        Honeycomb monoliths
         

        [ Products Description ]
        High surface area, large heat capacity, low thermal expansion, resistant to corrosion and high temperature, ceramic honeycomb monoliths have been well used in chemical, metallurgical,  gas and environmental protection industries.
        [ The main usage is as follows ]
        • Tower packings-- With high surface area, even distribution of fluid and, efficient in mixture separation in chemical & petrochemical industries.
        • Catalyst carriers-- Reduce the oxidation temperature of VOC in purification of industrial exhaust gases in RCO systems and automobiles.
        • Regenerative heat step-up transformer-- Large heat capacity, low resistance to fluid and, energy saving up to 40-70% in RTO systems.
        • Gas combustion distributor-- Distribute the heat uniformly, and make the combustion completely. It can save energy more than 10%.
        • Kiln furniture in refractory industries-- Low bulk density and high thermal efficiency.
