Cell-Stone® engineers work with your engineering team in optimizing the plant's overall RTO performance.  With decades of Regenerative Thermal Oxidizer (RTO) experience, we specialize in air pollution control solutions for these unique core industry sectors:

  • Wood and Lumber
  • Printing
  • Wastewater

​​Extruded monolith is an alternative to random packed media. Cell-Stone® offers these cells-per-inch choices:

  • 25 x 25 CPI
  • 43 x 43 CPI

Heat Recovery Media

Our random packed and monolith media meets or exceeds ASTM standards
with regard to chemical composition and crushing strength. 
​Cell-Stone's® random packed media is guaranteed for 2 years against thermal decomposition.

Our random packed media is press manufactured.  Unlike inferior extruded media,
each individual saddle is pressed for identical size, shape and weight;
​made with superior quality and delivers 25% more crushing strength.
