In the aeronautics industry, hangars and workshops are often faced with major thermal challenges, particularly during the summer months. High temperatures can affect the performance of technicians, the quality of sensitive materials and the smooth running of equipment. OberA offers mobile adiabatic cooling solutions designed to meet the specific requirements of this sector.
Sommaire
Why opt for an air cooler in the aeronautics industry?
Thermal challenges in aircraft hangars and workshops
Aeronautical infrastructures such as hangars, maintenance workshops and assembly areas are often characterized by very large volumes, high ceilings and limited or non-existent thermal insulation.
Prolonged exposure to the sun quickly transforms these spaces into veritable “hotboxes”. In summer, temperatures of over 35°C are not uncommon indoors, with many negative consequences:
Traditional air-conditioning systems, which are expensive and energy-hungry, are often unsuited to these open environments, where doors are frequently left open for aircraft entering and leaving. This makes them virtually ineffective.
Impact of temperatures on equipment, materials and technicians
Excessive heat can lead to :
- Damage to sensitive materials: some composites, alloys and technical adhesives used in aircraft construction and maintenance lose their mechanical properties under the effect of heat. This can compromise the quality of assemblies, necessitating costly rework;
- Precision equipment malfunctions: measuring instruments or test benches can have their tolerances disrupted, reducing the reliability of quality controls;
- A significant drop in human productivity: above 28°C, there is a reduction in concentration, an increase in fatigue, and greater risk of malaise among operators. This translates into a drop in work rate, an increase in technical errors and higher absenteeism;
- Increased risk of incidents: in environments where rigor and safety are essential, every drop in vigilance due to heat can have major consequences.
Adiabatic coolers: a suitable, cost-effective solution
Faced with these challenges, mobile adiabatic air coolers by OberA are the ideal alternative. By using the natural principle of water evaporation to cool the air, they effectively reduce ambient temperatures, even in very open spaces.
Unlike closed air-conditioning systems, coolers operate with the door open, with no loss of efficiency and up to 5 times lower energy consumption.
A word from the expert: unlike conventional air-conditioning systems, our air fresheners are compatible with wide-open rooms. Better still, bringing in new warm air will boost the unit’s performance by converting it into cool air (3 to 12°C cooler than the outside air temperature).
How air coolers work in industrial environments
Principle of evaporative cooling (adiabatic)
The adiabatic system uses water evaporation to lower air temperature naturally. Warm air is drawn through humidified panels, causing the water to evaporate and cooling the supply air. This natural process is efficient, economical and environmentally friendly, without the use of refrigerant gases.
Comparison of fixed and mobile systems for the aerospace industry
The choice between a mobile or fixed air cooler depends closely on the configuration of your facilities, your usage constraints and the level of flexibility required. OberA offers solutions based on adiabatic technology to guarantee high-performance, cost-effective cooling without the need for a traditional air-conditioning system: mobile systems. Flexible and easy to move, they enable targeted cooling according to the specific needs of work areas.
OberA tip: for a large maintenance hangar with fixed activity zones, a fixed system is optimal. On the other hand, for modular workshops or seasonal requirements, the mobile cooler offers a fast, efficient and cost-effective response. In fact, most of our aerospace customers combine the two approaches.
Advantages of air coolers for aeronautics
- Efficient cooling for large open spaces: IC OberA range coolers offer air flow rates of up to 30,000 m³/h, enabling efficient cooling of areas of up to 400 m²;
- Improved working conditions for technical teams: by maintaining comfortable ambient temperatures, these systems reduce heat stress, improve technicians’ concentration and increase overall productivity;
- Lower energy costs compared with conventional air-conditioning systems: adiabatic coolers consume up to 80% less energy than conventional air-conditioning systems, offering substantial savings on operating costs.
Aeronautics: our tips for selecting the right air cooler
Choosing the right adiabatic cooler involves much more than comparing air flow rates and prices. In a sector as demanding as aeronautics, where working conditions, space configuration and technical constraints vary from site to site, it’s essential to select the right equipment.
Our OberA technicians, specialized in complex industrial environments, will help you assess your needs and propose the most efficient, sustainable and cost-effective solution. Here are the essential criteria they systematically take into account during on-site diagnostics:
- Power and air flow capacity: the larger the volume to be treated, the higher the flow rate (expressed in m³/h). For example, a 1,000 m² hangar with a height of 10 m requires a professional cooler capable of mixing several tens of thousands of m³/h.
- Mobility and flexibility: if your workshops evolve, or if certain areas need to be cooled from time to time (paint zone, final inspection, etc.), a mobile model with reinforced castors enables you to meet your operational needs without interrupting production.
- Robustness and durability: in an environment subject to dust, chemicals or mechanical shocks, choose a professional product designed with a reinforced structure, protected motors and ventilation adapted to harsh conditions.
- Type of water supply: some models have a built-in reservoir, others can be connected directly to the mains. This criterion impacts operating autonomy and maintenance frequency.
- Easy maintenance:quick access to filters, pump and water tank ensures easy maintenance, essential for constant, hygienic cooling, especially during intensive use.
Good to know: all OberA coolers are designed to operate in operate in demanding industrial environments. The IC range is particularly popular in the aerospace industry for its reliability, power and ease of use, even in mobile mode.
