Spherical Style Packing
Tripacks is a hollow spherical column packing constructed of a unique network of ribs, struts, and drop rods. Plastic Tripacks are distinguished from other packing by its superior geometric shape.
Their spherical shape allows each element to roll into the “packed position” without forming void areas common to irregular shaped packing or those with excessive pins and appurtenances. With Tripacks, there is no need for allowances for settling and nesting is virtually impossible. The round Tripacks offers reliable and predictable loading of your tower which means reliable and predictable performance. In addition to the superior geometric shape, an active surface area is vital to mass transfer.
The unique network of ribs, struts and drip rods have proven to give the Tripacks a distinct advantage in providing excellent wetting qualities and maintaining liquid distribution through the packed bed. Some suppliers claim more surface area, but surface area alone is not an indication of performance. Excessive surface area can impede proper gas and liquid contact and always results in higher pressure drop which increases horsepower requirements and operating costs. The Tripacks offers an optimum surface area to open area ratio which yields excellent mass transfer efficiency and reduced operating costs.
Tripacks are available in three sizes, 1”, 2”, and 3.5”. Kempac products uses only prime, virgin resins and no recycled materi- als are ever used. Almost any injection moldable resin is available; the most common include PP, PE, PP-G, CPVC, Noryl, Kynar®, Halar®, Teflon® and many more. Tripacks made of Polypropylene (PP) have been certified by NSF to Standard 61 for water treatment plant applications.
