GEROtherm^® VARIO-RTThe conical, pressure loss-optimised and for elevated temperatures geothermal probe

Principle:

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

Design:‎

The geometry of the 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 PE100-RT-RC*.

Product details

Material

‎Polyethylene PE100-RT-RC* (RT = raised temperature; RC = resistance to crack)

Applications

Temperature range: -20°C / +95°C¹⁾

Pressure resistance: up to PN16 @ 20°C
Dimensions: de 32 mm, de 40 mm

Pressure resistance: up to PN20 @ 20°C
Dimensions: de 40 mm

* Geothermal probes made from PE100-RT-RC is a protected technology. Patent No. CH 717 800 A2.
_{1) The expected durability of the material depends on the duration and temperature of use, along with the inside pressure. The load limits are calculated based on the cumulative damage rule (Miner’s rule) as per SN EN ISO 13760. (For an object-specific definition, the annual frequency temperature profile and the inside pressure must be provided.)}

Advantages

Pressure resistance up to 16 bar or up to 20 bar@20°C
Probe foot (U-bend) resists internal pressure up to 25 bar@20°C
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 2 395 301; EP 2 706 308 and CHF 717 800 A2
On request, the geothermal probe can also be produced on our rental metal reels
