Flexalen® Multiline combines 3 to 4 service pipes in a single insulated channel, ideal for heating, hot water supply, and recirculation in one pre-insulated system. Saves space, reduces wall penetrations, and speeds up installation for building-to-building connections, heat pump links, and small stand-alone networks. Fully compatible with Flexalen 600. Max. 95°C/8 bar.
A pre-insulated piping system that routes multiple services—heating flow/return, domestic hot water, and optional recirculation lines—together in one flexible, robust jacket pipe. It features closed-cell polyolefin foam insulation and corrugated PE casing for high moisture resistance and mechanical protection. Individual service pipes can be easily replaced or added without disturbing other lines, offering flexibility for future system upgrades.
