New air conditioning and purification system for the Last Supper

A strategic initiative for the protection of the work

Thanks to the interventions of Tea.co, the Refectory of the Leonardo da Vinci's Last Supper has been equipped with a new air conditioning and purification system, designed to preserve the masterpiece's integrity and improve the visitor experience.

“We also worked at night, slowly, to reduce vibrations during the works, respecting the schedule thanks to the fundamental collaboration of everyone, including that of the Dominican fathers” – he stated Chiara Rostagno, museum director.

A work that will stand the test of time

The new plants will introduce 10,000 cubic metres of clean air per day, constantly monitored by 90 sensors. This advanced system has made it possible to:

• Extending the life of the fresco of others 500 years, reducing wear and tear from pollutants and temperature fluctuations.

• Increase the number of daily visitors until 33%, decongesting the queues at the entrance and improving the user experience.

Technology in the service of conservation

Thanks to the interventions of Tea.co, The air inside the refectory now feels free of particulate matter and with a drastic reduction in nanoparticles – lower values of 90% compared to the outside air. This result was achieved thanks to the doubling of AHUs (Air Handling Units), which now work as a pair and can also operate autonomously in case of faults, ensuring operational continuity and safety.

Complementary interventions and engineering innovation

Beyond advanced dust filtration through new extraction systems, the engineers at Tea.co they have developed further improvement solutions, including environmental control and vibration reduction systems, to ensure the highest level of protection and comfort within the museum site.
