Product Detail

Over the past few decades, several different types of regenerative material ( high material density media) have been used for RTOs. Three main categories are random packing, monolithic structured block and corrugated structure packing.

Dense Alumina blocks also known as heat media as a reliable heat exchange media, is one type of monolith structured blocks as key components of the thermal storage system widely used in RTO (Regenerative Thermal Oxidizers) media and maintenance for his excellent corrosion resistance.
