HAS GRD 4R
The GRD rig enables HAS to exploit shallow geothermal heat for private households. Thus, single family houses and larger building complexes alike can be provided with the inexhaustible energy from underneath our feet. Only a minimal amount of space is needed when drilling with this unit and it does not cause any environmental damages.
Anger’s exploits geothermal heat with its GRD rig in the same manner as a tree spreads its roots through the subsoil. That means that all drillings are carried out from one single shaft in a 360 degree radius and with different inclinations. This access then guarantees the property owner or landlord a safe source of energy for the next decades, and one that is totally independent from price fluctuations of commodities markets.
