Air Distribution

Even at altitudes of over 10,000 metres, passengers must feel comfortable. The cabin air plays a key role in this. For decades, Diehl Aviation has been providing travellers with pleasant air pressure, sufficient oxygen and a comfortable temperature through its innovative solutions.

Air Distribution Air Distribution

Diehl Aviation is one of the world's leading system providers. Its expertise in systems, simulation and in-house testing enables it to deliver optimal technical solutions. The company advises aircraft manufacturers from the design phase of a new aircraft onwards, and has helped to develop air conditioning systems for the Airbus A350, for example, as a first supplier. The focus is always on achieving maximum functionality with minimum weight. Another notable feature is that Diehl Aviation's air conditioning systems are designed to prevent unpleasant noises caused by air draft, with specially designed geometry and silencers developed in-house. These features have made the company particularly successful, and it is no coincidence that Diehl Aviation is the market leader in its Air Distribution product group.

Diehl Aviation also supplies all the components needed for the air conditioning of aircraft of all sizes and types. The company also develops customised components that are perfectly tailored to the customer's needs upon request. If repairs or maintenance are required, Diehl Aviation experts are available to provide on-site support at numerous locations worldwide.

  • Mixing Unit

    Diehl Aviation's contribution lies in implementing the manufacturing technology, ensuring efficient and high-quality production and integration of the unit. This involves mixing hot air from the engines with cooled, filtered air from the air generation unit, before directing the treated air into the various cabin areas. The mixing unit can withstand very high and sub-zero temperatures, as well as ice build-up.

  • Special Channels and Panels

    Diehl Aviation also develops and manufactures specialised ducts to ensure that air is conveyed efficiently to the air generation unit. These components are designed to handle large air volumes, high pressure and high speeds. They are constructed using autoclave technology to provide exceptional stability, and are optimised for lightweight construction through the use of cutting-edge materials.
