AWADUKT Thermo

Air-ground heat exchanger system for the regulated ventilation

The air-ground heat exchanger AWADUKT Thermo uses the heat source capability of the ground. At a depth of 1.5 m the heat is constant 8-12°C. A network of pipes can harness the energy to heat and cool a building.

REHAU developed the first air-ground heat exchanger with an anti-microbial pipe inner layer. In combination with heat recovery devices, owner can save not only money and energy, but also improve the air quality in their building significantly.
