Segmented Honeycomb Media for RTOs

Lantec’s Segmented Honeycomb™ is an improved drop-in replacement for traditional honeycomb monolith, delivering the same proven performance with enhanced plugging resistance and thermal shock protection in regenerative thermal oxidizers. Our patented segmented design eliminates common honeycomb challenges while enabling more efficient manufacturing—allowing significant savings without performance compromise.

Technical Description

Segmented Honeycomb provides the same fundamental heat transfer geometry as traditional honeycomb while addressing key operational challenges through intelligent design optimization. While conventional monolithic honeycomb can experience particle buildup in long channels and thermal stress concentration, Lantec’s segmented design eliminates these issues by creating shorter flow paths and turbulent mixing zones between segments, reducing the risk of channel plugging.

The segmented design also provides improved thermal shock resistance compared to monolithic structures. Heat transfer performance remains equivalent to conventional honeycomb, with the same pressure drop characteristics and thermal efficiency.

The segmented architecture enables more economical manufacturing compared to traditional monolith extrusion, reducing production costs while maintaining the same high-quality ceramic performance. This manufacturing innovation allows for cost-effective production while providing the proven honeycomb geometry that engineers specify for reliable RTO operation.

Key Benefits

  • Drop-in Replacement – Equivalent heat transfer efficiency and pressure drop characteristics as traditional honeycomb monolith
  • Enhanced Plugging Resistance – Segmented design prevents particle buildup in long channels through natural mixing zones
  • Superior Thermal Shock Protection – Distributed thermal zones reduce stress concentration during temperature cycling
  • Significant Cost Savings – Manufacturing innovation enables more competitive pricing than traditional honeycomb without performance compromise
  • Standard Configurations – Available in all conventional cell densities (25, 30, 40, 43, 50, 60, etc.) to match existing specifications
