Electronic Variable Speed Pump Controller

Sirio is an electronic device based on inverter technology that maintains constant system pressure by regulating the starting and speed of the pump.

Inverter technology modulates the frequency (Hz) of the current to the motor which changes the speed (rpm) to suit the water demand from the system. This means that water is delivered to the user at a constant pressure and the motor power consumption is always in proportion to the system demand, resulting in notable energy savings over time.

For correct operation this Sirio controller requires a pressure vessel to be used in conjunction with it. These are available from us please contact us to ensure the correct size vessel is used for your application.
