The Combi 300 GT is pre-eminently a machine for challenging projects in geothermal energy. With a range of more than 350 meters and its enormous power, this Conrad Combi 300 has proven to be a very reliable installation.




The Combi 300 GT offers outstanding performance in challenging geothermal energy projects. With a reach of over 350 metres depth and incredible power, this Conrad Combi 300 has proven to be the ultimate reliable machine. It offers so many options in terms of pump design and can also be equipped with the double drill head that Conrad developed for cased drilling. The Combi 300 is also suitable for 5-metre-long drill pipes.

Compared with the Boxer 200 GT, you really notice that extra power both in the hydraulic systems as well as in the pumps and diesel engine. This makes the Combi 300 GT the perfect solution for projects requiring just one deep drilling, with high efficiency for multiple users, such as homes where outside space is limited. 


Operation convenience

Despite the dimensions, this machine is also delivered with a rotating frame, manipulator and remote control, and the entire drilling process can be controlled by one drilling operator. And with 350 metres of drill pipes on deck, you can really get to work.

The Conrad Combi 300 GT can be fitted with the Conrad CCR, a de-sanding unit that ensures a cleaner drilling process, uses considerably less water and delivers significant material savings. The CCR assigns large drilling bins and rinse tanks to history and the drilled material can be disposed of dry.
