City hall depot closed on November 5th due to refrigeration machine renovation!
On November 5, 2025, the depot in Wuppertal between the parts of the town hall building will be closed for around six hours from 7 a.m. What is behind this measure? The focus is on necessary work on the refrigeration machine, which dates back to the 1980s and was recently discovered to be defective and irreparable. The parking area is cordoned off early in the morning to make room for a crane and a truck, which will be positioned in the middle area.
The maintenance is part of an extensive renovation of the cooling system, which is carried out in accordance with the strict requirements of DIN EN 378. This standard, which regulates the construction and operation of refrigeration machines, aims to protect the environment, people and system components. In this context, an area for the disposal of pollutants will also be temporarily closed to ensure the safety of everyone involved. Preparations for the work in the attic are already underway, with the cooling pipes needing to be replaced.
The importance of DIN EN 378
DIN EN 378 is an important guideline that is of great relevance not only for operators of refrigeration systems, but also for system manufacturers. It consists of four parts covering basic requirements, construction and operation, and safety precautions. In recent years, the standard has been updated several times to reflect the latest technological developments and increase safety standards.
- Teil 1: Grundlegende Anforderungen und Klassifikationen.
- Teil 2: Anforderungen an Konstruktion und Dokumentation.
- Teil 3: Sicherheitsvorkehrungen für Aufstellungsorte.
- Teil 4: Betrieb, Instandhaltung und Rückgewinnung von Kältemitteln.
The updates in particular address new safety precautions and provide clear guidelines for dealing with flammable refrigerants. This is intended to significantly increase the safety in the operation of refrigeration systems, which is urgently needed in view of the upcoming work in the town hall.
Overall, the closure of the depot represents an important step in ensuring the long-term safety and efficiency of the cooling systems in Wuppertal. The city is trying to keep the inconvenience as low as possible during this time and asks all citizens for their understanding of the necessary work.
