Performance Considerations
For 1” and larger packings, the bed limiter, in its simplest form, consists of a grid of flat bars welded to a ring. The spacing of the bars determines the percent open area. The normal pressure drop across this type of bed limiter is less than 75 Pa.
All types of bed limiters can be supplied in sections to allow easy installation through access manways.
Additional support beams should be considered in larger towers to provide the necessary structural support.
