Product Detail

Dense Alumina blocks as a reliable heat exchange media, is the key components of the thermal storage system widely used in RTO (Regenerative Thermal Oxidizers) media and maintenance or some alkali applications because of his wear and corrosion protection and energetic performance.




Honeycomb ceramic (Dense Alumina Blocks) provide the most economical combination of pressure drop, thermal efficiency and destruction efficiency.

The regenerative thermal oxidizer (RTO) converts volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) to carbon dioxide and water vapor through thermal oxidation.
