Description
RAUVIPEX DUO 50mm – 441031
RAUVIPEX DUO 50mm is a pre-insulated twin pipe system designed for underground heating applications with higher heat demands. It combines flow and return pipes within a single insulated casing.
The twin-pipe arrangement supports installation of combined flow and return pipework within one trench, reducing excavation compared to separate single-pipe installations. The insulated construction helps limit heat loss over longer underground distances.
This size is typically used for larger underground heating networks, longer pipe runs, or systems supplying multiple buildings from a central energy centre.
RAUVIPEX DUO 50mm is compatible with REHAU-approved jointing systems. It is commonly specified for underground heating pipework where capacity and long-term reliability are required.
