Ground Heat Exchangers

Ground Heat Exchangers or Earth Tubes are used in the ventilation, heating and cooling of buildings. This is achieved by passing air below ground through an underground tube; the temperature below ground is lot more stable compared to the extreme outside temperatures, thus allowing the building to be cooled or heated. Precast concrete pipes have been used for this purpose around the world because they have good thermal conductivity to the ground and CPM can provide concrete pipes and shafts to suit any design required.
