MESH PADS
Galiakotwala Engineering has supplied advanced Mist Eliminator systems manufactured from speciality materials to 216+ Chemical Plants in 41+ countries across the world.
Mesh Pads are knitted mesh blankets made from metal or plastic wire, designed for the efficient and cost-effective removal of entrained liquid droplets from gas streams. Galiakotwala Engineering designs and fabricates mesh pads in any required size for installation in new or existing process vessels. Typically, they are installed so that gas flows upward through the pad.
How It Works
Vapor and entrained liquid droplets enter mesh blankets positioned between support grids. Vapor passes through easily, while droplets—due to their inertia—collide with the wire surfaces. The droplets coalesce, grow in size, and flow downward along the mesh. They collect at the bottom and fall into the unit, leaving the vapor stream nearly free of moisture.

Material of Construction
Galiakotwala Engineering manufactures Mesh Pads from a wide range of conventional and specialty materials, including:
- Stainless Steel (316 L, 304 L, and more)
- Polypropylene and other Polyolefins
- PTFE, ETFE and other Homopolymers
- Alloy 20 and other speciality Alloy
- CorFre (SX) (most preferred material for Sulphuric Acid applications)
- CorFre A6
We can also manufacture mesh pads based on customer-specified materials for special applications.
Collection Efficiency and Pressure Drop
- Mesh Pads exhibit good collection efficiencies in the range of 2 to 30 microns.
- Pressure drop ranges from 5 mm WC to 100 mm WC, depending on the design of the Mesh Pads.
Specialty Mesh Pads
Corrosion-Resisitant Type Mesh Pad
- Made from CorFre® A6, a high-performance alloy designed to withstand a wide range of corrosive liquids.
- Offers long service life in any environment with no shrinkage issues.
Low Corrosion CorFre® (SX) Type Mesh Pad
- CorFre® (SX) is an alloy specifically developed for use with concentrated Sulphuric Acid.
- Over 50 Sulphuric Acid Plants have upgraded to this Mesh Pad, making it a preferred material of choice.
- Delivers long life in Sulphuric Acid applications with zero shrinkage problems.
High Efficiency
Type Mesh Pad
- Achieves 99% efficiency in capturing particles as small as 2 microns.
- Combines the advantages of both Candle Filters and Mesh Pads for superior performance.
What Our Customers Say
“I am pleased to report that since installing the GEC BMW Type Candle Filter in our Interpass Absorption Tower (IPAT) at our Sulphuric Acid Plant in 2019, it has performed exceptionally well. We have not observed any acid condensate at the outlet of the IPAT, indicating the filter is effectively removing any impurities.”

“We were facing mist carryover problems in the Drying Tower for a long time. We discussed the problem with the Galiakotwala Technical Services (GTS) Technical team.They studied the issue and gave the solution of an advanced Demister Pad of SX Wire Mesh for Drying Tower and solved this prolonged problem permanently.”
General Manager (Auxiliary),
Century Rayon
“Galiakotwala Engineering Company has provided us with the best solution in form of Alloy Piping to get rid of continued issues of leakage in conventional Sulphuric Acid Piping. After installation of the Alloy Piping, we observed zero leakage and significant cost savings due to reduced downtime. Since then we have changed most of our Acid Piping in both Sulphuric Acid Plants at Haldia with their low corrosion alloy.”
General Manager (Engineering),
Tata Chemicals Limited, Haldia
“We wanted to replace our old Brick-Lined Acid Towers with a newer technology due to difficulty in location and repair of leaks in these Acid Towers. GEC gave a solution of an complete Alloy Tower 7500 mm in diameter including all internals such as Distributor, Mist Eliminators, Packing and Support, etc. We are happy to note we have observed no corrosion in last 7 years and achieved 99.99% absorption efficiency.”
JSC Apatit,
Russia
“We were continuously facing excess mist generation and moisture carryover problems in FAT and DT with the conventional distributors. Galiakotwala Engineering Company (GEC) replaced conventional distributors with Alloy Distributors in 2004. Since then, there is no change in the thickness and deformation of hole sizes of the branch pipes of the distributor. We appreciate the quality of work and and the materials used by GEC even after 18 years of operation.”
Deputy General Manager (Mechanical),
Paradeep Phosphates Limited
“We are using your Vane Separators for the last 15 years and have never faced any issues in the performance or life of the equipment. We are thankful to the Galiakotwala team for designing the special type Vane Separators according to our requirement that continues to ensure our process operates.”
Sr. Manager (Mechanical),
TATA Steel
“In 1987, Galiakotwala Engineering Company (GEC) provided our first Shell and Tube Type Heat Etxchanger with the assurance of an advanced, efficient design and manufactured with a low-corrosion alloy that would extend its lifespan. Even after 30+ years of trouble-free operation, the Heat Exchangers are still functioning effectively. We are pleased to report that GEC adhered to their commitments.”
