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.  

Exceeding Industry Standards 

Cell-Stone® provides acid proof and alkali resistant Regenerative Thermal Oxidizers (RTO) media for VOC destruction devices for new and after market devices.

The engineers of Cell-Stone® have been manufacturing heat recovery media since 1995. As engineers, we are the only heat recovery media manufacturers/suppliers that have designed and built an impressive 400+ RTO units globally, in a 40 year time span.
