Product: Ceramic Raschig Rings
Ceramic Raschig Rings are the foundational random tower packing used globally in chemical processing, gas scrubbing, distillation, and absorption columns. Manufactured from high-purity, inert alumina-silicate ceramics, these simple cylindrical rings deliver exceptional corrosion resistance, thermal stability (up to 1000°C/1832°F), and mechanical strength in aggressive environments where metal or plastic packings fail.
Unlike advanced packings (e.g., Pall Rings), Raschig Rings feature a solid-wall cylindrical design with uniform wall thickness and an internal diameter typically equal to their wall thickness. This straightforward structure offers:
1.Ultimate Chemical Inertness - Resists virtually all acids, alkalis, solvents, and oxidizing agents.
2.Thermal Shock Resistance - Withstands rapid temperature changes in quench towers or cooling processes.
3.High Crushing Strength - Maintains structural integrity under heavy bed loads.
4.Cost-Effectiveness - Economical solution for large-volume towers or highly corrosive duties.
While less efficient than modern packings, their robustness makes them ideal for acid regeneration, drying, sulfuric acid plants, and wastewater scrubbing where fouling or extreme conditions prioritize durability over theoretical efficiency.

* Pros:
Zero corrosion risk in pH 0-14 environments
Sintered ceramic surface minimizes fouling
1.5x higher crush strength vs. ceramic saddles ring
Lowest cost per m³ among ceramic packings
* Limitations:
Higher pressure drop than Pall Rings/Berls Saddles
Lower mass transfer efficiency (requires taller beds)
Potential for nesting (stacking), reducing surface area
