The design of Raschig Super-Ring^® was published in 1998 and had set a new standard in the performance of random packings. Nowadays it is called the first fourth generation random packing compered to earlier designs like Raschig-Rings, Pall-Rings and IMTP^® packings. Soon after the Raschig Super-Ring^® was available to the industry it was a new reference line for packing comparisons in terms of pressure drop, capacity and efficiency. Raschig Super-Ring^® Plus is the result of a consequent design development based on many years of research. The target was to stay with all advantages of Raschig Super-Ring^® but improve capacity and reduce pressure drop.
