Specifically, we deal with an expansion vessel for sanitary water use and membrane autoclaves. The air pre-charge pressure must be checked with the hydraulic circuit at zero pressure, as if the expansion vessel were disconnected from the circuit. The pre-charge pressure or the minimum and maximum pre-charge pressure range are indicated on the product plate. Usually for residential use the pressure is about 1.5bar, but it can and must in some cases be increased or decreased, according to the maximum pressure of the hydraulic circuit.
