Metal Structured Packing Manufacturer | 500Y/700Y Metal Packing

Manufacturer Brief: FXSINO is a metal structured packing manufacturer supplying 500Y and 700Y models in SS304, 304L, 316, and 316L. These high-specific-surface-area packings are engineered for vacuum distillation, thermal-sensitive separation, and precision rectification where low pressure drop and high theoretical plate count are critical .

Core Performance Advantages

• Ultra-High Separation Efficiency: 700Y delivers 8–10 theoretical plates per meter — ideal for isotope separation and high-purity fine chemicals .
• Low Pressure Drop: 500Y operates at just 0.05–0.3 kPa/m, enabling deep vacuum distillation below 7 kPa without excessive energy loss .
• Capillary Wettability: Wire gauze construction traps liquid into a thin film, maintaining high efficiency even at spray densities as low as 0.2 m³/(m²·h) .
• No Amplification Effect: Regular geometric arrangement means lab performance scales predictably to large-diameter towers .
• Large Operational Flexibility: Performs consistently across wide load fluctuations with almost no low-load limit .

• • Vacuum Distillation: Thermally sensitive materials, deep vacuum service below 7 kPa — essential for fragrances, vitamins, and fine chemicals .
• • Precision Rectification: High-purity solvent recovery (≥ 99.9%), isomer separation, isotopic compound separation .
• • Petrochemical: Ethylene demethanizer (cryogenic separation), styrene monomer purification, refinery vacuum towers .
• • Coal Chemical: Methanol rectification (3-column / 4-column process), glycol separation .
• • Pharmaceutical: Vitamin E refinement, vitamin C extraction, API purification .
• • Air Separation: Liquid nitrogen wash, cooling tower, rare gas recovery .

• Layer Orientation: Adjacent packing beds must be rotated 90° relative to each other to promote radial mixing and prevent channeling .
• Pour Height: Always pour packing from a height above the bed — never drop directly. Personnel must not stand on the packing; lay boards to distribute weight .
• Bed Limiters: Install hold-down plates above each bed to prevent fluidization under high gas velocity. See our Bed Limiter guide.
• Redistribution: For beds taller than 3–5 m, install liquid collectors and redistributors. See our Collector & Redistributor guide.
• Not Recommended For: Heavy fouling services and strongly corrosive media — consider perforated plate type instead of wire gauze .

Q: When should I specify 700Y instead of 500Y?

A: Choose 700Y when your separation requires 8–10 theoretical plates per meter — typically isotope separation, isomer separation, or ultra-high-purity fine chemicals. For general vacuum distillation of thermally sensitive materials, 500Y offers the best balance of efficiency and capacity .

Q: What is the minimum column diameter for 500Y/700Y?

A: Wire gauze structured packing performs best in small-to-medium diameter columns (typically DN100–DN1200). For larger diameters, perforated plate type (250Y/350Y) is recommended to manage manufacturing and installation costs. We engineer each packing disc to your tower's exact inner diameter .

Q: Can you manufacture to our tower drawings?

A: Yes. As a structured packing manufacturer, we fabricate every disc to your column's inner diameter, bed height, and material specification. Send us your tower drawing and process conditions, and we will deliver ready-to-install packing discs with full dimensional inspection reports .
