Description

REHAU RAUVITHERM DUO Pre-Insulated Pipe

REHAU RAUVITHERM DUO is a flexible twin-pipe pre-insulated PE-Xa pipe system designed for the efficient distribution of heating water in heat pump installations, district heating networks and renewable energy applications.

Featuring two PE-Xa carrier pipes within a single insulated casing, RAUVITHERM DUO provides a convenient solution for flow and return heating circuits while reducing installation time and minimising heat loss. Its highly flexible corrugated outer jacket allows for easy routing around obstacles and enables faster installation with fewer underground joints.
