ring filler, it has higher separation efficiency and slightly greater resistance. It is mainly used for isotope separation and extraction in laboratory, especially in the field of nuclear industry. Equal plate height (H.E.T.P) is in the range of 25 ~ 58mm.
