The corrugated geometry provides large specific surface area (125–750 m²/m³) and promotes uniform liquid film formation, delivering theoretical plates of 1.0–8.0 per meter.
The open-channel structure with optimized corrugation angle minimizes gas flow resistance, significantly reducing energy consumption and operating costs.
Large void fraction and excellent hydraulic performance enable higher gas and liquid loads compared to random packings.
Perforated and embossed surface texture improves liquid spreading and wetting, preventing channeling and dry spots.
Available in 304/316L stainless steel, titanium, and other alloys to withstand aggressive chemicals and high temperatures.
Blocks can be precision-cut to fit any tower diameter, with custom corrugation angles and sheet thicknesses available.

Metal structured packing is engineered for mass transfer processes such as distillation, absorption, and stripping towers across the chemical, petrochemical, and refining industries where high separation efficiency and minimal pressure drop are required.
Unlike random packing dumped loosely into a tower, structured packing consists of corrugated metal sheets arranged in regular patterns. This organized geometry ensures uniform liquid flow, higher void fractions, significantly lower pressure drops, and superior separation capacity.
Standard options include Stainless Steel 304 and 316L. Other alloys such as Titanium, Hastelloy, and carbon steel can also be supplied depending on the corrosive nature and temperature profile of the operating environment.
The number indicates specific surface area (m²/m³). Lower numbers like 125Y and 250Y provide higher hydraulic capacity and ultra-low pressure drop, ideal for vacuum distillation. Higher numbers like 500Y and 750Y offer maximum separation stages (theoretical plates) for high-purity separation tasks.
Yes, packing blocks are precision-fabricated and segment-cut to match any column inner diameter, manway access dimensions, and internal configurations, making them ideal for both new installations and column revamps.
Perforations and embossing enhance surface tension and wetting characteristics, allowing the process liquid to spread evenly into a continuous thin film, which maximizes gas-liquid contact and prevents dry channeling.
