GEROtherm^® DUPLEX-REXThe completely diffusion-resistant geothermal probe with protective layer

Principle:

The completely diffusion-resistant GEROtherm^® DUPLEX-REX geothermal probe prevents the penetration of gaseous substances. The completely diffusion-resistant double-U probe for shallow geothermal use. Resists internal pressure up to PN16@ 20°C and PN20@ 20°C.

Design:

The foot (U-bend) features the same geometry as the double-U probes, but with a vapour-deposited metallic film layer and protective lacquer coating. The core pipe, which carries the medium, is made from state-of-the-art, crack-resistant PE100-RC and is certified to SKZ HR3.26. The pipe’s diffusion resistance is achieved by using a polymer-matrix film with an integral diffusion barrier. It also features a scratch-resistant protective jacket for mechanical protection. This innovation is patented; Patent No. EU 3 450 878.
