Expansion tank

The expansion tank is initially used to compensate for the variations in volumes that the installation's body of water undergoes due to temperature fluctuations.

The second role of the expansion tank is to maintain the pressure in the installation when it is completely cooled. In this case the pressure of the vessel must prevent a vacuum in the installation and thus the penetration of air source of corrosion

There are two types of expansion tanks:

- closed at variable pressure
- open

The Massal tank offers you its range of open expansion vessels.
