Circulator 7 bars

USE

Hot-water heating systems
Domestic and commercial buildings.The electronic controls allows for setting advanced features

Wet rotor high efficiency circulator, driven by a permanent magnets synchronous motor (PM motor) controlled by an on board inverter.
The motor is protected against overload thanks to a thermal protection and an automatic electronic release function of the rotor.
No external protection is required.
Operated by selector technology.
ErP 2009/125/EC Standard.
Automatic speed control system able to adapt to the changing needs of the system. The circulator delivers the performance you need with minimum energy consumption
Automatic unlocking programme
Automatic detection of air
