Overview of Jaeger Tri-Packs®
MACH plastic Tri-Packs® tower packing provides reliable performance in a variety of industrial mass transfer and separation processes. Tri-Packs — introduced in the 1980s and since recognized for their notable sphere shape — are a type of media used in random tower packing, which is a method of purifying gas and liquids. Use them for distillation, scrubbing, degasifying, stripping and more. Random tower packing media come in numerous shapes, though Jaeger Tri-Packs® are highly functional and offer maximum surface contact. They are used to create a larger surface area for contact between vapor and liquid. The contact makes separating chemicals more efficient.
Small packing matter is randomly distributed to help during the separation process. They guide liquids through the packing media into fixed shapes. Tri-Pack tower packing is one of the most efficient tower packing media, allowing you to reach high rates of mass transfer. With higher efficiency, this packing type can also help lower operating costs.
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 hollow, spherical shape for random packing 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 include their lower pressure drop and high mass transfer rates. Its manufactured from injection-molded plastic and select materials meet NSF® standards for potable water use. For more information, get in touch with MACH Engineering directly.
When choosing a tower packing media, it’s important to consider whether its performing factors will be suitable for your application. For example, the above characteristics make Tri-Pack packing ideal for strippers, scrubbers and degasifiers.
Benefits of Tri-Packs
The design of Tri-Pack tower packing provides several benefits, especially when compared to other options. Some of the benefits of this tower packing include:
- Its spherical shape offers an effective surface area to void space ratio — more than the Pall Ring — resulting in a high active surface area.
- The unique struts, drip rods and ribs allow Tri-Pack scrubber packing to keep uniform liquid distribution across the bed.
- It confers extremely low pressure drops and maximizes the operating capacity.
- Tri-Packs prevent compression interlock and dry spots that cause air and liquid channeling, which are common among more traditional packing methods and decrease efficiency.
- Because Tri-Packs don’t have flat surfaces or small openings for particles to get trapped, there is virtually no nesting or settling, which makes the removal and the installation of this packing easy.
- Additionally, without valleys and corners, puddling is eliminated and wasteful liquid flow is reduced.
- The round Tri-Pack generates predictable performance data which helps to design the column.
- The circular and consistent design of each packing helps achieve high mass transfer and heat transfer rates.

More generally, Tri-Packs tower packing can be used in several applications across many industries. They are most commonly used in water and air pollution services and applications. For example, scrubbing, distillation, air stripping, biological treatment, mist elimination, gas and liquid separation, and cooling towers are some of the most common mass transfer applications for Tri-Packs.
Tri-Packs packing media are also used with a variety of MACH Engineering products like Fume Scrubbers, Distillation Towers and Air Strippers. Tri-Packs can be used in processes like ammonia stripping, NOX scrubbing, CO2 degassing, steam stripping, oxygen deaerating and more when working with various other air pollution products and services.
Whether you’re trying to optimize performance in an existing tower or designing a new system from the ground up, you’ll save money and get the benefit of working with a dedicated partner by choosing MACH.
