Energie Münchwilen AG, 9542 Münchwilen, CH

  • 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.

Umberto Saxer, Aadorf, CH

  • A reference in the field of Heizen & Systemschutz Schweiz
The installation of a GRANDER® Circulation Unit has paid off for Umberto Saxer in Aadorf: heating costs have been reduced by up to 30%. As no more silt or rust forms in the heating pipes, the water stays clean and odorless.
