Triangular Spiral Packing

Also known as Triangular Packing, it belongs to the Fenske Spiral packing family. It is manufactured by winding metal wires into a shape similar to a spring, leading some to refer to it as "Triangular Spring Packing." The key difference from a standard spring is that each coil is triangular rather than circular, with the triangles offset at specific angles between successive loops. Consequently, the cross-sectional view appears as a polygon. This packing offers high efficiency; compared to θ ring packing (Dixon ring), it provides superior separation efficiency but with a slightly higher pressure drop (resistance).
