The new standard for geothermal infrastructure
The demands placed on modern geothermal projects are constantly increasing: higher loads, more complex installation situations, shorter construction times, and increasing cost pressure. At the same time, many geothermal wells still rely on principles that date back to a time when material mass was synonymous with safety.
With the GN X, GNV GmbH is fundamentally challenging this principle — and defining a new standard for geothermal wells.
When mass becomes a burden
Traditional Pipe Winding Chambers and concrete shafts undoubtedly offer stability. But this stability comes at a price:
- high costs
- high dead weight
- complex logistics
- large installation depths
- long delivery times
In practice, these factors often lead to higher overall costs and limited planning freedom — especially for complex or inner-city projects.
So the question is no longer: “Can the shaft withstand this?” But rather: “Is there a smarter solution?”
The GN X: Performance through design rather than material mass
The GN X takes a consistently different approach. Instead of mass, it relies on an intelligently constructed, statically optimized design that reinforces exactly where it is needed.
The result:
- Trafficability up to 40 tons
- Load classes B125 to D400, partly without load distribution plate
- Integrated buoyancy control in case of standing water
- Up to 100 probe circuits in one chamber
The GN X shows: High load-bearing capacity is not achieved by using more material – but by better construction.
Load class B125
Flexibility that simplifies planning
Another key advantage of the GN X is its exceptional flexibility. With four available sizes, 750 mm telescoping, and an extremely low installation depth of only 1069 mm, the chmaber adapts to a wide variety of project situations.
For planners, civil engineers, and project developers, this means:
- Fewer special solutions
- Less excavation
- Greater planning reliability
A shaft that covers numerous applications—without compromise.
Cost-effectiveness throughout the entire project
The economic advantages of the GN X are evident not only in the product price, but along the entire value chain:
- Lower weight → simpler logistics
- Lower installation depth → shorter construction times
- Modular design → fewer additional components
- Short delivery times → better project management
As a result, the GN X is significantly cheaper than classic spiral pipe or concrete shafts – while offering higher technical performance.
Proven in practice – across Europe
The GN X is not a theoretical innovation. More than 50 customers in Europe are already using it successfully in real geothermal projects – from residential construction projects to commercial applications and demanding infrastructure projects.
This practical experience confirms what the design promises: reliability, safety, and cost-effectiveness in everyday construction site use.
GN X vs. coiled pipe & concrete – a brief comparison
| GN X Series | pipe winding & concrete | |
| Performance | Up to 40 t, B125–D400, up to 100 probe circuits | Same performance, but with additional weight and effort |
| Design vs. weight | Performance through intelligent design | Performance through material weight |
| Installation | Low installation depth, telescopic, quick installation | Deep excavation, complex, slow |
| Cost-effectiveness | ignificantly cheaper over the entire project | High material, logistics, and installation costs |
| Practical application | Proven with over 50 customers in Europe | Standard solution without any innovative advances |
THINK X – a new way of thinking about infrastructure
The X series exemplifies the philosophy of GNV GmbH:
Reducing complexity, lowering costs, and increasing quality at the same time.
THINK X means not simply adopting existing standards, but critically questioning them – and developing better solutions.
Conclusion: The GN X replaces classic geothermal shafts
The GN X is more than just an alternative product. It is a logical further development of the geothermal manifold chambers – technically, economically, and practically.
One chamber. All loads. GN X – the new standard for geothermal energy.
