Our approach

Your challenges

Energy consumption under scrutiny

Data centres are major consumers of electricity in Europe, with high PUEs driven by AI and the cloud. Regulatory obligations (CSRD, EU Taxonomy) require decarbonisation efforts and rigorous monitoring, under pressure from investors and regulators.

Cooling, the largest cost item

Server cooling accounts for up to 40% of energy costs. Increased density and high thermal loads require continuous optimisation without compromising availability.

Service continuity is essential

99.999% availability, Tier III/IV compliance and redundancy required: zero tolerance for failure, even during maintenance. Every operation must guarantee the integrity of the site.

Our projects

  • THERMAL MANAGEMENT OF SENSITIVE INFRASTRUCTURE

    US Nuclear Security data centre

    Critical cooling with 100% recirculated air and permanently controlled humidity, exceeding the strictest government requirements. Continuously purified air across the entire site: 99.99% of viruses and bacteria neutralised, 24/7, with no chemicals and no human intervention.

  • THERMAL MANAGEMENT OF SENSITIVE INFRASTRUCTURE

    Anonymous colocation data centre

    The l9Zl project is one of Air 2 O’s flagship projects, in Air 2 O’s SMR product category. This integrated solution, with a capacity of up to 422 kW, includes a water-side economiser/circulation coil and an economiser/DX trim.

  • THERMAL MANAGEMENT OF SENSITIVE INFRASTRUCTURE

    AXA & PRD – Rhenus Pharma

    The international group AXA and PRD, a major player in logistics and commercial real estate, called on Accenta to redesign the heating system of an 18,000 m² temperature-controlled warehouse located in Saint-Quentin-Fallavier.
