SBR Control units
Discover the control units for SBR treatment plants, submersible pump treatment plants and airlifts treatment plants.
These control units can manage ECO and Normal modes, the majority support water level measurement by pressure detection, so a float switch is no longer required.
The control units are easily programmable, the latter can be carried out by BIBUS France or by yourself.
