Product Description

Metal Rasching Rings are a type of random tower packing suitable for high-capacity and high-performance applications.

The design of the Raschig ring was invented by Friedrich Raschig and patented in 1914. The Raschig ring is a simple cylindrical shaped tube with an aspect ratio of 1:1. The aspect ratio is defined as the ratio between the height and the diameter of the Raschig ring.

Raschig’s design changed the market: the Raschig rings tremendously improved the performance of a column. Promoting contact between vapor and liquid phases, while minimizing liquid holdup of the column. Raschig rings are long lasting and cost effective, therefore still used today for many applications of mass transfer, preferentially however, for refilling existing columns.

Choosing the correct size is crucial for both flexibility and safety.
