Neptune is an electronic device that controls the start and stop of an electric pump, based on inverter technology.
Thanks to this technology, it is able to modulate the frequency (Hz) of the current that reaches the motor in order to vary the speed of rotation rpm according to the demand for water from the system.
Mandatory installation of a 2-5 liter expansion tank.
Motor output ampereometric control.
Constant pressure thanks to motor speed regulation.
Energy saving thanks to lower pump absorption.
Gradual starting and stopping of the pump reduce water hammer.
Dry-running protection Automatic reset in case of dry-running.
Leakage control Anti-block function.
Possibility to connect more devices to the pressurization group up to 8 pumps.
