Filling group thermaliQ:SB13

The easiest handling with maximum safety!

The filling group thermaliQ:SB13 is designed to secure the drinking water as per DIN EN 1717. The directly installed system separator BA ensures this safety. It prevents the possibly polluted water from flowing back from the heating system. A pressure reducer with integrated pressure gauge allows the variable adjustment of the filling pressure. Shut-off valves on the inlet and outlet side ensure safety on all sides. Thanks to the system separator unit already installed, which can be rotated by 360°, handling is easier than ever before. The filling group can be mounted in any installation situation – both horizontal as well as vertical. Furthermore, the filling group comes completely pre-assembled. This not only makes handling easier, but also saves you considerable time during installation. A dirt strainer on the inlet side complements the thermaliQ:SB13.
