Product Detail

Dense Alumina is a heat absorbing ceramic mass.

It is characterized by a high degree of stability and a very high degree of heat resistance at the same time. Also it is prior to other materials for its water absorption which makes it a perfect option to applied in RTO products applies to recover thermal energy in RTO (Regenerative Thermal Oxidizers) , Volatile Organic Compounds (VOCs) and odorous emissions etc.







The combination of high heat recovery with low-pressure drop.
