We reveal what lies out of sight.
AERYS SYSTEMS provides healthcare, industrial, catering, and commercial clients with instrumented diagnostics, specialized air system cleaning, and high-level technical advice on overall ventilation performance.
Bridging the gap between engineering rigor and commodity service.
AERYS SYSTEMS stems from a clear observation: air system maintenance is regularly treated as a simple commodity, carried out with no prior diagnostics or long-term vision.
By combining the analytical rigor of an Arts et Métiers engineer with technicians boasting over two decades of field experience, we bridge the gap between technical design and operational reality. We measure first, intervene with purpose, and document every result.
How the idea became a way of working.
An industry that acts without measuring
Air quality assessment, duct cleaning, equipment upkeep: services sold separately, rarely thought through as a whole.
Two skill sets, one company
Engineering training from Arts et Métiers, alongside experienced ventilation hygiene technicians. Precise measurement and practical skill, under one roof.
Measure, treat, document
No work without a prior survey. No job without a before-and-after record. You know exactly what was found and what was done.
Adapted to every environment
Healthcare and laboratories, commercial premises and the public sector, industry, catering. Four very different worlds, one standard of traceability.
Three objectives, never separated.
Every job, whether assessment or cleaning, serves all three at once.
Healthy buildings
Indoor air quality that is controlled, measured and documented, for the people inside as much as for sensitive processes.
Process safety
Critical systems and equipment cleaned and documented to the standards specific to each sector.
Energy performance
Clean installations that recover the airflow and efficiency they were designed for.
A network of two complementary locations.
