Museums and archives: air treatment for optimal preservation of the pieces

Climate conditions and storage methods have a major impact on works’ and documents’ preservation. ETT air treatment systems with energy recovery give you control over temperature and humidity, for optimal conservation conditions.

As a museum director, a private archive manager, a maintenance technician in charge of national archives, …, you are certainly faced with the following issues:

  • Manage temperature and humidity for optimum conservation conditions: The excess temperature and humidity in buildings housing museums or archives can lead to the destruction of collections, editions, etc., phenomenon that can be very fast (a few days) in certain cases. The effects are visible: dry cracks, mold, bloom… When installing air treatment units, besides measuring the room temperature, it is important to measure the temperature on the surface of objects (books, paintings, sculptures) that can be higher by a few degrees due to the light sources. ETT is by your side to help you choose the air conditioning system with high-performance control and CO² probes that best fits your project.
  • Leverage energy consumption to reduce operating costs: air treatment represents 70 to 75% of your energy bill. To address current challenges and help you reduce your energy bill, our approach focuses on improving thermal efficiency while reducing operating costs.
