SUPERFRAC® XT Tray

In larger diameter columns, typical multi-pass designs are limited to four passes. For applications that require more than four passes, the proprietary multi-pass downcomer design can be used to reduce weir loading and improve the capacity of the column.  

Koch-Glitsch has successfully designed large diameter columns that use multi-pass design techniques in 6-pass or 8-pass configurations. The downcomer configuration for a multi-pass design typically is the multi-chordal design; however, almost any other configuration can be used.
