FRANK VTP for geothermal energy
Effective geothermal use of the ground in case of limited borehole drilling depth
The FRANK VTP® (Vertical Thermpipe) is a near-surface geothermal system designed for use in areas where drilling depths are limited. It has been specially developed for areas where conventional geothermal probes cannot be used due to regulatory, technical or economic restrictions.
Unlike conventional geothermal probes, the FRANK VTP® does not operate at great depths; instead, it uses the upper subsoil for specific heat extraction purposes. Suitable extraction capacities for renewable energy can be achieved at drilling depths of just 6 to 12 metres.
This makes the system ideal for locations where deep drilling is not possible, opening up new applications for geothermal energy.
Factory-prefabricated FRANK VTP® elements enable simple, fast and reliable installation. The shallow drilling depths allow cost-efficient drilling methods to be employed, such as with hollow auger drills.
With a design life for generations, the FRANK VTP® offers a durable, cost-effective solution for using renewable energy, free from the typical requirements and restrictions of conventional geothermal probes.
The benefits of FRANK VTP®:
- Ideal for shallow drilling depths and for use in areas with groundwater flow
- High heat extraction rates are possible
- Extremely fast installation
- Completely pre-assembled element which can be installed without preparation
- Small drill diameter required
- Fixed heat carrier pipe spacing
- Safe connection of connection pipes with electrofusion welded fittings
- Pressure-tested with test certificate
- 6 m , 9 m and 12 m Installation lengths
- Other lengths on request
- Inner diameter can be extended as a well
- Inner diameter can be used for infiltration of rainwater
