GEROtherm^® VARIOThe conical pressure-optimised geothermal probe

Principle:

Double-U probe for shallow geothermal use. Resists internal pressure up to PN16 at 20°C and PN20@20°C.

Design:‎

The geometry of the probe foot (U-bend) is identical to that of the DUPLEX double-U probes. Optimised probe pipe with the same outside diameter as the DUPLEX double-U probes with variable wall thickness made from PE 100-RC.

Product details

For further product details, please refer to the corresponding Technical datasheets or the Flyer.

Advantages

Pressure resistance up to 16 bar or 20 bar
Probe foot (U-bend) resists internal pressure up PN25
Optimised hydraulic pressure loss and therefore more efficient overall systems
100% plastic for better corrosion resistance
Significantly improved buckling pressure resistance in the lower section
Same diagonal dimension as DUPLEX probes
Compatible with the GEROtherm^® weight system, the GEROtherm^® PUSH-FIX impact-resistant sleeve including weight connector and the GEROtherm^® UNI-FIX universal weight mounting
Proven mud container in probe foot (U-bend) with two new ribs that make it easier to use a measuring float
Installation conditions similar to those for standard probes
Patent No. EP 2 706 308
SKZ certified and monitored SKZ certificate No. A278
Certified and monitored by KIWA KOMO certificate No.: K84660/02
