33 July 2019 32 Charleston LaZer made, the high-tech, residue-free welding method The fact that Zehnder Charleston has become a radiator classic is not surprising due to its impressive innovation. Even today it boasts a unique new feature: the manufacturing of Zehnder Charleston with LaZer made. This innovative laser welding method for the production of sectional radiators is setting new standards for quality and technology in terms of precision, quality and functionality. Thanks to LaZer made, manufacturing can be more precise than ever before – all without residues inside the radiator or offsets on its surfaces. This makes for an even more attractive appearance and optimised radiator operation. For more benefits, see the information on the right. Smooth operation, less hassle The application of this new laser welding method ensures completely clean welding. It guarantees that absolutely no residues remain inside the radiator – this prevents the valves and heat generators from potentially becoming blocked. For you, this means reliable operation and less time required to flush out the heating system. Top quality, enhanced appearance Continuous inspection by a 3D co-ordinate measuring machine prevents even the smallest dimensional nonconformities. To ensure absolute tightness, each unfinished structure is subjected to testing in a test bath both during the production process and in the final stage of manufacturing. The unique production method enables leakproof radiators and clean contours free of offsets. The resulting smooth surfaces are easier to clean. Sustainable manufacturing, made in Germany Improved energy efficiency, environmental friendliness and sustainability. Because the new laser welding technology requires less energy than the previous method, Zehnder Charleston boasts a satisfyingly low CO2 footprint. With the “made in Germany” manufacturing label, Zehnder is dedicated to its production site in Lahr as well as to short transportation distances and ensured sustainability. More efficient processes, even faster and more reliable delivery Tube machining is performed directly on the automatically delivered tube bundles. This removes the need for any interruptions between the production stages and speeds up the manufacturing process. Your radiators are therefore delivered to your project site even faster and are guaranteed to arrive on the agreed date.
