The compact drilling rig for shallow geothermal work. Cased heat-loop bores in overburden soil, up to 300 m per individual probe length. Primed for the use of a downhole hammer.
Increased performance
The latest design stage allows -among others- a usable length of 4 metres (@ 100 kN retraction force) for double rods and the attachment of a loading crane above the right-hand crawler.
High drilling power
In combination with the motor-side power rating of 129 kW, the pump output for faster drilling progress has been increased as compared with previous models.
