Hold Down Plates/Bed Limiters
Retaining devices are used to avoid bed movement in the event of a pressure surge or a major uprising. They will minimize damage of packing and avoid particles fluidization and carrying over.
The structural components of each bed limiter are designed to minimize the interference of the liquid flow from the distributor
The method of attachment to the tank is specific for each type of bed limit, this can be fixed on the column, or attach on the top distributor
Bed limiters for structured packing are recommended when there is a risk of perturbation that can move the packing.
