Description
The Ceramic Mini Lessing Ring is an advanced version of the traditional ceramic Raschig ring. It features a design that significantly improves both surface area and compressive strength when compared to the standard Raschig ring. These rings offer exceptional resistance to acids and high temperatures, making them highly versatile for a wide range of industrial applications.
Thanks to their robust structure, Ceramic Mini Lessing Rings resist corrosion from a variety of inorganic acids, organic acids, and solvents (except hydrofluoric acid). Additionally, they can perform reliably under extreme temperature conditions, whether high or low. This makes them an ideal choice for use in industries such as chemicals, metallurgy, coal gas, and oxygen production. These rings are commonly used in drying columns, absorption towers, cooling towers, and scrubbing towers.
Produced through a rigorous calcination process lasting 24 hours, with a sintering temperature exceeding 1000ºC, Ceramic Mini Lessing Rings are inert, ensuring long-lasting performance in demanding environments.
