AREACH - Model 13*13 cells -Dense Alumina blocks
Heat absorbing ceramic mass with its great advantage of combination of high heat recovery with low-pressure drop , 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. As a key components of the thermal storage system, applies to recover thermal energy in RTO (Regenerative Thermal Oxidizers) , Volatile Organic Compounds (VOCs) and odorous emissions etc. The packing material was orderly placed into the RTO to form a media bed.1. Material : Dense Alumina
2. Sizes : 100*100*100mm, 100*150*150mm, 150*150*150mm, 150*150*300mm.
