Honeycomb Monolith for RTOs

Parallel Channel Heat Exchange

In an RTO, the ceramic bed alternates between absorbing combustion heat and releasing it to incoming process gas. Honeycomb accomplishes this through straight parallel channels — gas flows through the full bed depth in direct contact with the channel walls, concentrating heat exchange across the entire ceramic mass. The result is predictable thermal energy recovery at low pressure drop for the surface area provided, which is why honeycomb has been a standard RTO heat recovery medium for decades.

Cell Density and the Efficiency Tradeoff

The four available cell densities — 25, 40, 43, and 50 cell — span a meaningful range of thermal performance. Higher cell count means more ceramic surface area per module and higher thermal energy recovery at a given bed depth, but also higher pressure drop and heavier module weight. Lower cell count reduces pressure drop and accommodates higher particulate loading before channel bridging becomes a concern. The right selection depends on your thermal efficiency target, allowable pressure drop, and process gas composition. Lantec's design service specifies the correct cell density and bed configuration at no charge — no upfront commitment required.

Monolith in the Lantec RTO Lineup

Lantec's RTO media line covers the full range of project requirements. For honeycomb-specified projects, both Honeycomb Monolith and Segmented Honeycomb are available — Segmented Honeycomb provides the same fundamental heat transfer geometry with lower cost from a patented manufacturing process and distributes thermal stress across independent segments rather than through the full monolith depth. For projects where media architecture is open, MLM and LanteComb offer layered designs engineered to address the thermal cycling limitations of full-depth monolith. Lantec's engineers can help identify the right media for your project's specification and operating conditions.

Design Service and Performance Warranty

Honeycomb Monolith is supplied with the same free design service and performance warranty available across Lantec's full RTO media line. Lantec's engineers will specify bed depth, cell density, and transition media configuration at no charge. When Lantec designs the system, the performance warranty comes with it.
