LORO-X Series 43 model DUOFLUX pipe-in-pipe

The LORO-X DUOFLUX ® main-emergency-combination pipe-in-pipe parapet drainage safely drains the water from the parapet roof. Only 1 drain and 1 parapet opening are required for the main and the emergency drainage.

Main drainage

In the case of normal rain, the main drainage takes place via the “lower” drain basin with a DN 100 drainpipe for the main drainage through the branch into the ground pipe.

Emergency drainage

In the event of heavy rain, the emergency drainage starts additionally via the "upper" basin with a DN 50 drainpipe for the emergency drainage. The inside DN 50 drainpipe is routed directly through the branch as a spout.

Further information can be found in the Aktuell 118.
