Dynae, a subsidiary of Clemessy, is a service company, the leader in France in the field of diagnoses on rotating machines. We carry out work on a daily basis on all types of industrial premises to examine production machines, detect symptoms of wear and tear or malfunction and recommend suitable remedies. Vibratory analyses, supplemented by electrical analyses and infrared thermography are our main tools of investigation. They allow us to diagnose the behaviour of the shaft line and its whole environment: the structure, the piping, as well as the site’s electrical equipment. Dynae also proposes training courses in these techniques. Our IT experts develop the measuring and processing software which is useful to the Dynae experts and our customers. The instrumentation department provides turnkey solutions for machine vibratory monitoring purposes.
