Flexalen® 600 HP is an extremely flexible, pre‑insulated piping system engineered for mono‑block heat pump connections and building‑to‑building links.
Extreme flexibility for fast, safe heat pump connections.
Flexalen® 600 HP simplifies mono-block heat pump installation by combining heating distribution and electrical cable routing in one compact, pre-insulated system. The corrugated PE casing, polyolefin foam insulation, and PB-1 service pipes deliver high pressure and temperature resistance (rated 95°C/8 bar) and superior moisture protection, while the integrated electrical conduits eliminate separate cable trenching, reducing both installation time and project cost.
For projects that require a straightforward, pre-configured pipe run without integrated cable conduits, the Flexalen® 600 Short Length Package (SLP) is available as a complementary solution within the same product family. Built on the same proven Flexalen® 600 platform, the SLP delivers an all-in-one pre-insulated double-pipe set, ideal for point-to-point connections between heat pump units and adjacent buildings.
