  • EOLIOS innovates in the industry

    New modeling techniques for the industry! EOLIOS provided its technical expertise in understanding and modeling heat and air exchanges in a plastic product production and assembly plant. This plant is characterized by numerous high temperature furnaces and different soaking tanks. The final temperatures in the building are extremely hard to estimate r without using the simulation tools we have developed. In the factory, the production part can lead [...]

  • External CFD simulation – Data center

    Latest News: Whether on the ground, on the roof or both, mechanical heat rejection systems such as cooling towers and chillers share space with back-up electrical generators (generator set). A compact high density layout inside the building results in a compact layout of the outdoor cooling equipment. This leads to significant challenges and problems in managing the airflow outside the building. Most manufacturer's equipment documents provide minimum clearance requirements [...]

  • CFD simulation – Data Center

    Latest News: Hello everyone, Today, we take a little time to present the external CFD studies for data centers, industries and other sensitive sites. What is it used for ? Well, in a context of high heat and high installation density, the roof dryers can interfere with each other leading to a significant loss of power, or even stop in cascade. This is not ideal for safety devices that [...]
