ecoline water
Drinking water is our most important food. The quality of drinking water must be of such a high standard that it can be enjoyed without restriction throughout life. For this reason, ever stricter requirements are being imposed worldwide on materials that come into contact with drinking water. The appropriate selection of materials and products for drinking water installations is therefore extremely important. Technical, economic, but especially hygienic and health aspects play a major role.
Copper alloys have proven themselves technically and hygienically billions of times worldwide in drinking water installations and will therefore continue to be the basis for clean drinking water in the future.
Here you will find detailed information on ecoline water – please contact us if you have any questions.
All current Guidelines for lead-free materials are summarised in the Regulations.
