INVERTER (VFD) DUTY BOOSTER SYSTEMS TYPE BV

The basic theory of operation ,for the booster systems operating with INVERTER , is a common one with the usual booster systems. The diifference of the operation is that it is driven by a variable frequency driver (INVERTER) placed in a control panel or mounted on the electric motor of each pump unit. Control is achieved by pressure sensors with a steady state of the system pressure up to 0,1 bar.
