Product Detail

Dense Alumina blocks is a higher efficiency, lower pressure drop media. Its high alumina composition and extraordinary surface area is the key components of the thermal storage system widely used in RTO (Regenerative Thermal Oxidizers) media and maintenance.







Dense Alumina blocks is a type of heat exchanger where heat from the hot fluid is stored in a thermal storage medium before it is transferred to the cold fluid. Effective ceramic media enable the RTO to function correctly and a well-functioning system supports continuing operations along with environmental compliance.
