MRO Hangar - Daxing International Airport, Beijing, China
SECTOR: Maintenance, Repair, and Overhaul (MRO)
LOCATION: Daxing International Airport, Beijing, China
The Beijing-Daxing International Airport is one of the most impressive airport infrastructures in the world, designed to alleviate air traffic congestion in the Chinese capital Located approximately 46 kilometers south of Tian’anmen Square, the airport spans a surface area of 700,000 m² and was inaugurated in September 2019. The passenger terminal, designed by Zaha Hadid Architects in collaboration with ADP Ingénierie, features a radial configuration with six arms extending from a central hub.
This innovative structure facilitates passenger flow and reduces travel times within the airport.
China Southern Airlines and GAMECO also inaugurated an aircraft maintenance hangar at Daxing Airport. With a surface area of nearly 40,000 m²—equivalent to about five football fields—it is the largest hangar in Asia. The hangar can simultaneously accommodate up to 12 aircraft:
- 2 Airbus A380 (the largest passenger aircraft in the world).
- 3 Boeing 777 (large wide-body aircraft).
- 7 narrow-body aircraft (smaller, narrower aircraft like the Airbus A320 or Boeing 737)
THE CHALLENGE
The construction of this impressive hangar posed numerous technical and operational challenges. The extraordinary dimensions of the structure—covering 390,000 m², with a span of 405 meters and a height of 40 meters—presented significant difficulties in achieving:
- Energy Efficiency: Ensuring a heating system capable of maintaining comfortable working conditions in such a vast space without excessive energy consumption
- Uniform Temperature Distribution: Reducing thermal stratification to ensure consistent heating where maintenance operations are performed
- Operational Flexibility: Installing a solution that seamlessly integrates with hangar operations without interfering with daily maintenance activities
Solution
To address these challenges, Impresind supplied its modular gas-fired radiant strip heaters, TUB-ONE, tailored to meet the specific needs of the Daxing hangar. The system was designed to provide an efficient solution to the critical challenges of this massive structure:
- Eliminating Thermal Stratification: With radiant heating technology, TUB-ONE ensures heat effectively reaches ground-level work areas, reducing energy waste caused by heat accumulating in the upper sections of the hangar.
- Enhancing Energy Efficiency: Radiant heat targets specific areas, minimizing energy consumption and reducing heating costs compared to conventional systems.
- Providing Scalable and Flexible Installations: The modular design of TUB-ONE allowed for strategic and customized placement throughout the hangar, ensuring optimal coverage without interfering with aircraft maintenance operations.
The installation of TUB-ONE at Daxing International Airport led to:
- Improved Operational Comfort: Uniform temperatures throughout the hangar created a safer and more productive environment for maintenance personnel.
- Significant Energy Savings: By eliminating thermal stratification and focusing heat where it’s needed, the system reduced energy costs by up to 30%.
- Enhanced Sustainability: Efficient energy usage aligns with China Southern Airlines’ commitment to environmentally responsible operations, setting a benchmark for sustainable practices in aviation MRO facilities.
ENGINEERING EXCELLENCE IN THE WORLD’S LARGEST HANGAR
The Daxing maintenance hangar is more than just a structure—it is a symbol of engineering innovation and sustainable design. With the installation of TUB-ONE, Impresind demonstrated its ability to deliver cutting-edge climate solutions for the most demanding environments.
