Thermostatic domestic hot water mixer for central hot water temperature regulation

The thermostatic domestic hot water mixer tubra®-therm is used wherever a fixed mixed water temperature is desired. tubra®-therm is installed in the system after the water heater and is used to centrally limit the temperature of the hot potable water.

The automatic function of the tubra®-therm is ensured by a highly sensitive thermostatic control element. The control element is surrounded by mixed water and regulates the hot and cold water inflow.

The domestic hot water mixer is insensitive to pressure differences between cold water and hot water and keeps the mixed water temperature constant. If there is no cold water supply, the hot water supply is automatically closed and an anti-scald protection is provided. Using the handwheel, the desired mixed water temperature can be infinitely adjusted. The locking device prevents unauthorized or unintentional adjustment.
