MACH Hi-Rings have a cylindrical shape with an open structure that permits flow-through while still delivering mechanical strength. Our product features a large void space, which keeps the overall weight low enough to use in large-capacity towers without the need for intermediate packing supports.

Materials & Sizes

We manufacture our packing rings in 1/2″, 1″, 1 1/2″, 2″ and 3 1/2″ sizes. Larger MACH Hi-Rings packing has a larger percentage void fraction, lower geometric surface area and lower weight per square foot. Available materials include:

  • Polypropylene (PP)
  • High-density polyethylene (HDPE)
  • Polyvinyl chloride (PVC)
  • Corzan® (CPVC)
  • Kynar® (PVDF)
  • Teflon® (PFA)

A wide range of material options supports a wide range of potential applications. High-density polymers are suitable for use in higher temperatures, while low-density materials like PP are cost-effective general-purpose alternatives. For additional information, please contact us.

Benefits of MACH Hi-Rings

Our MACH Hi-Rings tower packing offers the following benefits:

  • High mechanical stability, very high void fraction and low overall weight
  • Excellent capacity for high gas and liquid flow rates, with extremely low pressure drops
  • Minimal sensitivity to pollution and fouling
  • A decreased tendency for liquid to migrate to the column wall
Applications for MACH Hi-Rings Tower Packing

Several industries use MACH Hi-Rings packing, including petroleum, chemical and environmental processing. MACH Hi-Rings are suitable for any application requiring large towers. Compared to Pall Ring alternatives like Plastic P-Rings and FLEXIRING random packing, MACH Hi-Rings can deliver higher flow rates and lower power consumption.

Also, the high mechanical integrity of our MACH Hi-Rings keeps maintenance requirements and costs to a minimum, while their light weight avoids the need for thicker tower walls. Polymer Hi-Rings are corrosion resistant and durable enough for use in harsh environmental conditions.
