Sonnenalp Hotel - European Health & Spa Award

The Resort Sonnenalp pleases its guests with a combination of luxury, familiar charm and GRANDER water.  The installation of the device invented by Tyrolian Johann Grander brought about an unusual result at the beginning:  “The staff complained that the glasses were streaky,” Georg Stoss, the technical manager of Sonnenalp explains.  “Obviously the conductance of the water changed due to the GRANDER technology, too much dishwashing detergent was used, and thus the streaks.  We reduced the amount of cleaning detergent by 10 percent and the glasses were clean again.” 

The effect was particularly pleasant in the swimming pool area.  Georg Stoss says, “We used 10 bottles fewer of chlorine gas, which adds up to 650 kilos.  This is not only positive for the environment, but also for one’s sense of smell.  In our swimming pool it hardly smells of chlorine any more, and this is, of course, a pleasant aspect for our guests!”
