Geotec knows the drill

Geotec Bohrtechnic GmbH of Nordkirchen, Germany is a leading producer of high-quality vertical drilling rigs used in construction, geothermal energy extraction, geotechnical engineering, mining, well development and many other applications. Their Rotomax products are expected to perform under difficult conditions, in remote locations, and on projects with stringent time constraints.



Geotec has chosen Perkins® 1200 Series engines for more than 800 different machine models over the years for their performance and reliability under demanding conditions.

For example, a Geotec Rotomax XL-B rig was used to drill geotechnical exploration bores in a feeder tunnel from Munich to the Brenner near Kufstein in Tyrol. The surface location was 890 m above sea level on the German/Austrian border, but the actual drilling was done in a location 160 m below ground level.

The rig was powered by a 4-cylinder Perkins® 1204J-E44TTA diesel that meets EU Stage V emission standards and produces 140 kW and 825 Nm of torque. It ran 24 hours a day continuously for six weeks to complete the project on-time.

The same engine powered a Rotomax XL-GT rig used to drill geothermal bores for a Welch housing estate that included multiple solar plants. And, a 6-cylinder version, the Perkins®  1206J-E70TTA, powered Geotec’s larger XL-GT Ci rig using a double-head drill to produce a service water well for a horse stud farm in another Welch project.

Geotec is supported by their Perkins authorised distributor, BU Power Systems.

“We benefit from good advice - no matter whether it's about choosing the right engine for our drilling equipment, to service and spare parts availability. BU Power Systems, supports us reliably and competently at all times,” says Geotec managing director, Norbert Zumholz.
