Hiflow Ring
Hiflow® rings are a high-performance plastic tower packing product capable of delivering minimal pressure drops and excellent durability in a range of industrial applications. Multiple sizes and configurations provide options for every customer, while an accessible price point makes our product an economical choice, as well.
Product Details
Hiflow 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.
We manufacture our packing rings in 1/2″, 1″, 1 1/2″, 2″ and 3 1/2″ sizes. Larger Hiflow 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.
| Nominal Size (in) | 1/2 (15 mm) | 1 (25 mm) | 1-1/2 (38 mm) | 2 (50 mm) | 3-1/2 (90 mm) |
| Void Fraction (%) | 91 | 92 | 94 | 94 | 96 |
| Geometric Surface Area (ft2/ft3) | 95.4 | 65.2 | 45.7 | 33.5 | 23.2 |
| Weight – PP (lb/ft3) | 5.0 | 5.3 | 3.2 | 3.1 | 1.7 |
Benefits of Hiflow Rings
Our Hiflow® 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 Hiflow Tower Packing
Several industries use Hiflow packing, including petroleum, chemical and environmental processing. Hiflow rings are suitable for any application requiring large towers. Compared to Pall Ring alternatives like Plastic P-Rings and FLEXIRING random packing, Hiflow can deliver higher flow rates and lower power consumption.
Also, the high mechanical integrity of our Hiflow 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.
