Integrated pressurization system consisting of two multistage electric pumps and inverter. Available in the double version with vertical or horizontal electric pump. Ideal solution for pressurizing homes, villas and condominiums where constant pressure and good flow rates are required.

Plug & Play system, with a single inverter that is easy to configure for the management of 2 electric pumps, both at variable speed. Reductions in consumption and always constant pressure. Protection against dry running and automatic reset, protection against overcurrent, abnormal supply voltages and short circuit between system output phases. Possibility to view the log of operations and alarms.

The SPEEDBOX DUO inverter modulates the frequency of both electric pumps and manages their simultaneous operation with alternating restarts.
