Anhydrous Room

The manufacture of electric vehicle batteries involves handling highly hazardous and explosive materials, particularly during the production of powders or electrolytes. To ensure you have a workspace that is both efficient and safe, Equans supports you in the design and construction of anhydrous rooms, in compliance with health and safety standards. These specialized rooms require a very high level of technical expertise to ensure the enclosure is completely airtight. In this enclosed and completely airtight space, the atmosphere is continuously monitored to verify various environmental criteria: humidity, temperature, etc.

Ensuring the Integrity of the Atmosphere

Even a single deviation can damage the equipment or cause explosive particles to disperse if the humidity level is too high. Equipped with specialized air filtration systems, our anhydrous rooms maintain a humidity level close to 0, with uniform airflow throughout the entire room.

Early in the project, Equans teams work with the client to determine the optimal size of the cleanroom—tailored as closely as possible to their requirements—to optimize energy costs. To ensure precise control of the atmosphere, they also gain a detailed understanding of the client’s needs by assessing the thermal load of the equipment and the number of people likely to work inside the enclosure. This customized approach allows for a precise evaluation of humidity levels. This ensures the integrity of the atmosphere is maintained in accordance with your specific operations.
