Large-Diameter Sintered Metal Sparger Ring for Industrial Reactor Gas Distribution and Aeration

Sintered Metal Sparger Rings

CMI Sintered Metal Sparger Rings are high-performance gas distribution solutions specifically engineered for industrial-scale reactors and large-diameter vessels. These assemblies consist of precision-welded, arc-shaped sintered porous tubes that deliver a uniform, 360-degree curtain of micro-bubbles. This circular configuration ensures comprehensive aeration coverage across areas up to 12 m², effectively eliminating “dead zones” and maximizing gas-liquid mass transfer efficiency.

Designed for heavy-duty environments, CMI Sparger Rings achieve an oxygen utilization ratio of 30% to 40%. They are available in standard diameters from 1800 mm to 2500 mm, with full customization options for even larger vessels. Manufactured from premium alloys such as 316L Stainless Steel, Pure Titanium, and Hastelloy, these rings maintain structural integrity in high-temperature and highly corrosive processes. The rigid, abrasion-resistant sintered matrix ensures zero media migration, making them ideal for high-purity applications in petrochemical refining, large-scale water sterilization, and pharmaceutical fermentation.

Engineered for Challenging Industrial Processes

  • Large-Scale Sterilization: Ozone aeration for high-volume pure water and mineral water reservoirs.
  • Advanced Wastewater Treatment: Deep-tank aeration for domestic sewage and aggressive industrial effluent.
  • Petrochemical & Refining: Degreasing aeration for oil-produced water and processing high-viscosity fluids in volatile environments.
  • High-Temperature Reactors: Reliable gas injection in extreme thermal conditions where polymer materials degrade.
  • Anti-Scaling Applications: Sintered metal surfaces resist scaling, ideal for hard water or mineral-rich process fluids.

Why CMI Sparger Rings?

  • Modular Arc-Shaped Design: Arc-welding technology ensures structural integrity across large diameters without compromising the porous matrix.
  • Uniform Gas Distribution: Consistent micron rating prevents pressure drops and ensures even bubble release across the entire aeration area.
  • Zero Media Migration: Rigid sintered structure prevents metallic particle contamination.
  • Easy Maintenance: Compatible with chemical cleaning and back-flushing, extending service life in "easy-scaling" environments.
