To visit the Z-10 nuclear shelter in Brno is a fascinating experience.

Immerse yourself in the depths of Cold War history. This unique space, originally built to protect against nuclear threats, is now a valuable memento. It is in this historic environment that the past is combined with modern technological solutions that ensure its current smooth operation.

Air for history: Our role in Z-10

To maintain optimal conditions for visitors and protect exhibits in underground spaces, it is essential to ensure effective and reliable ventilation. Even in such a unique and demanding environment as the Z-10 atomic shelter, modern systems play an important role.

We are proud to announce that our Ventiair BK TYPE 20 heat recovery unit has been installed to ventilate the shelter.

The installation of our unit in Z-10 proves that modern HVAC solutions are flexible and capable of operating even in the non-standard conditions of historically valuable buildings:

• Reliability: The unit ensures constant and controlled air exchange, which is critical for maintaining a high-quality indoor environment underground.
• Energy efficiency: Despite specific ventilation requirements, heat recovery helps minimize energy losses, which is key to the economic operation of the shelter.
• Quiet operation: Discreet operation is important in areas designated for tours, which the BK TYPE 20 unit reliably ensures.

Z-10 Nuclear Shelter: A Place with a Story

The Z-10 shelter, located deep beneath Špilberk Castle, is an intriguing place in its own right. It was prepared to shelter Brno's elite in the event of a nuclear conflict, and its interior conceals a range of period technologies, including the original filtration and ventilation systems.

It is a great honor for us to be part of ensuring the operation of such an important historical monument. Our system helps ensure that future generations will be able to safely explore and learn from the history that the Z-10 shelter preserves.
