Since last Friday (29 April), the cooling supply to Giessen University Hospital has been secured again. The district heating department of Stadtwerke Gießen AG (SWG) not only supplies customers with heat - SWG also operates a seven-kilometre-long cooling network. The cooling network supplies the Giessen University Hospital and the university's properties with cold water for air conditioning and cooling medical equipment. Urgent repair work had to be carried out on the almost 30-year-old cooling network. In itself, this repair work is nothing special for Stadtwerke. However, this work had to ensure an emergency supply of cooling for the hospital and the university: This was both a technical and logistical challenge. SWG set up six mobile cooling units to continue supplying the customers with cooling. Together with the specialist staff at the hospital and the university, the SWG experts organised an emergency supply for the most important consumers. This was because the mobile cooling units were unable to cover the university hospital's entire cooling requirements. Stadtwerke not only renewed parts of the pipe network, but also optimised the cooling supply at the same time. SWG joined the existing pipework with the pipework network - which runs parallel to the hospital's pipework but ends at the natural sciences centre on Heinrich-Buff-Ring. This allows the municipal utilities to switch over to the other pipeline in the event of a leak in one of the pipelines. The actual repair work could be carried out as planned and the normal supply was restored in time for the weekend.
