Plastic FLEXIRING® Random Packing and plastic SuperINTALOX® Saddles have been used for many years andhave become the standard for many designers and process-es. Although these packings do not have the "high perform-ance" characteristics of INTALOX SNOWFLAKE or β-ETARING packings, they have been used extensively and there-fore their performance is widely known. Further, they areless sensitive to liquid distribution quality and have higherliquid hold-up and residence time for those services thatbenefit from such characteristics.

Generally, Super INTALOX Saddles are favored by designers and industries that once used ceramic saddles but now wantthe superior performance of plastic Super INTALOX Saddles.

FLEXIRING random packing is favored by designers andindustries that prefer metal FLEXIRING packing and othermetal packings but now need the corrosion resistance ofthe plastic construction.

Koch-Glitsch offers two enhanced performance versions ofFLEXIRING random packing: The 2-inch [50 mm] and 4-inch[100 mm] High-Performance FLEXIRING random packing.Extra vanes inside each of these rings produce more effi-ciency than their standard counterparts, without sacrificingany capacity. These two packings can be useful when adesigner wants maximum efficiency from a 2-inch [50 mm]FLEXIRING packing or extra capacity then a 3.5-inch [90mm] FLEXIRING packing.
