Earlier this month, we delivered and installed two XG12 automatic bar screens at a wastewater treatment plant in Luxembourg. The main feature of this project was the depth of the installation, i.e. 15,500mm. The time required for the shovel/carriage combination to complete a full cycle (lowering-cleaning of screen-raising and ejection of waste) is 3min and 50s.
