Under the guidance of the Shanghai Research Institute of Chemical Industry, our company specializes in manufacturing new-type, high-efficiency structured corrugated packing and random packing.
To meet diverse corrosive and thermal requirements, our column internals can be precision-manufactured using:
Stainless Steel (SUS304, SUS316L, etc.)
Copper & Aluminum
Pure Titanium & Molybdenum-Titanium Alloy
Our tower packing products are widely deployed globally in high-stakes fields, including:
Fine Chemicals & Petrochemicals
Flavors & Spices Extraction
Pesticides Production
Structured Packing: Mesh, wire mesh, orifice plate, and expanded orifice plate types.
Random Packing: Metal Pall rings, metal cascade mini rings, and metal Intalox saddle packing.
Our premium metal structured packing is widely compatible with chemical and [distillation columns] to enhance mass transfer efficiency.
