Climatic and acoustic tests chambers

Thanks to our its partnership with ALSTOM, CEF has the opportunity to use tests benches to realize climatic and acoustic/vibratory tests.

 

 

 

Climatic chamber

This test mean was originally dedicated to type tests and to develop cooling or heating/ventilation equipment. It can also be used in other fields (electrical, road, aeronautics, military, etc.) to test under extreme conditions every large specimen.

          Acoustic chamber

 

This installation is made by a double reverberation chamber, designed for tests of acoustic transparency in diffuse field.

 

Vibratory analysis can also be realize with impacts hammers of adapted sizes.
