Plastic Raschig Ring with PP/PE/CPVC
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.
