This range of Geothermal Rigs is designed to give access to restricted sites but have the capable of drilling bores 180mm (7") to 76mm (3") in diameter and over 200m (650') deep. The rigs can use rotary drilling with fluid or air flushing. Hard rock can be drilled with Down the Hole Hammers and casing systems if needed. Geothermal rigs from Techno Drill are the most cost effective on the market for any type of drilling conditions. The size of the rigs makes transportation simple and reduces the environmental impact to the drilling site.
