VR 12 ltr. diaphragm expansion tank heating pressure expansion tank VR MAG
Item number 40284
Structure of the pressure expansion vessel
The expansion tank with exchangeable membrane is suitable for heating and cooling systems. The vessel provides the necessary space to compensate for the expansion of the heating water by increasing the temperature and thus avoids damage to the system.
- Volume 24 litres
- Operating temperature -10 °C to 100°C
- Colour RAL 3000 (red)
- Rubber membrane made of EPDM
- Counterflange galvanized
- vessel without feet
- Inlet pressure 1.5 bar
How it works
After commissioning the diaphragm pressure expansion vessel, it takes over the function of regulating the water expansion in heating mode.
At max. temperature and pressure load of the diaphragm it occupies almost the entire interior. The membrane prevents any contact of the heating water with the surface of the vessel.
When the temperature drops, the water valumen is reduced. The counterpressure in the vessel forces the heating water in the membrane back into the system. Samit a stable pressure of the plant is ensured. This process is repeated constantly during operation of the system.
