Product Description

Metal Wire Gauze Structured Packing
Metal Wire Gauze Structured Packing is the premier high-efficiency regular packing for demanding fine chemical separation processes. It is constructed from multiple layers of fine woven wire gauze, crimped into a corrugated form and assembled into tightly packed blocks, with adjacent sheets having opposing corrugation angles. The capillary action of the wire mesh creates an exceptionally uniform, highly active liquid film over the entire surface, delivering the highest theoretical plate counts per meter of any industrial packing. This makes it the definitive choice for vacuum distillation of heat-sensitive materials, isomer separation, and high-purity fine chemical production.
Product Highlights
Ultra-High Separation Efficiency

Delivers theoretical plates up to 10 per meter (BX type) and 20 per meter (CY type), significantly outperforming standard structured packings in difficult separations.

Superior Capillary Liquid Distribution

The fine wire mesh generates strong capillary forces that spread liquid evenly across the entire surface, completely eliminating dry spots and channeling.

Extremely Low Pressure Drop

Vacuum-friendly design with minimal gas-phase resistance, allowing operation at very low column pressures to protect heat-sensitive products.

Minimum Liquid Holdup

Low liquid hold-up volume reduces product degradation time and enables rapid process stabilization, ideal for small-scale batch distillation.

Excellent Corrosion Resistance

Available in 304/316L stainless steel, Hastelloy, Monel, and other alloys to withstand aggressive chemicals and process fluids.

Precise Custom Fabrication

Blocks are accurately cut and assembled to precise diameters, with tight wall-wiping seals that prevent bypassing and maintain peak column performance.

Product Overview & Applications
Frequently Asked Questions
Q What makes wire gauze structured packing superior to sheet metal packing?
The fine woven wire mesh structure creates intense capillary force. This natural action pulls and spreads liquid into a thin, unbroken film across the packing surface, ensuring complete surface wetting even at very low liquid loads, which significantly improves separation efficiency.
Q Why is metal wire gauze packing ideal for vacuum distillation?
Due to its open corrugated arrangement and thin-wire structure, this packing provides minimal resistance to rising gas streams. The resulting ultra-low pressure drop per theoretical stage prevents thermal degradation of heat-sensitive chemical compounds under deep vacuum.
Q What is the difference between BX500 and CY700 types?
BX500 features a specific surface area of 500 m²/m³ and delivers 5 to 8 theoretical plates per meter, offering a balanced combination of high throughput and efficiency. CY700 offers 700 m²/m³ and up to 12 theoretical plates per meter, specifically optimized for difficult separations like close-boiling isomers.
Q How does low liquid holdup benefit batch operations?
A low liquid holdup volume ensures that less material stays inside the tower during runs. This shortens operating transition periods, minimizes the risk of thermal compound decay, and simplifies rapid cleaning during product switches.
Q What alloys are available for highly corrosive process streams?
Standard fabrications are produced using AISI 304 and 316L stainless steels. For aggressive, acidic, or demanding chemical media, packing can be custom woven and assembled using special corrosion-resistant alloys like Hastelloy, Monel, and Titanium.
