GRIESHABER GMBH, RAVENSBURG SCHMALEGG (GERMANY) NEW CONSTRUCTION OF CLEAN ROOMS IN THE NEW VMC (VESSEL MANAGEMENT CENTER)

The Vorarlberg-based company NETZER GROUP has established itself as a leading specialist for cleanroom technology in the pharmaceutical industry. Globally active pharmaceutical companies value the NETZER GROUP's outstanding expertise, especially when it comes to combining operational efficiency, innovation and cost-effectiveness. As a total and general contractor, the company demonstrates its expertise time and again, particularly through its three business divisions: NETZER TGA for technical planning, NETZER MSR for control and regulation technology and NETZER RRT for customized, ready-to-use cleanrooms. This comprehensive expertise enables the Austrian company to be internationally successful.

The NETZER GROUP recently proved this once again when it successfully implemented the order for two clean rooms with a total area of 600 m² for Grieshaber GmbH at the new VMC (Vessel Management Center) site in Ravensburg Schmalegg. Grieshaber, a German company specializing in pharmaceutical logistics, needed these special rooms to meet the high requirements of the pharmaceutical industry. The clean rooms provide a closed, pressurized production environment whose humidity, temperature and particle count are regularly monitored. Such conditions are required for around 900 cryogenic containers. The containers filled with active ingredient are transported under refrigeration between the various production sites in the pharmaceutical network. After the substance has been emptied, the tanks return to the VMC, where they are cleaned centrally and serviced or repaired if necessary. This means that the vessels can be delivered just-in-time to the respective production site for the next planned use at any time.

Cleaning these cryogenic containers is a critical process that must ensure the highest levels of purity and sterility to prevent contamination. A considerable amount of hot water at 70 degrees is required for the cleaning process, which must be cooled to 35 degrees before being discharged into the waste water channel. Here, the NETZER GROUP was able to impress with an energy-efficient solution: by using a two-stage heat recovery system, Grieshaber uses the waste heat from the cleaning process and thus saves half the energy - a significant benefit both for the environment and for operating costs.

As a total contractor, the NETZER GROUP focused on cost-efficient planning and execution for this project. The clean rooms were implemented as a "hall-in-hall" construction, with all the technology and media piping housed in a platform above the steel structure to create maximum space for maneuvering and storage areas. The implementation took the form of prefabricated, turnkey modules that could be assembled and put into operation immediately after factory acceptance by the customer. Throughout the entire project, Grieshaber had a single point of contact at the NETZER GROUP, which facilitated communication and drove the project forward efficiently.
