            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.
