**COMACCHIO GEO 901 GT** is a dual-head rig for geothermal drilling. Separate drives operate the inner drill string and outer casing, allowing the borehole to be cased as drilling progresses. Equipment is selected for the required diameter, geology and flushing method.

The GEO 901 GT is designed for higher pulling forces and larger casings. Its heavy crawler platform is intended for demanding geothermal and water well projects.
