P-Pak™ Random Packing

Pall rings have cylindrical dimensions but punched rows of windows increase performance by increasing the surface area of the packing. They are suited for low pressure drop and high capacity applications. They have a degree of randomness and a relatively high liquid hold up, promoting a high absorption, especially when the rate of reaction is slow. The cross structure of the Pall ring makes it mechanically robust and suitable for use in deep packed beds.

⊕  Equivalent to the widely used Pall ring
⊕  Designed by BASF AG around 1940 based on the Raschig ring
⊕  Punched “shovels” leave “windows” on the outside, facilitating vapor flow and increasing capacity compared with the R-Ring
⊕  Extensively tested by research institutes worldwide
