Pre-insulated, highly flexible piping system that combines the flow and return medium pipes in the same jacket pipe, especially for the transportation of heating water or other heat-transfer media in underground distribution networks.

The medium pipes are composed of cross-linked PE-Xa and have an orange oxygen diffusion barrier for the flow line and a blue oxygen diffusion barrier for the return. Even with mounted shrink end caps, the colour coding allows for easy flow and return identification during installation.

The multi-layer thermal insulation is made of cross-linked, microcellular PE-X foam with a water-repellent closed cell structure, which is known for its long-lasting, non-aging insulation performance as well as its permanent elasticity, which allows the insulation layer thickness to be maximised even after multiple bends. The high-grade, UV-resistant, double-walled, corrugated HDPE sleeve protects the pre-insulated pipe system from mechanical impacts and moisture while retaining optimum flexibility.
