Smoke extraction engineering

EOLIOS helps to protect communities, businesses and assets by helping its customers to better understand the risks of fire outbreaks and human behavior in the event of a fire. We perform smoke control simulations and advanced risk analysis.

EOLIOS is a design office specializing in fire risk engineering

At EOLIOS, we always strive to analyze, test and develop the best fire safety engineering techniques to protect a diverse range of built environments.

Our expertise and knowledge of risk engineering, combined with our smoke extraction engineering services, enable us to provide complete and safe fire safety engineering (FSE ) solutions, from initial designs through to construction, testing and commissioning, and beyond to final delivery.

Our specific smoke control engineering solutions

Our design office specializes in advanced design and consulting services in fire engineering and fire safety engineering.

Smoke control engineering services

Grâce à our Using specialized CFD modeling and analysis tools, EOLIOS analyzes and simulates the behavior and performance of systems and prototypes, with the aim of improving their efficiency and quality. Our simulations offer an accuracy and flexibility that cannot be achieved by other methods.

We help our customers not only to test their processes, but also to evaluate their performance and identify areas for improvement. In addition, simulation allows companies to multiply the tests of processes with different parameters and configurations, which allows a greater understanding and control of their processes.

EOLIOS engineers, experts in their respective fields, are ready to develop your systems.
