At its site in Unterschleißheim near Munich, Germany, Linde has implemented a comprehensive digitalization concept for the production and intralogistics of specialty gases. The group-wide competence center is considered a strategically important facility in the international production network. The introduction of automated processes brings clear added value for customers, as supply reliability, traceability, and quality control are significantly improved.
High quality requirements for test and calibration gases
Test and calibration gases are used in analytics, environmental measurement technology, and safety-related applications, among other things. They must have precisely defined compositions and are subject to strict tolerance limits and analysis specifications. The production of these high-precision gas mixtures requires the selection of suitable container materials, complex gravimetric filling, homogenization, and final analytical approval. In addition, all work steps must be fully documented.
Digitally controlled production processes at Linde
An MES (Manufacturing Execution System) developed specifically for these requirements controls the entire process flow. It coordinates and documents all sub-processes, from bottle sorting and laboratory analyses to filling and dispatch preparation. Digital networking eliminates media discontinuities, thereby increasing data consistency and process stability. The system also provides all information centrally for audits or queries regarding batch tracking.
Automation through autonomous conveyor technology and warehouse logistics
In addition to process control, Linde relies on fully automated internal logistics. Autonomously driving industrial trucks transport the gas cylinders between the production and storage areas. The gripping technology of these vehicles was specially designed for cylinder handling at Linde. In the warehouse area, an automated gantry system ensures precise storage and retrieval. This unit operates independently and enables quick access to all stocks.
Linde sets new standards in chemical production
Through the use of automation and digital process control, Linde is realizing highly available, flexible, and scalable specialty gas production. The solution reduces manual intervention, minimizes sources of error, and increases process reliability. At the same time, efficiency is improved through more efficient processes and shorter throughput times. The company is thus demonstrating how digitalization can be implemented sustainably in the chemical industry.
