THEY APPROUVE TEMPESTA
GSF Cleaning & Services
The GSF group has integrated Tempesta into its industrial cleaning operations at high thermal constraint sites such as:
- The Bugey Nuclear Power Plant (CNPE – EDF)
- The Tereos factory in Connantre (agri-food)
- The O-I glass factory in Béziers
- The O-I glass factory in Wingles
At these sites, GSF operators use Tempesta during confined space interventions, on rooftops, or near furnaces. Feedback highlights a significant reduction in hardship, immediate thermal comfort, and better recovery after exertion.
Compatibility with PPE, ease of use, and robustness of the device under intensive conditions have all been confirmed. These features make Tempesta a real driver of performance and quality of work life for field teams.
ArcelorMittal
As a global leader in the steel industry, ArcelorMittal was one of the first major industrial groups to deploy the Tempesta vest in the field.
The initial deployments took place at the Fos-sur-Mer site, a particularly demanding environment characterized by intense radiant heat, heavy protective gear, and high operational constraints.
Operators praised the thermal comfort provided and the stabilizing effect of the system during long shifts.
This structured use case validated the robustness of our solution under extreme conditions and initiated discussions around wider integration across the group’s industrial sites.
Municipal Police – Mandelieu-La Napoule
During a public event organized by the City of Mandelieu, two Municipal Police officers tested the Tempesta vest under intense summer conditions.
The feedback was positive: users reported an immediate cooling sensation, decent autonomy (~4h), and a direct impact on heat management during outdoor duties.
This experience confirmed the relevance of such a device for public safety missions in extreme heat.
When you choose Tempesta, you choose better working conditions and more efficient workers!
In many industrial environments, workers are exposed to extreme temperatures, whether in steel mills, nuclear power plants, glassworks or other industries. The Tempesta system from Tethys offers a revolutionary solution to ensure their thermal comfort and improve their working conditions.
Whether in metallurgy, power generation, glassworks or any other sector where working environments are very hot, choosing Tempesta means choosing improved working conditions and more efficient teams. Thanks to technology developed in the space and nuclear sectors, Tempesta represents a significant advance in worker well-being and safety.
Adopt Tempesta and transform your working environment into a space where comfort and efficiency go hand in hand.
| Sector | Critical Tasks | Thermal Risks | Tempesta’s Benefits |
|---|---|---|---|
| Construction | Concrete formwork in summer | Heat, fatigue, accidents | +15% efficiency, -20% incidents |
| Metallurgy | Foundry work | Thermal radiation | Fewer breaks, improved focus |
| Urban Logistics | Summer delivery rounds | Cab heat, fatigue | Enhanced comfort & alertness |
| Postal / Delivery | Walking / cycling deliveries | Prolonged effort in heat | Less fatigue, better recovery |
Short circuit
As part of our eco-responsible approach, Tempesta favors local and national suppliers to reduce the overall carbon footprint of our system.
Social inclusion
In 2026, Tethys plans to hire staff with disabilities. With Esatitude, it hopes to employ staff for a period of 6 to 9 months, during which they will have the opportunity to gain experience and skills.
