PE-Xa Probe

The REHAU PE-Xa probes, where only the ultimate solution will suffice.  Extremely tough and able to handle temperatures up to 95°C (perfect for excess heat storage such as solar - increasingly required feature of new builds); the PE-Xa really is the next generation of probes.

Furthermore, such is the strength and durability of the PE-Xa probes we are able to offer a £10,000 consequential loss per PE-Xa probe installed. Contact us for more details.

The tight bending radius of of PE-Xa allows a jointless probe tip: no joint means no potential leakage.  PE-Xa is also resistant to puncture loads which can occur when a probe presses against the borehole wall, potentially causing pipe failures.  Notches and grooves can also easily occur during pipe transit, storage and installation but due to the improved physical properties of PE-Xa, notches can travel 20% into the pipe wall and still not affect the pipe lifespan.

Available in sizes up to 800m.

Advantages of the RAUGEO PE-Xa Probe:  

• No need for joints in the soil ensures highest operational reliability
• PE-Xa material is not sensitive to notches and grooves
• Optimal safety during insertion into the borehole
• Simple insertion even into the tightest boreholes
• Constant operating temperatures -40°C to 95°C
• Stable up to temperatures of 95°C, thus the RAUGEO PE-Xa probe can be used for heat storage purposes
• Extremely tight bending radii
• No need for sand backfill, simply use as dug material. – Thereby reducing requirement for lorries carrying imported backfill 
• Probe base is protected by a special tough resin
• Can be connected by means of electrofusion sleeve or by means of REHAU – compression sleeve under all climatic conditions.
• Residential or Commercial - Geoexchange cooling / heating system or ground energy storage (solar energy, waste heat)
• Crack growth at FNCT (full notch creep test) - NO FAILURE
• £10,000 consequential loss cover per probe
