The Comacchio GEO line of water well and geothermal drilling rigs embraces an extremely diversified selection of eleven models. It ranges from lightweight and small footprint units ideally suited for tight work sites, usually associated with residential and small-scale commercial geothermal and water well drilling projects, to heavy-duty machines with up to 50 tonnes pull up capacity, reaching over 1000 m drilling depth.
The Comacchio GEO line drill rigs are designed as multipurpose units, able to meet the different requirements and needs related to water well and geothermal drilling projects. Thanks to their flexible design, based on the use of advanced modular hydraulic circuits, these machines can adapt to all of the most commonly used drilling techniques, depending on borehole diameter, required drilling depth and soil conditions on-site, including:
rotary drilling with direct air/water/mud flushing;
reverse circulation mud drilling;
rotary-percussive drilling with down-the-hole hammer (DTH drilling).
The development of a wide range of rod handling systems has allowed mechanizing and automating, partly or completely, the handling of rods, increasing safety levels and productivity.
The range of uses of these machines include installation of piezometers and groundwater monitoring wells, construction of wells for public, agriculture, commercial, industrial and domestic water supply, installation of geothermal probes, along with well repairs and deepening.
