Overview

The Raschig Ring is a cylinder of equal length and diameter used as radom tower packing in a variety of chemical processes and mass transfer applications.  Wisconsin Stamping manufactures Rachig Rings in a wide range of sizes designed to meet any application and from a variety of metals, including carbon steel, stainless steel, aluminum, copper, inconel and various alloys.      

The quality and consistency of Raschig Rings is critical to optimal function and performance in any separation process.  While it may appear that there is no difference in the operating characteristics of rings produced by particular manufacturers, this is not the case.  Both quality and operating characteristics vary widely among manufacturers of Raschig Rings.  Wisconsin Stamping produces the highest quality and most consistent rings in the industy.

History of the Raschig Ring

Before the invention of the tower packing shape by Frederick Raschig, packed columns were filled with quartz, broken glass bottles, broken pieces of pottery, or coke. Operating data obtained from one tower could not be used in a second tower as the packing material was not consistent.

The invention of the Raschig Ring gave the packed column consistency and dependability. Raschig Rings significantly improved the operating characteristics of the column, enabling the performance of the packed column to be duplicated in a second column of equal size.

Because of their low cost, Raschig Rings remain one of the most widely used tower packing materials.
