GEROtherm^® VARIO-REXThe conical, pressure loss-optimised and complete diffusion-tight geothermal probe with protective layer

PRINCIPLE:

The conical, pressure-optimised and complete diffusion-tight GEROtherm^® VARIO-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 PN20@20°C.

DESIGN:‎

The foot 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 conical 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 und EP 2 706 308

Advantages

Pressure resistance up to 20 bar
Greater resistance thanks to reinforced walls on probe foot (U-bend); PN25
Optimised hydraulic pressure loss and therefore more efficient overall systems
Significantly improved buckling pressure resistance in the lower section
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. EU 3 450 878 and EP 2 395 301
