LanteComb® Interconnected Cell Media

Higher thermal efficiency at lower pressure drop

LanteComb's patented comb-shaped wall geometry creates interconnected cells that allow gas to move laterally between channels — not just straight through. This unrestricted flow path delivers 3–8% higher thermal efficiency than conventional honeycomb at lower pressure drop, translating to $70,000–$160,000 in annual fuel savings on a typical 20,000 SCFM RTO.

LanteComb® Interconnected Cell Media

The Interconnected Cell Difference

Conventional honeycomb monolith confines gas to closed vertical cells. Each molecule enters a channel and travels straight up, never interacting with adjacent cells. This simplicity limits thermal efficiency — there's no path for the gas to find optimal contact with the ceramic.

LanteComb changes the geometry. The comb-shaped wall structure creates openings between cells, allowing gas to flow laterally as well as vertically. The gas finds its own optimal path through the media, increasing contact time and heat transfer without additional pressure drop. The result is higher thermal efficiency recovery (TER) with the same or lower resistance to flow.

Quantified Performance

On retrofit installations replacing conventional honeycomb, LanteComb delivers:

  • 3–8% TER improvement — Measured improvement in thermal efficiency recovery
  • $70,000–$160,000 annual fuel savings — For a 20,000 SCFM RTO operating 24/7 at $6.90/MMBTU
  • Lower pressure drop — Consistently lower ΔP than 40-cell honeycomb at equivalent bed depth

Media cost for the same-scale RTO: $50,000–$150,000. Payback is measured in months, not years.

Building on MLM's Foundation

LanteComb extends the engineering principles that made MLM the most-installed RTO heat recovery media worldwide. Where MLM solved the thermal cycling problem with layered construction and horizontal gaps, LanteComb adds lateral gas movement within each layer. The result is another step forward on the thermal efficiency curve without sacrificing the reliability that made structured ceramic the standard for RTO applications.

Key Benefits
