AWADUKT Thermo is a ground-air heat exchanger system, also known as earth tubes, for pre-tempering ventilation air. Ventilation air is drawn through underground pipes buried at a depth of 1.5m, which pre-cools the air in the summer and pre-heats it in winter, using the near constant temperature of the ground (7-13°C).
The system has been extensively used across the UK in commercial projects, mainly in the education sector. The system is ideally linked up with a mechanical ventilation unit with heat recovery (MVHR) to offer a full ventilation solution.
Also used for domestic installations. The system is ideally linked up with a mechanical ventilation unit with heat recovery (MVHR) to offer a full ventilation solution. Different domestic packages are available for different size properties.
