Exhibit of the Month – October 2025. Ammonia scrubbers – a modern path to cleaner air and a testament to the resilience of engineering

We are talking about ammonia scrubbers – technological devices that effectively purified gas from ammonia, becoming a symbol of modernity in their time.

The fate of this device is not only a story about technology, but also about war, destruction and post-war reconstruction. It is also proof of the determination of people who believed that even in the most difficult conditions, it was worth preserving what constituted the foundation of the city's development.

Why did it survive? What role did it play in the life of the capital, and what does it tell us today about the era in which it was created?

The film reveals the behind-the-scenes history that did not make it into the textbooks. It is a story about a device that survived the war, reconstruction and transformation of the capital. See for yourself how steel and wood can become a symbol of resilience.

We invite you to the MGW!
