The classic Zehnder Charleston radiator with new welding technology

Thanks to the development of production technologies, Zehnder has come up with an innovative laser welding method for radiators. This new technology is applied in the production of large volumes at the German manufacturing site at Lahr, and the innovative RBS welding method will be used for the first time on all the models of the classic Zehnder Charleston.

Unlike regular welding, the new technology is a clean process, eliminating the presence of residue while permitting greater precision for a higher level of quality.

Another innovation is an automated procedure for leakage trials. In the past periodic tests were conducted after the welding of the sections, while the production process was still in progress, followed by a final leakage test. Today the testing can be done in advance for the laser-welded parts.

The new procedures speed up the production process, eliminating interruptions in the various phases.
