K P Zimmermann Dairy Production hardwater descaler
K & P Zimmermann Cheese Dairy Production

One month after the installation of Vulcan S25, we made a test with a rusty nail. After two weeks the nail was clean. For us Vulcan is the easy solution against scale and rust and keeps our piping system and appliances clean. We need less maintenance and save money with it.

The visible scale deposits are less and the cleaning is much easier than without Vulcan – with less need of chemicals. Also the scale deposits of the cisterns and shower heads are much less, so we have less maintenance costs. We recommend your Vulcan system and we will install more Vulcan systems in further of our sanitary stations in Switzerland.
