Quick and easy
The system is quick and easy to install in facades or ceilings, in new buildings or renovation projects. EVOST units arrive on site already mounted in the façade, ready to be connected to the main air and water network. No installation space is required in the room and no part is visible in the floor, walls or ceiling of the room.

Modular and compact
Its modularity opens up a wide range of architectural possibilities, allowing inexpensive modifications to be made. Its compactness means that it can fit into strategic locations and free up ceiling height.

The birth of a revolutionary product
EVOST was born of a meeting between a façade builder and an HVAC expert, both of whom believed in 2D construction and decided touse the façade as a global technical element capable of freeing up ceiling space.
The initial objective was to provide optimum thermal, acoustic and financial comfort, while allowing a great deal of architectural freedom and a reduced carbon footprint.
EVOST is Eurovent 2023 certified
Eurovent 2023
Since 1993, Eurovent Certita Certification has been recognised as a world leader in product performance certification in the fields of HVAC, air conditioning and refrigeration.

Why use EVOST?
![grande liberté architecturale Evost offre une grande liberté architecturale](https://www.leongrosse.fr/media/cache/resolve/m/marques/evost/evost-1-1.png)
Great architectural freedom
- Its compactness means it can be fitted into strategic locations and frees up ceiling height: gain the equivalent of 1 storey every 10 storeys .
- Evost offers you great flexibility of use and infinite possibilities for reorganising your space.
![confort optimisé Evost offre un confort thermique, acoustique et financier optimisé](https://www.leongrosse.fr/media/cache/resolve/m/marques/evost/evost-2-1.png)
Optimised comfort
- Thermal comfort: the temperature is uniform throughout the space, from floor to ceiling
- Acoustic comfort: its motorless technology enables it to achieve a Noise Rating of 35, in compliance with standard NF S31-080.
- Financial comfort :
- top-of-the-range product comparable in terms of investment to its competitors (chilled beam, fan coil unit, etc.)
- simple, cost-effective maintenance
- optimum energy consumption
- competitive overall cost
![réduit votre empreinte carbone Evost réduit votre empreinte carbone](https://www.leongrosse.fr/media/cache/resolve/m/marques/evost/evost-3-1.png)
A reduced carbon footprint
- On-board technology reduces the number of ducts and tubes required for the overall operation of the system, thereby reducing the system's carbon footprint.
- EVOST's design differs from fan coil or chilled ceiling systems in that it uses fewer materials and is less complex (no motors), resulting in a lower construction carbon footprint and easier recycling.
- The regulated system significantly reduces the overall energy consumed.
