Cascade Mini Ring high-performance random packings provide significant capacity advantages and lower pressure drop than other random packings. These high-performance random packings have consistently demonstrated capacity improvements of up to 15% in a variety of applications without loss of efficiency. Superior mechanical integrity allows processors to specify deep beds without packing deformation. Both high performance packings are available in several sizes and virtually any metallic material. Cascade Mini Ring random packings are the most advanced random packing designs offered today. Low Aspect Ratio (1/3 to 1/2 of H/D)- Key to Highest Performance for Mass Transfer. Cascade Mini Ring is the successful third-generation random packing. Since its introduction, CMR random packing has been utilized in a wide variety of distillation, absorption and stripping columns around the world. The superior performance of CMR random packing has been shown in thousands of successful installations.
