Large Active Surface Area Plastic Tri Pack Media For Biological Filtration
Plastic Tri-Packs is a hollow spherical shaped packing made of injection moulded plastic in four sizes: 1”, 1 1/4”, 2”and 3 1/2”diameter.
Its symmetrical geometry made from a unique network of ribs, struts and drip rods yields unprecedented performance. It has high void space, greater than packings of comparable size, and achieves superior pressure drop values, up to 90% reduction, as compared to other products. The packing has a high ACTIVE surface area, exposing all of its surface area to be fully wetted during column operation. The performance capabilities of plastic Tri-Packs have resulted in significant savings in hundreds of packed column operations.
Materials: Polypropylene(PP), Reinforced Polypropylene(RPP), Polyethylene (PE), Polyvinylchloride (PVC), Corzan (CPVC), Kynar (PVDF)Reinforced Nylon 6, Reinforced Nylon 66, …
