Terra Spiral collectors are compact heat exchangers. Thanks to their compact footprint, they reduce the amount of land required. Their installation is simplified by the shallow depth of excavation (3.50 m). This compact collection system is an intermediate alternative between horizontal geothermal collection and vertical probes. The heat transfer tube used in NEO geothermal collectors has an internal spiral structure that reduces the fluid's thermal resistance and pressure losses.
