AREACH - Model 50*50 Cells -Dense Alumina Blocks
Over the past few decades, several different types of heat transfer media (ceramic package) have been used for RTOs. Three main categories are random packing, monolithic structured block and corrugated structure packing. Ceramic blocks ( regenerative material) are widely used in the RTO projects, which is one of the air pollution control system, RTOs are always used in industries of pharmaceutical, chemical, electric manufacturing, automobile and machinery manufacturing, metallurgical ,and others who needs to dispose exhaust gas. By the advantages of corrosion resistance and reducing the exhaust emission of thermal equipment, alleviating the air pollution and improve the environment, they are typically used in RTOs.Most popular related searches
