Ceramic Berl Ring
Products introduction:
Ceramic Berl Ring is improved from the ceramic Intalox saddle,Ceramic Berl Ring changes the both arched surface can improve the surface area and voidage, Ceramic Berl Ring makes porosity distributed even and improves the distribution of the fluid, greater capacity and lower pressure drop than ceramic rasching ring.
Ceramic Berl Ring with excellent acid resistance and heat resistance. They can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature conditions. Consequently their application ranges are very wide.Ceramic Berl Ring can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc. Ceramic Berl Ring are used in two main fields but have different properties depending on the application. One field is the chemical and petrochemical industries and another is in environmental areas such as RTO equipment.
