The spherical shape of the Top-Pak metal packing ensures more uniform liquid distribution, even at low spray densities and greater filling heights. The column has a favorable, moderate fouling tendency and is easier to clean, even when heavily contaminated. It offers an optimal number of separation stages with low pressure losses. Top-Pak metal packing is available in stainless steel 304, 316, 316L, AISI 316 TI, copper, and other materials upon request.
