What are the features of IC adiabatic air coolers?
The IC series represents our mobile evaporative air coolers. The IC 12, 22 and 30 coolers with 3 speeds allow you to cool small and large areas ranging from 150 to 400 m². With low water and electricity consumption, our IC air coolers represent a more economical and environmentally friendly alternative to conventional air conditioning.
Our three IC devices are equipped with a control panel and remote control to manage the programme and temperature. IC adiabatic air coolers are low noise, ranging from 54 to 77 decibels, which is equivalent to the noise level of a vacuum cleaner (76 dB). Each device is also equipped with a UV lamp that allows the water in the tank to be sterilised.
What are the advantages of the IC series?
Adiabatic air coolers use a natural principle known for centuries: evaporation, a simple, effective, economical and ecological technology. By sucking in ambient air and blowing out fresh air, the devices ensure that the air in the room or room is refreshed.
Adiabatic air coolers, which require only very little water and electricity, consume up to 80 per cent less energy than refrigerant air conditioning. The coolers do not require any installation.
Thanks to its automation, maximum water valve and minimum water level detector, there is no need to monitor the water supply level of stationary adiabatic air coolers.

How do IC series evaporative air coolers work?
The heart of the cooling system lies in the honeycomb panels, which are continuously supplied with water. An axial propeller fan located behind the adiabatic air cooler draws warm air through the unit. As the air passes through the cooling panels, the hot air vaporises the water. This phenomenon, known as the cooling effect, is achieved by evaporating water using the energy drawn from the air passing through it. This allows cooler air to be expelled from the appliance, with a drop in temperature of approximately 10 to 20°C.
For what uses?
IC adiabatic coolers are designed for use in industry to relieve workers from a large heat source (furnace, oven, hot air wave, etc.). All industries can use these devices to cool a room or a workstation. It is very important that the room to be cooled is ventilated to remove moisture and provide warm, dry air ready for cooling.

Its empty weight is 110 kg.
Do evaporative coolers increase the risk of infections and other health problems ?
No, quite the opposite! This question is commonly based on the incorrect assumption that evaporative coolers may cause a slight increase in humidity, but also increase the risk of viral, bacterial and fungal growth. All OberA evaporative coolers are equipped with pre-filters and a UV lamp which treat the air to remove particles that facilitate the movement of viruses and bacteria.
The positive effects of using evaporation are in fact well established. Not only does evaporative cooling provide clean, fresh, filtered air, it also consumes significantly less energy and is easier to maintain. It does not require the use of harmful CFC gases – unlike many air conditioners.
I work with steel products, so I don’t want humidity in my work environment as I want to avoid any risk of corrosion. Does this mean I can’t use evaporative cooling ?
Do our coolers evaporate water ? No The water in the cooler is in the form of vapor, not liquid (micro-droplets). Humidity will increase between 2% and 5%, depending on the environment.
There are some things you can do to avoid an increase in humidity in your environment.
Increase ventilation(open doors and windows). More ventilation means less humidity. The more ventilation there is, the less humidity will increase
Monitor the temperature and humidityto keep it at the right level at all times. Our evaporative coolers feature a built-in control panel to set the level.
Portable coolers are usually used to cool down a specific area. This means that only a part of the total area will be cooled down. Therefore, the total humidity effect will usually be much lower than 2-5%. Keep in mind that powerful evaporative coolers actually expel warm, moist air from the building.
Does evaporative cooling increase the risk of Legionella because it uses water ?
Legionella is a bacterium that grows in hot water systems. Our units are equipped with UV lamps. 100% of the water flowing on the cooling panels is treated by UV.
Moreover, legionellosis is transmitted by inhaling water aerosol contaminated by legionella bacteria. Our devices do not release aerosols. Water is vaporized or transported in the form of steam, not liquid.
The risk is therefore extremely low and is no greater than with conventional air conditioning.
Can I reduce the noise level of an evaporative air cooler ?
The noise levels of our units are generally below the existing noise levelin our main markets (industry, logistics, production) Moreover, the importance of the cooling effect far exceeds that of the sound reduction. Our coolers are equipped with a speed control so you can reduce the speed and thus the sound, if necessary. The smaller the cooler, the lower the sound level. The sound level of our units is 66 dB.
What can I do to adjust the airflow ?
Similarly to the sound-related question 4, some people in a factory may find the airflow disturbing. In this case, you can move the unit further away or adjust the direction of the flow. Our air coolers have adjustable flaps, which allow you to control the direction of the air flow. You can also adjust the speed with the control panel and lower the unit’s air flow.
Another solution is to place the cooler at a higher location to avoid directing the air towards people (the cool air always moves downwards, so this solution also guarantees proper cooling).
Why bother spending money on comfort – it’s cheaper to do without, right ?
Installation, operating and overall ownership costs are actually quite low, so evaporative cooling is sound financially. Additionally, employees working in hot environments are exposed to heat stress, which can affect both their safety and productivity. Working in a comfortable environment will improve their concentration and ability to work efficiently.
How do I clean my air cooler and store it at the end of the hot season ?
If your work environment is dusty or dirty, you should increase the number of times you clean and drain your cooler. We recommend emptying the water tank once a month when in use and cleaning it with clean water.
Prepping the air coolers for winter at the end of the season
The panels do not need to be changed if they are stored dry at the end of the season.
We recommend doing the following at the end of each season before storing the evaporative coolers for winter :
- Drain the units
- Rinse them with clean water.
- Run the appliances with clean water and add white vinegar if needed.
- Drain them completely
- Run them for at least 6 hours without water to dry the panels and the unit
