Thermal Comfort in All Your Spaces


In your living room, office, or your children’s school, this high-performance and environmentally friendly cooler ensures optimal comfort and preserved air quality.
Plus de questions ?We recommend hiring a professional (a certified heating engineer or plumber) to install one of our coolers. Installation takes only a few hours and requires a 230V power supply, a water supply (via a 6-8mm capillary tube), and two 160mm drillings on a facade wall.
Be sure to check beforehand if the device’s dimensions match the space available in your room.

Caeli One consumes 30W in Eco mode and 80W in Boost mode.
A Caeli One uses an average of 1 m³ of water over a full season of 4 months of continuous use. This clean water is released outside as vapor.
We are aware that water usage is an important issue and are doing everything we can to continue improving our performance. For comparison, a French person consumes an average of 54 m³ of water per year, water that is soiled and must be treated again.
We guarantee sanitary thermal comfort throughout the summer for the equivalent of about fifteen showers.
The real answer is… it depends! Indeed, temperature gains vary depending on the space configuration, insulation quality, exposure, and building location.
To give you a concrete example, in a 30 m² room located in a building with average insulation (neither a thermal sieve nor a passive house), the Eco mode is sufficient to maintain the comfort threshold set by the RE 2020 standard (26°C at night, 26-28°C during the day). For information, Caeli One produces air output into the room at an average of 16°C.
Caeli One has no external cooling unit, which means that the noise generated outside the building is very low.
Inside, Caeli One operates with 3 fans.
Caeli One is slightly noisier than a conventional air conditioner but remains perfectly suitable for daily use. However, we do not recommend installation in a bedroom.
No, Caeli One does not increase humidity. The air blown into the room never comes into contact with the water present in the system as it is an indirect system.
