John Cockerill is deploying a custom solution for treating exhaust gases from battery testing

With the rapid development of electric mobility, safety and emission control during battery testing are becoming major issues.

In this context, John Cockerill has designed and installed a specific system for treating the gases generated during combustion tests on electric vehicle batteries.

The objective was clear: to control pollutant emissions, guarantee the safety of the facilities, and meet environmental requirements, while offering a flexible, modular, and easily deployable system capable of adapting to one-off tests.

The system implemented by the John Cockerill EE teams is based on a complete and robust technical solution from the Ayra™ range, which includes:

• A stainless steel containment hood, designed to capture fumes at the point of emission,
• A network of stainless steel ducts, ensuring the safe transfer of gases,
• A Hastelloy C22 quench, which cools hot fumes immediately after capture,
• An AyraScrub™ caustic gas scrubber, neutralizing acidic or irritating compounds,
• A high-performance AyraVent™ extraction fan, ensuring the required airflow,
• A 12-meter-high stack for elevated dispersion of treated gases,
• An access platform designed to facilitate emission measurements at the stack, maintenance operations on the separator, nozzles, and the pressure sensor at the scrubber outlet.
