LEGEND
For correct operation of the pressurization system, we recommend the use small size pressure tank. It is necessary to stabilize any pressure
fluctuations during the variation frequency of the inverter.
Pay attention to the calculation for pre-charge of the pressure tank. In case of changes in the reference pressure, the pre-charge of the tank must
be adjusted according to the calculation.
Pp = Pre-charge pressure
Ps = Setpoint pressure
Dr = Delta restart pressure
Pp = (Ps – Dr) – 0,5 bar
