    Expansion vessels

    The expansion tank is a hydraulic component which has the function of containing sudden changes in circuit pressure, avoiding sudden changes and water hammer, which otherwise would have to be absorbed, with possible damage, by the system.

    Due to its constructive logic it is sometimes simply called "lung" that is the inflatable membrane that acts as an air chamber which however is only the central element of the vessel.

    The main uses of expansion vessels are:

    • In domestic boilers, to compensate for pressure variations due to temperature differences or a sudden change in flow
    • In automobile cooling circuits, also here to compensate for the effects of thermal expansion.
    • In irrigation systems, both to avoid water hammer and to facilitate pressure regulation by means of a pressure switch that controls the pump motor.

    There are 2 types: closed expansion vessels and open expansion vessels.
