In the Netherlands, deep drilling for geothermal systems is often restricted – among other things to protect groundwater and due to existing gas reserves. But even with limited drilling depth, geothermal energy is possible:separatus Energy pilesoffer a clever and efficient solution for this.
Ideal conditions for energy piles
Especially in regions with sandy soils and high groundwater tables, the conditions are optimal for the use of energy piles. Pile foundations are used for thegeothermal energytoUsedand at the same time theLoad capacityof the soilImprovement– especially where settling is expected due to soft soils or high water levels.
separatus uses this structural advantage twice: The piles perform not only static but also thermal tasks. The patentedsplitpipe systemis specifically designed for these requirements and enablesShort, efficient circuits– ideal for flat installation depths with high performance at the same time.
First separatus plant in the Netherlands
We are pleased that theFirst separatus plant in the Netherlandsis implemented. Prefabricated, reinforced concrete piles with a square cross section of 40 cm are used. In order to reduce transport weight, these are hollowed out inside.
In this cavity, theseparatus probeand subsequently backfilled with thermally conductive material. Thus, thenarrow cavitywith a diameter of only 25 cm efficiently developed for the use of geothermal energy. Thus, the pile is simultaneously as a supportingComponentand asHeat exchanger used– a double benefit that convinces both economically and technically.
System Construction: Efficient and thoughtful
The installation shall include:33 Energy pileseach of which is8 metreslong separatus probes. These are connected to the heat pump in four probe circuits:Three circles consist of eight probes, a fourth of nine probes. Thus, a total length of264 metres vertical borehole heat exchangers– and that at a comparatively low installation depth.
A particular advantage ofseparatusSystems is hisHydraulic optimisation: Even with short circular lengths, the brine fluid quickly reaches theturbulent flow regionwhich intensifies heat exchange and significantly increases energy efficiency.
Horizontal connection contributes to efficiency
The probes are connected via standard hoses with 32 mm diameter in the horizontal. These are not only responsible for the hydraulic connection, but also contribute to the thermal activation of the substrate.
In these lines, too, a heat exchange takes place with the surrounding soil – This increases the active exchange area, whichOverall efficiency of the plant further increased.
Pre-assembled for easy and quick installation
Theseparatus probesincluding connection lines were delivered directly to the construction site as prefabricated bars. TheSaves time and logistics effortand enables a particularly smooth and fast installation.
The installation is very simple: The probes are inserted directly into the prepared energy piles – without any special tools or complex assembly. Thanks to this well-thought-out logistics and easy handling, the installation time can be significantly reduced compared to conventional energy piles – and thusCost savings.
Trust and enthusiasm on the ground
A big thank you to our sales partner in the Netherlands,Jeroen Van Der MeijdenfromGeothermal BV– for the trust in our solution, the committed cooperation and the warm hospitality during our visit.
Spoiler alert:Jeroen was so convinced of the system that he directlyseparatusProbe installed in his new office building. We will present this project soon!
We really enjoyed the visit to the Netherlands – and are already looking forward to theNext installation of separatusAs a perfect occasion to return.
