Reflex for heating, solar power and cooling water systems

Reflex diaphragm expansion vessels are available in different pressure ranges and nominal volumes, either flat or cylindrical, depending on the application, and with a fixed diaphragm or replaceable bladder.

Reflex N

Reflex N are the world's most frequently used small vessels. The fixed diaphragm has proved itself millions of times over and has shown itself to be extremely wear-resistant, thanks to its evenly-balanced loading.
