The Combi 300 B is pre-eminently a machine for challenging ATES projects in geothermal energy and water extraction processes. With a reach of more than 250 meters for suction airlift drilling and its enormous power, this Conrad Combi 300 has proven to be a very reliable installation.
Overview
UNIQUE COMBINATION OF FACTORS
The Combi 300 B offers outstanding performance in challenging CHP projects in geothermal energy and water extraction processes. With a reach of over 250 metres deep for suction and airlift drilling and incredible power, this Conrad Combi 300 has proven to be the ultimate reliable machine. It is an outstanding performer in flush and suction drilling and suction drilling with airlift and offers so many pump assembly, compressor, accessory and even rotary table options.
Compared with the Boxer 200 B, you also really notice that extra power, both in the hydraulic systems as well as in the pumps and diesel engine. It makes the Combi 300 B unbelievably effective.
