Segmented Honeycomb for RTOs
Drop-in replacement with enhanced reliability and cost advantage
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.
Same Performance, Better Economics
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.
Thermal Shock Protection
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.
Plugging Resistance
Long monolith channels accumulate particulates progressively. Segmented design creates natural mixing zones at segment interfaces where turbulence disrupts particle accumulation pathways. The shorter individual flow paths reduce the opportunity for channel plugging.
Cost Advantage
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.
