​Random Packed Saddle Media

Cell Stone Ultra Low Pressure Saddle Media

Cell Stone's unique patented ULTRA is designed to replace standard 1" or 25mm saddles and mitigate RTO plugging issues. Ultra delivers 
​lowest pressure drop, highest heat recovery. Reduced pressure delivers horsepower savings. 

​​Cell Stone - Heat Recovery Media for RTOs

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.
