Segmented Honeycomb for Regenerative Thermal Oxidizers (RTOs)
Improved drop-in replacement with enhanced performance and reliability
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.
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.
