ESPA MULTI SPEEDBOARD Intelligent Pressure Group up to 18.0 m3/h

The compact ESPA pressurization system designed for water supply in domestic applications. The integrated SPEEDBOARD speed controller allows the pressurization system to maintain a constant pressure in the installation. A pressure sensor (transducer), which monitors changes in water consumption, alerts the frequency inverter to change the engine speed, thus adapting operation to the new consumption state. The pressurization system is easy to install. Once installed, simply plug the unit into an outlet and the system is operational.

The compact and silent pressure group. It is ideal for domestic installations or small residential buildings to supply water at constant pressure. This group is equipped with a SPEEDBOARD frequency converter with the aim of maintaining constant pressure. This system, in addition to reducing energy consumption, increases the durability of the electric pump, as its mechanics are not always subjected to maximum speed and do not produce water hammer effects as the starts and stops are progressive.

Operation
It is an Inverter system known as a frequency inverter, it is a more technologically advanced device that maintains the programmed pressure (up to the pump limit) unchanged regardless of the flow consumed.
