Application:

Preinsulated pipes Inflex Thermal are specifically designed for ground heat pump systems (GHPS), to transport liquid from heat exchanger to heat pump (Inflex Thermal).
The system consists of an HDPE pipe insulated with flexible foam and enclosed in a corrugated pipe for outside protection. A multilayer layer of soft foam EPE provides excellent thermal insulation in a wide temperature range. Insulation’s closed-cell structure prevents water absorption and water vapour permeability, and is resistant to mechanical deformation.
Pipes are highly corrosion-resistant, pressure and temperature resistant (up to 40°C). These pipe has high mechanical strength (500 N), high-impact resistance and flexibility which makes them easy to install. Pipes are also recommended for other cold water industrial applications.
Pipes are available in 6 meter straight lengths and in coils of 25, 50 and 100 meters.
