Metal Random Packing

High-strength, industry-standard random packing developed from the plain Raschig ring. Two rows of punched windows with inward-folded fingers give greater capacity and lower pressure drop, with uniform gas/liquid distribution and robust strength for deep beds and high-temperature service.

• Stainless steel — 304 / 316 / 316L
• Carbon steel
• Aluminum · titanium · bronze
• Special alloys including Hastelloy

Applications: absorption, aeration, degassing, desorption, distillation and stripping; H₂S / NH₃ / SO₂ absorption and stripping, steam stripping, quench towers, direct-contact cooling

A higher-performing evolution of the standard Pall ring. Additional internal twists and bends add interior surface — roughly 25–30% more mass-transfer points per m³ and over 10% higher capacity than a standard Pall ring, with lower pressure drop and liquid distribution that eliminates wall channeling.

• Wide range of metals and alloys — grade to order

Applications: gas dehydration, demethanizing, tall-oil fractionating, CO₂ removal, high-vacuum distillation, vacuum crude stills, H₂S contacting, liquid/liquid contacting

The original random-packing geometry — a plain cylinder of equal height and diameter. One of the largest surface areas among tower packings, handling heavy loading, process upsets and temperature shocks with exceptional stability. Simple, robust construction with no internal features.

• Wide range of metals and alloys — grade to order

Applications: petrochemical distillation and extraction, absorption in gas processing and combustion plants, desorption in water treatment

A saddle-and-ring hybrid combining the advantages of both geometries. Delivers roughly 30% lower pressure drop than Pall rings while keeping high efficiency and low liquid hold-up, allowing shorter beds. Monolithic construction resists end deformation; effective at both deep vacuum and high pressure.

• Copper · aluminum · bronze
• Hastelloy · titanium · zirconium

Applications: distillation and absorption; deep-vacuum towers where low pressure drop is critical, and high-pressure towers where capacity exceeds conventional trays

A low aspect-ratio ring (H/D ≈ 1/2–1/3) that raises capacity and cuts pressure drop versus standard rings. Preferential vertical orientation keeps the gas path open; highly exposed surfaces create efficient contact at many drip points. More fouling-resistant than taller rings and strong for deep, high-capacity beds.

• Stainless steel
• Carbon steel
• Titanium · zirconium
• Special alloys

Applications: desulfurization and decarburization in ammonia plants, decompression in crude-oil separation, methanol and organic-acid separation, absorption/desorption towers

A high-porosity, symmetric ring with continuous, evenly distributed surface. Versus a standard Pall ring, gas flux can rise 15–30% and pressure drop fall 20–30%. The open, non-nesting structure promotes droplet formation and uniform distribution at very low pressure drop — well suited to vacuum and low-pressure service.

Applications: high-efficiency, low-pressure-drop gas–liquid contacting across a wide operating range
