At Ardorvis Technology Ltd, we supply high-performance random packing media for mass transfer, gas-liquid separation, and contaminant scrubbing applications. Our portfolio includes advanced solutions such as Tripack, Pall Rings, Ralu Rings, Ralu-Flow, and the Raschig Super-Ring® Series— proven technologies from industry leaders

Whether upgrading a biogas plant, installing a new scrubbing tower, or optimising a distillation column, we offer full engineering support, supply of OEM and equivalent internals, and media replacement services.

Applications We Serve

• Biogas scrubbing and upgrading (CO₂, H₂S, NH₃)
• Distillation, rectification, and absorption towers
• Odour control and chemical scrubbing
• VOC, solvent, and acid gas treatment
• Cooling tower and degassing applications

Our Packing Media Portfolio

Tripack (Tri-Packs®)

Spherical, free-flowing plastic elements offering excellent wetting and minimal pressure drop.‍

Sizes: 1", 2", 3.5"
Free Volume: Up to 95%
Materials: PP, PE, PVDF, ETFE
Ideal for: Odour control units, low-pressure drop scrubbers‍

Key benefits:

• High fouling resistance
• Excellent gas-liquid dispersion
• No nesting or settling
  
  

Pall Rings

A benchmark cylindrical random packing used across all major mass transfer operations.‍

Materials: Metal (SS, Hastelloy),ceramics, plastics (PP, PVDF)
Sizes: 15–90 mm
Surface Area: Up to 350 m²/m³‍

Key advantages:

• Low pressure drop
• Good liquid distribution
• Widely compatible with legacy systems
  

Ralu Rings

Enhanced Pall Ring geometry with bead reinforcement(metal) or injection-moulded stability (plastic).‍

Surface Area: Up to 320 m²/m³
Free Volume: Up to 98%
Performance: Improved mechanical strength, lower pressure drop, higher mass transfer efficiency
Applications: High-capacity absorption and stripping columns

‍

Ralu-Flow

An advanced plastic packing designed for maximised flow rates, minimal liquid holdup, and exceptional thermal/mechanical stability.‍

Sizes: No. 1, No. 2
Surface Area: 100–165 m²/m³
Free Volume: 95%
Optimised for: NH₃ scrubbing, large-scale CO₂ removal
‍

Benefits over Pall Rings:

• Smaller column diameters
• Lower pressure drop
• Better liquid distribution
  
  

Super-Ring® &Super-Ring® Plus

Fourth-generation metal random packing designed for maximum efficiency, low pressure drop, and superior gas-liquid interaction.‍

Free Volume: 95–98%
Surface Area: Up to 450 m²/m³(size-dependent)‍

Features:

• Waveform geometry for turbulence and efficiency
• Ideal for solvent recovery, ammonia and CO₂ stripping
• Higher loading capacity than 50 mm Pall Rings

Additional Media & Accessories

We also supply and install:

• Liquid distributors, packing retainers, and support plates
• Column internals for new builds and retrofits
• Media reconfiguration and spent media disposal services

‍

Material Options

We offer packing in:

• ‍Metals:Stainless steel 304/316, Monel, Hastelloy, Titanium‍
• Plastics:PP, PE, PVDF, PFA, PTFE, ECTFE, PES, PPS, LCP‍
• Ceramics:High-purity porcelain for high-temperature chemical resistance

We guide clients on material compatibility based on gas composition, temperature, corrosive agents, and pressure requirements.
