Air flow routing tubes are designed to channel different kinds of air to appropriate destinations. If you have a specialized vehicle and need superior flexibility in your air duct tubing, these products lead the industry. CARADUCT® flexible tubes are multi-layer, grooved tubes that are wound from a combination of aluminum and paper layers. They possess a particularly high crushing strength and have very good insulation properties. Through high flexibility and small bending radii, they offer good space usage, particularly when laying out in corners. Dükerrohr is a twin flexible tube distinguished by a particularly high insulation effectiveness to reduce temperature drops in the warm air ducting. Since it is installed outside of the vehicle, it carries additional protection against water and oil splashes.

The light weight and pliability of aluminum make it easy to work with and can streamline installation. In addition to the weight advantage and ductility, aluminum provides a complete barrier to light, moisture and magnetic waves. Impermeable to all gases including oxygen, aluminum also provides superior fireproofing capabilities for both industrial and residential construction. Aluminum insulation offers good noise reduction properties along with resistance to corrosion and heat. Not only does this improve interior environments, it also increases product life and efficiency. These proven characteristics continue to make aluminum the leader in insulation and the preferred choice for all types of building and construction.

Novelis is the global leader in rolled aluminum products and aluminum beverage can recycling. Our technical competence and innovation have made us a development partner chosen by leading companies from the automotive, building, printing and packaging industries, among others. With its customer orientation and strong industrial performance, Novelis plays a crucial part in shaping products for the future. The aluminium content means that there is only slight thermal length variation, just like with metal tubes. In addition, the tubes become completely oxygen-impermeable, which is indispensable when connecting radiators, for example. Using state-of-art production facilities and experienced specialists, Novelis ensures top quality in the manufacture of its products – across the entire production process, from casting and processing the ingots via hot and cold rolling, to packaging.
