MACH plastic Tri-Packs tower packing provides reliable performance in a variety of industrial mass transfer and separation processes. Use them for distillation, scrubbing, degasifying, stripping and more. MACH can supply products in different sizes for nearly any applications.

Compared to older types of tower packing, Tri-Packs — which were first developed in the late ’70s and came to find broad acceptance throughout the next decade — have multiple advantages. Their unique spherical shape prevents nesting and settling, while a network of interior ribs maximizes surface area and helps ensure uniform liquid distribution. This, in turn, improves wetting qualities without impeding gas and liquid contact.

Other benefits to Jaeger Tri-Packs Tri-Packs include their lower pressure drop and high mass transfer rates. Manufactured from injection-molded plastic, they are corrosion- and temperature-resistant. Select materials meet NSF standards for potable water use. For more information, get in touch with MACH Engineering directly or view our Tri-Packs product specification sheet.
