In order to safeguard the existing drinking water quality, HANSA only works with high-grade, durable materials. These include, e.g., plastics with German KTW certification for drinking water, the Water Safe Hitec functional core as well as the dezincification and corrosion-resistant brass alloy MS 63 for all water-bearing parts. The comprehensive HANSA PROTEC system, in particular, plays a valuable role in safeguarding water quality: All brass parts which come into contact with drinking water have a lead content of less than 0.3% and do not have a nickel coating. This means that HANSA products are well below statutory limits. Offering you pure relaxation and enjoyment.
