Type-tested statics as the key to planning reliability in geothermal projects
Planning modern geothermal projects has become increasingly demanding.
Rising load requirements, complex standards, limited space and economic pressure all converge in an infrastructure environment that still often relies on concepts developed for much smaller and simpler projects.

Especially when it comes to the geothermal chamber, a fundamental challenge becomes apparent:
complexity is frequently addressed through mass rather than through design.
GN X follows a different approach – one that reduces complexity where it originates: in the planning phase.
Why geothermal shaft planning has become so complex
Planners and engineers face a wide range of questions when designing geothermal infrastructure:
- Which load class is required?
- How is traffic load structurally verified?
- How is buoyancy addressed in areas with groundwater?
- How many probes can be efficiently bundled in one shaft?
- How can project-specific special solutions be avoided?
With conventional solutions, these questions often lead to:
- project-specific structural calculations
- individual special designs
- increased coordination with testing and approval bodies
The result is high technical and organisational complexity long before construction even begins.
Type-tested statics: from project risk to product feature
One of the key differentiators of GN X is its proven type-tested static design.
While many conventional shafts require project-specific structural verification, GN X is based on a certified, standardised static design.
Its load capacity of up to 40 tonnes is clearly defined, reproducible and calculated for a service life of 50 years.
For planners, this means:
- clearly defined load capacity
- reduced coordination effort with approval authorities
- lower structural risk
- greater planning certainty
Structural safety becomes a product characteristic, not a project variable.

The standardized type statics and clear boundary conditions of the GN X series not only reduce the effort involved in the current tender — follow-up projects can also be processed more quickly and with less coordination.
Once understood and established, the GN X chamber becomes a reusable planning solution rather than a one-off case.
Design instead of special solutions
The GN X achieves its high load capacity not through excessive wall thickness or material mass, but through an intelligently optimised structural design.
This design enables:
- controlled load transfer
- compact construction
- high stability with significantly lower weight
At the same time, it reduces the need for:
- additional load distribution plates
- oversized concrete structures
- project-specific special details
For planners, this results in fewer variants, fewer interfaces and greater clarity.
Technical flexibility for real-world projects
Beyond structural performance, flexibility in day-to-day project execution is crucial.
The GN X is designed with exactly this in mind:
- different sizes within one product family
- very high number of probes per shaft
- compact installation depths
- clearly structured hydraulic layouts
Instead of combining multiple shaft concepts, many project requirements can be met with a single, consistent solution.
This reduces:
- interfaces between trades
- sources of error
- coordination effort
From specification to tender: clarity instead of interpretation
Another often underestimated advantage lies in tendering and specification.
Thanks to:
- defined type-tested statics
- clear technical parameters
- documented load classes
The GN X can be precisely described and objectively compared in tenders.
For planners, this means:
- less room for interpretation
- clearer bids
- higher comparability
Good planning does not stop at design – it continues into procurement.
Planning means responsibility
Geothermal systems are long-term infrastructure investments.
Errors or uncertainties in the planning phase can have consequences lasting decades.
GN X helps reduce these risks by:
- standardising structural safety
- reducing technical complexity
- aligning planning and execution
Not by lowering requirements,
but by improving the underlying design logic.
Conclusion: Less complexity is not accidental
The GN X demonstrates that planning reliability is not the result of additional components, but of consistent product engineering.
With proven type-tested statics, intelligent load transfer and a clearly structured technical concept, GN X delivers exactly what modern geothermal projects require:
Planning that holds.
