Recent heatwaves highlight the need to maintain a cool environment in offices. However, installing a costly or complex air conditioning system is not always possible, especially in existing premises.
The air cooler then offers a natural and mobile solution to provide a breath of fresh air. Adapted to the needs of tertiary spaces, it helps meet new legal obligations regarding thermal comfort (Decree 2025-482 of May 27, 2025, imposing an adapted temperature in workplaces) while improving office well-being.
OberA’s evaporative air coolers from the IC range offer a simple, ecological, and mobile alternative to improve occupant well-being while controlling costs.

Why Install an Air Cooler in Your Offices?
During periods of high heat, professional premises can reach excessive temperatures. This directly affects employee well-being and productivity (a drop of about 20% in summer), and often, using fans is not enough.
A mobile air cooler creates a more pleasant climate by breaking the “battery effect” caused by heat. By slightly humidifying the air, it limits fatigue related to dryness and promotes concentration.
Installing such a device in the office thus helps maintain a comfortable and healthy work environment, even in hot weather.
The OberA IC Range: Modular Solutions for the Office
OberA offers the IC range, specifically designed for the tertiary sector. These models are discreet, efficient, and modular according to needs:
IC 12
Airflow 12,000 m³/h: ideal for small and medium spaces (individual offices, meeting rooms, reception areas). This ultra-compact model remains very easy to move thanks to its wheels; it is also particularly quiet and discreet.
IC 22
Airflow 22,000 m³/h: suitable for large open spaces (open-plan offices, company dining halls, libraries, reception lobbies). The IC 22 has a high-capacity tank and an integrated UV lamp, ensuring optimal water hygiene.
IC 12
Airflow 30,000 m³/h: designed for very large areas (vast open-plan offices, large break rooms, entrance halls). This high-flow model maximizes the cooling impact. It also includes a UV system and a generous tank for extended autonomy.
Each IC model is autonomous: they have a water level gauge and can be automatically supplied by a float. Users can thus “fill and forget” for several hours of operation.
Principle and Operation of Adiabatic Cooling
The air cooler uses a natural evaporation process to cool the air. Hot, dry air is drawn in and forced through humidified pads: heat is absorbed by the water, which completely evaporates, and the air exits cooler without aerosols. This simple principle, similar to the freshness of a body of water, requires no refrigerants, making its operation more environmentally friendly.
The cooler also slightly increases air humidity, which can improve the sensation of freshness in a dry office. However, like any evaporative solution, it is more effective in hot and dry climates; in humid regions, its effectiveness may be reduced.
Advantages of an Office Air Cooler
Choosing an air cooler for an office has more advantages than installing air conditioning or other costly solutions:
Energy Savings and Environment:
Compared to traditional air conditioning, an air cooler consumes up to 80% less energy. This significantly impacts electricity bills at the end of each month!
Furthermore, these systems do not emit any toxic refrigerants; the only “discharge” is water vapor, making it a very eco-responsible cooling solution.
Natural and Immediate Comfort
An air cooler delivers instant fresh air through evaporation. Users experience natural coolness, without the effect of dry cold. This passive cooling is even appreciated for indoor air quality, especially since some models include advanced filters.
Improved Air Quality
Most modern air coolers include purification systems. The OberA IC range, for example, features patented Pureflow pre-filtration, and even an integrated UV lamp that eliminates bacteria, viruses, fungi, and mold in the treatment water.
Result: the air blown is healthier, which is an advantage for open-plan offices and meeting rooms.
Mobility and Ease of Use
These devices are on wheels and very compact. Their lightweight design (anti-corrosion and anti-UV plastic chassis) allows them to be easily transported from room to room, even in old or temporary premises.
Moreover, they are Plug & Play: no major work or exhaust duct is required. Simply fill the water tank, plug in the device, and adjust the speed. Everything is designed for ease of use.
Quiet and Discreet
OberA range air coolers are designed to be quiet (45–63 dB depending on speed) and compact. They can therefore operate in an office without disturbing the work environment. Thus, they remain discreet while diffusing a large volume of fresh air.
Comfort and Productivity in the Tertiary Sector
In the tertiary industry, maintaining an adequate temperature is crucial for employee health and performance. Air that is too hot in an office can lead to fatigue, irritability, and decreased productivity. The air cooler helps preserve well-being in meeting rooms, open-plan offices, or reception areas where air conditioning is absent or insufficient. Furthermore, according to new regulations (Decree No. 2025-482), employers must ensure they provide an adapted work climate.
By providing a refreshing breeze and moderate humidity, these devices contribute to a healthy work environment that complies with standards.
Simplified Installation and Maintenance
One of the major assets of air coolers is their ease of installation. No heavy work or air distribution system is needed. Simply place the device in the area to be cooled, plug it into 230 V, and fill its tank. Then, choose the desired speed and air oscillation. The device is immediately operational.
Maintenance is also very minimal: it is limited to cleaning the humidified pads and refilling the water. For even greater convenience, OberA IC models offer automatic float filling and a washable Pureflow filter.
The 5-year warranty offered attests to their long-term reliability. Thanks to these features, maintenance remains minimal, which is a significant advantage for office building managers.
Ecology and Durability
Evaporative cooling is recognized for its low environmental impact. In addition to not using polluting gases, the device consumes very little.
This translates into reduced electricity bills, an important criterion for businesses. Furthermore, these devices are designed to last: reinforced chassis, reusable filters, and French manufacturing guarantee quality.
Usage Tips in Enclosed Spaces
It should be noted that the cooling effect of an evaporative device depends on the ventilation of the room. It is recommended to regularly ventilate the room to avoid humidity saturation.
In practice, a slight draft or periodic opening of windows is sufficient. Apart from this point, the air cooler adapts to most offices, even poorly insulated or modular ones.
