The BT Series Hold Down Media has been developed for use as a highly inert hold down material used at the top of graded reactor beds. The benefits of this media are high void fractions, surface area, and trapping qualities in both liquid and gas phase applications. BT-500, 750 and 1000 are an integral part of the reactor loading using ring shaped medallion for improved pressure drop control, and liquid vapor distribution.
