Home Geothermal (GHP) Drilling Rigs

Dando's Multitec and Sonic drilling rigs are ideal for the drilling and installation of ground loops for geothermal heat pumps. Geothermal heat pump systems have become increasingly popular as an alternative method of providing heating and cooling for residential, commercial and institutional buildings. Considered more energy efficient than traditional HVAC solutions, geothermal heat pumps are much less dependent on fossil fuels for power generation.


Multitec 4000 MK3 Geothermal Rig

The Multitec 4000 is the latest addition to Dando’s line of high performance multipurpose top-drive rotary rigs and is the smallest in the range so far. With a pullback of 4000kgf, the rig is designed to be ultra-compact, lightweight, easily transportable, and capable of a wide range of drilling techniques for the water, mineral, geotechnical and geothermal sectors.



Multitec 9000 Geothermal Rig

With a pullback capacity of 10,000kgf this compact, powerful drilling rig is suitable for water well, mineral exploration, geotechnical investigation and GHP drilling. The rig is track mounted as standard but can also come mounted on truck, trailer or the customer's own support vehicle.

4"RC(25kg/m) drill rod= 400m

3 1/2" (13.5kg/m) drill rod= 740m

H (11.6kg/m) drill rod= 862m

N (8kg/m) drill rod= 1250m


Sonic SDC375 Geothermal Rig

A light, compact multipurpose sonic drilling rig ideal for drilling wells for geothermal/ground souce heat pumps, as well as for water well drilling, mineral exploration and geotechnical investigation.
