Random column packing is packaged and shipped by volume. A volume adjustment factor must be applied to the calculated column. Geometric volume to estimate the shipping volume required to properly fill a packed bed to account for edge and settling effects. The volume adjustment factor depends upon the packing shape and size and the bed diameter.

A contingency allowance for installation losses, typically around 5%, should be added to the shipping volume calculated above.

Strict conformity with recommended installation procedure is necessary to ensure consistent duplication of design performance. Installation techniques that result in installation crew walking on or raking the packing must never be employed. Incorrect installation procedures can result in substantial packing shortfall (i.e. installed volume not sufficient for the required bed height resulting in performance losses).
