The multifunctional sanitary expansion vessels with a fixed membrane are designed for dual use. They can be used as expansion vessels in heating systems and as pressure tanks for sanitary cold water systems.

The protective casing with a patented fastening system ensures protection against the corrosion of the inner wall and suitability for contact with household water.

In sanitary installations, the vessel must be connected to the cold water inlet.
