Rehau’s Nexus is said to be the world’s first system for hot-tapping PE-Xa district-heating networks. It makes it possible to retrospectively extend an existing heat network or add a ventilation or measuring point to a district-heating system using Rehau orange PE-Xa pipes.

Expansions can be carried out during operation and under pressure without disrupting the supply, making such connections up to 80% quicker. Installers also need only half the installation trench space compared to conventional squeeze-off techniques, saving on civil costs.

Nexus connections are suitable for use with Rauvitherm and Rauthermex PE-Xa pipe systems, underground and in a plant room. Nexus is made in accordance with EN 15632 and has a minimum life of 30 years, thanks to its corrosion-resistant design.
