RHI Magnesita is transforming refractory management in rotary kilns through its award-winning Lining Evaluation Scan (LES). This high-precision 3D laser solution provides a digital, fast, and nondestructive method for assessing refractory thickness across the entire kiln. In just three hours, LES delivers high-resolution 3D maps with ±2 mm accuracy eliminating manual measurements and significantly reducing risk and downtime.
In 2025, LES presentations received two major industry recognitions. It was voted Best Technology Provider Presentation at the FICEM Latin American Cement Congress in Lima (Peru). It also won Best Presentation at SEMTEC, the leading cement and lime seminar in South America, marking RHI Magnesita’s second consecutive win. At both events it was chosen directly by the live audience. This year’s presentations highlighted LES’s expanded reach beyond rotary kilns, including calciners, coolers, cyclones, and Maerz kilns.
LES is already deployed in over 48 cement plants across Latin America, helping operators move from reactive to predictive maintenance. Thanks to virtual walkthroughs and remote analysis tools, experts can inspect and advise on kiln condition from anywhere in the world. The result: Faster, safer, and smarter refractory strategies—tailored to each zone, each condition, and each campaign. The LES is another solution aligned with our 4PRO refractory solutions contract model—a digital-first strategy that combines performance, partnership, people, and planet. These two awards reflect the recognition and trust of our customers across South America, reinforcing our commitment to innovation that delivers tangible results.
