The STEADYPRES TT 8 inverter from Pedrollo is used for water supply in residential, commercial and irrigation sectors.
It is applied to the delivery of the electric pump and modulates the output voltage value, allowing the motor speed to be varied based on the quantity of water required.
Flexible in its use, it adapts to any type of pressurization system, even existing ones.
The STEADYPRES TT 8 consists of a frequency converter, pressure and flow sensor, panel with keypad and display and a non-return valve.
It has several features that allow you to protect the system from dry running, overcurrent, overvoltage, undervoltage and short circuits.
Easy and simple both in installation and programming thanks to the comfortable keypad and display and the intuitive user interface.
