About our Honeycombs/Filters

At Anderman & Company, we supply a wide range of advanced ceramic filter and honeycomb solutions, designed to deliver reliable filtration, heat recovery, and process stability under extreme operating conditions.

From reticulated foam ceramic filters for molten metal filtration to structured honeycomb ceramics for regenerative thermal processes, our products provide exceptional durability, precision, and efficiency in industrial and high-temperature environments.

Technical Note

Each honeycomb regenerator bed is carefully engineered for demanding RTO conditions, combining materials optimised for heat recovery, chemical stability and structural durability. Compared with random packing (e.g. saddles or plates), structured honeycomb ceramics deliver maximum heat recovery with lower operating costs and superior reliability.

Typical Applications

  • Investment casting and foundry filtration
  • Iron, steel and aluminium production
  • Low-pressure die casting
  • Gas and liquid filtration systems
  • Regenerative thermal oxidation (RTO) and VOC abatement
  • Process gas regenerators and heat recovery units
  • Renewable energy storage and RHV systems

For custom sizes, special dimensions, or unique features, please contact our team for a tailored solution.

FAQs

Your questions answered

What are foam ceramic filters used for?

They control molten metal flow, improve casting quality and remove impurities during filtration — used widely in foundries, iron, steel, aluminium production and low-pressure die casting.

How do honeycomb ceramics improve RTO performance?

Structured honeycomb beds deliver maximum heat recovery with lower operating costs than random packings (saddles, plates) — providing superior reliability and stable performance in regenerative thermal oxidisers and VOC abatement.

What temperatures can they withstand?

Engineered for use above 1600°C with excellent resistance to thermal shock, oxidation and corrosion — exact maximum service temperature depends on the material specified.
