VARIO3-30

THREE PHASE VARIABLE SPEED PRESSURE BOOSTER SETS WITH THREE ELECTRIC PUMPS EASY TO INSTALL, LOW ENERGY CONSUMPTION, VERSATILE OPERATION

The new series of variable speed pressure booster sets VARIO3-30 offers a reliable and simple solution for residential and industrial applications.

The system envisages the parallel installation of three electric pumps equipped with electronic control.

The VARIO3-30 is an electronic device designed to vary the frequency of an electric pump.It is incorporated directly on the motor to enable control of the speed to provide the utility with a constant pressure even in the event of changes in water demands.When the system pressure falls below the set threshold, the module starts up the pump to restore the set point pressure; the pump rotation speed varies according to water demand and therefore increases speed on requests for increased quantities, through to the maximum setting. After this, if the system requires more output, the module activates the second pump and then the third to maintain stable pressure values. On decrease in water demand, the speed of the last activated pump is reduced through to shutdown.The module keeps the first activated pump running until the minimum setspeed is reached, after which, if no new water demands are received, the pump is shut down.

The VARIO3-30 is equipped with five operating modes to respond to various operating requirements.
