Heating the Wigger Residential Complex in Garmisch-Partenkirchen

  • A reference in the field of Heizen & Systemschutz Deutschland

Already in 2001, GRANDER® Inline Units were installed to revitalize the drinking water in all five buildings of the Wigger residential complex in the German town of Garmisch-Partenkirchen. As the inhabitants’ feedback was so positive, a further unit was installed to also revitalize the complex’s heating system in 2007.

  • A reference in the field of Heizen & Systemschutz Schweiz

GRANDER® made contributions to the following two projects: the ‘Murgtal wood chip heating plant’ project was kicked off in 2011, but after only a few months of operation, contaminations in the plate heat exchanger started causing problems. Chemical, physical, and microbial analyses showed that the contaminations were caused by microbial factors.
