2011 – 2016: the first drafts

Aware of the ecological pollution caused by data centres, Nicolas Boulinguiez is looking closely at a solution.
He then installed an extractor in his server room to remove the hot air. Later and in a different location, he will test the combination of an adiabatic cooling solution and free cooling. He will go even further by testing the immersion of a computer in a liquid solution.

These successful trials will be the first green edge data centre…

2016 – 2021 : the era of development

In order to be able to implement its full-scale solution, it was necessary to find a suitable container for the integration of several servers. A rectangular stainless steel milk tank for example…

The tank was adapted to accommodate the submerged servers by a team in the garage of one of the employees.

This was the first official prototype – and at the time it was already able to recover 60% of the energy, equivalent to the heat output of a pellet stove.

2021 – 2022: the first production

Designed by us from scratch, the first demonstration model went into production. It will not escape a new performance test in the laboratory with an incredible result following technical adjustments: 90% of the heat is now recoverable. Our solution will be officially named HYPERION and presented at the Viva Tech international trade fair under the very interested eyes of Constance Nebbula (vice-president of the new Regional Council of Pays de la Loire) and the European deputy Valérie Hayer who came to meet us directly.

since 2022: the rise of hyperion

The deployment of the solution is intensifying, guided by the objective of acting quickly to green data centres on a large scale.
Our company is also following the trend and is moving to new premises to allow for the integration of new employees, and of course HYPERION is heating the sanitary facilities in these new premises!
