**COMACCHIO GEO-T 20 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-T 20 GT is truck-mounted, combining dual-head drilling with road mobility. Different chassis configurations and mast lengths allow a project-specific layout.
