Integrated pressurization system consisting of two vertical multistage electric pumps and an inverter. Ideal solution for pressurizing homes, villas and condominiums where constant pressure and good flow rates are required. Also excellent for civil and industrial applications.

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 over current, 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.
