In the modern industrial scenario, technological evolution and component customisation are key factors for companies seeking to maintain and improve their competitiveness, especially in highly specialised sectors such as the chemical-pharmaceutical industry. The rotary joint plays a key role in fluid handling, especially in applications requiring high temperature thresholds and heavy-duty continuous operation. The ability to develop tailor-made solutions that precisely meet customers' needs not only improves efficiency and process reliability, but also translates into a substantial competitive advantage. An emblematic example of this dynamic is the project carried out by Johnson-Fluiten for the development of the latest Custom RHB rotary joint, intended for a specific application in the chemical sector.
