Where's the magic?
Extruder
In loose grounds, Grabowski automatically extrudes a pipe to support the stability of the borehole.
Fluid muscles
Grabowski's system of fluid muscles allow it to move up and down the borehole as well as seal it in emergencies.
Drill bit & gearbox
A unique gearbox design coupled with two engines for rotation and hammering break down any type of rock.
Grabowski Fact Sheet
Compact
With its 135 mm diameter and length of 2.5 m, Grabowski weighs less than 150 kg. In total, it requires 6-8 m2 to operate - 84% less than the competition.
Silent
At less than 60 dbA, Grabowski drills 94% quieter than the competition. Once in the ground, it is barely audible.
Gentle on the earth
No need for diesel, Grabowski simply plugs into the wall. Its 288 kg of CO2 emissions per borehole are 86% less than the competition.
Smart
On its way down, Grabowski automatically detects different layers of earth including water tables. In case of artesians, it seals the borehole shut.
Automated
Grabowski is the first geothermal drill to be completely automated. It is installed by a single worker and automatically proceeds to make its way down.
Guided
Grabowski drills down straight without any offset. It tracks its every movement allowing for close placements of multiple boreholes.
Future, we are ready for you.
About 3.2 million geothermal heat pumps will be installed in Switzerland and Germany by 2035. Our robot can do away with all the conventional disadvantages.
