HOT WATER TANKS

  • CAL - PRO

    CAL - PRO

    Diaphragm expansion vessels for centralized closed circuits. Suitable to compensate the increase of volume of hot water.

    Endowed with a synthetic rubber membrane (SBR), they’re approved and manufactured according to the Directive 97/23/CE, for hydronics and non-potable water.

  • Ultra

    Ultra

    Interchangeable butyl membrane vessels for potable water. Their usable capacity is superior than that of ordinary tanks: less volume is needed.

    The tank is constantly kept under pressure by a air cushion that is separated from water by the membrane: no air supply is therefore necessary.
