Field-proven deployments of silicon carbide honeycomb structures solving critical heat transfer and aggressive fluid separation challenges worldwide.
Standard cordierite honeycombs fail rapidly when halogenated solvents, organosilicons, or sulfur vapors enter the thermal oxidizer stream. SiC honeycombs withstand aggressive acidic condensates, delivering a 95%+ thermal recovery factor without bed glazing, cracking, or thermal degradation.
Operating stably above 1200°C in reducing hydrogen environments, SiC honeycomb filter arrays remove sub-micron particulate matter, fly ash, and tar residues before catalytic conversion stages, preserving downstream catalyst beds from particulate contamination.
Silicon carbide honeycombs operate as structural microchannel thermal storage cores in advanced solar receivers and ultra-high-temperature fluid heat exchangers. Superior thermal conductivity prevents local hotspots and thermal shock failure during cyclical heat transfer surges.
