Geothermal Drilling Rigs and Equipment

Used Geothermal Piling and Drilling machines for Sale

Find a wide selection of geothermal drilling rigs for sale at Sigma Plantfinder, ready to ship worldwide. Geothermal drilling rigs are specialist machines used to drill vertical or angled boreholes for ground source heat pump and shallow geothermal energy systems, tapping into the stable temperatures found just a few metres below the surface for low-carbon heating and cooling. These drilling rigs create narrow-diameter geothermal boreholes, typically drilled to depths of around 50–200 metres, which are fitted with closed-loop pipework so heat-transfer fluid can circulate and exchange energy with the ground.
