Vertical geothermal probe GEROTHERM® DUPLEX-REX

The completely diffusion-resistant geothermal probe with protective jacket The completely diffusion-resistant GEROtherm® DUPLEX-REX geothermal probe prevents the penetration of gaseous substances. The double-U probe for shallow geothermal use. Resists internal pressure up to PN16 at 20°C and PN20 at 20°C. The foot (U-bend) features the same geometry as the double-U probes PN20, 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. Core pipe made from PE100-RC (RC = resistance to crack); polypropylene PP protective jacket Temperature range: –20°C/­+40°C Pressure resistance: PN16 at 20°C/­SDR 11 Dimensions: de 35 mm, de 43 mm Pressure resistance: PN20 at 20°C/­SDR 9 Dimensions: de 43 mm Greater resistance thanks to reinforced walls on probe foot (U-bend); PN22 Compatible with the GEROtherm® weight system‎, the GEROtherm® PUSH-FIX impact-resistant sleeve including weight connector and the GEROtherm® UNI-FIX universal weight mounting Larger cross-sections and welded coupler sockets for lower hydraulic resistance Proven mud container in probe foot (U-bend) with two ribs that make it easier to use a measuring float No need for welding on site DIN EN 12201-2 Patent No. EP 2 395 301
