Plastic Random Packing

Economical, versatile industry-standard plastic packing. Two rows of punched holes with inward-folded fingers raise throughput, improve efficiency and lower pressure drop versus ceramic packing. Higher liquid hold-up aids absorption with slow reactions, and the ring-and-spoke construction gives high mechanical strength for deep beds in corrosive service.

• Polypropylene (PP) · glass-filled PP
• LDPE · HDPE
• PVC · CPVC
• PVDF (Kynar) · ECTFE (Halar) · ETFE (Tefzel) · PFA

Applications: absorption, scrubbing and stripping — a versatile, corrosion-resistant alternative to metal Pall rings

Saddle-shaped packing with saw-tooth edges in heat- and corrosion-resistant plastics. Low pressure drop, high flux and high efficiency with easy handling — higher capacity and lower pressure drop than ceramic saddles. Relatively high liquid hold-up suits slow reactions, and the self-distributing geometry minimises channeling.

• PE · PP
• PVC · CPVC
• PVDF

Applications: absorption, scrubbing and stripping; pulp-and-paper service such as bleach-plant absorbers — a versatile alternative to ceramic saddles in corrosive duty

Special-purpose random packing in PTFE — one of the most chemically stable materials available, resisting virtually all acids and alkalis and stable across roughly −260 °C to +260 °C. The classic ring geometry gives a predictable, well-characterised bed for the most aggressive media.

• PTFE (Teflon)
• PP · PE · PVC

Applications: extreme chemical-resistance service; distillation and chemical processes handling aggressive media such as HF, fuming acids and strong alkalis

An open-celled random packing, typically injection-moulded in polypropylene, with a spiral configuration that enlarges surface area and void space for better mass transfer. The non-nesting geometry keeps the bed uniformly open — high void ratio, even gas–liquid distribution and low pressure drop.

• Polypropylene (PP) · glass-filled PP
• PVC · PVDF · HDPE

Applications: gas absorption, acid-gas absorption, cooling-tower fill and gas purification

Hollow spherical packing with a large contact area, stable chemistry and long service life. High liquid/vapour loading allows a smaller column diameter, with high efficiency, low pressure drop and wide turndown. The free-floating action under gas/liquid flow provides self-agitation and self-cleaning.

• PP · PE
• PVC · PVDF

Applications: salt-eliminating and coagulation water tanks, water treatment; coal-gas washing, fertiliser hot-gas saturation, naphthalene and ammonia washing towers; heat-exchanger and catalyst support media; tower revamps

High-performance plastic packing with superior efficiency, capacity and pressure-drop characteristics — over 60% higher efficiency and about 20% lower pressure drop than a 3.5″ plastic Pall ring. The multi-arm star geometry maximises surface area and void space in a single symmetrical unit.

• Polypropylene (PP)

Applications: fume scrubbing (acetic acid, ammonia, formaldehyde), acid-gas absorption (HCl, SO₂, H₂S), VOC stripping, wastewater treatment, flue-gas scrubbing

Two hemispheres of staggered fan-shaped leaves forming a ball with far more surface area than an ordinary spherical filler. Light weight, wide free space, low wind resistance and a hydrophilic, well-wetted surface — a good balance of surface area, void fraction and pressure drop across a wide size range.

• PE · PP · RPP
• PVC · CPVC

Applications: sewage treatment, flue-gas desulfurization in power plants, oily-water separation, seawater desalination, purified- and waste-water treatment

A high-performance random packing in corrosion-resistant engineering plastics, designed for the lowest pressure drop in its class. The open saddle-ring form combines a ring’s surface area with a saddle’s self-orienting behaviour for a well-distributed, non-nesting bed.

• PE · PP · RPP
• PVC · CPVC · PVDF

Applications: petroleum refining, chemical engineering, chlor-alkali production, coal-gas processing and environmental protection

A spiral-filament random packing with excellent mass and heat transfer, high corrosion resistance, low pressure drop and light weight. The open filament shape and large void space cut blower power, while multiple branches give uniform liquid distribution without dead spots. Available in types S-O, S, S-II, M, L, L-II and LL.

• PE (polyethylene)
• PP (polypropylene)
• PVC

Applications: gas absorption (SO₂, SO₃, NH₃, CO₂, H₂S, HCl, Cl₂, HF, NOₓ, solvents), gas stripping, cooling towers, deaerators, reactors; H₂SO₄, chlor-alkali, iron & steel, thermal-power FGD, pulp and water/sewage industries
