Efficient, low-emission air supply for modern airport operations.
Sustainable cabin cooling at airport gates with Pre-Conditioned Air (PCA)
Smarter cooling for aircraft on the ground
Airports worldwide are transitioning toward more sustainable and energy-efficient gate operations. A key part of this transformation is the use of pre-conditioned air units (PCA) to supply clean, temperature-controlled air directly to the aircraft cabin during turnaround.
By replacing the use of onboard auxiliary power units (APUs), PCA systems significantly reduce fuel consumption, emissions, and noise – while improving passenger comfort and working conditions on the apron.
Modern PCA solutions are designed to integrate seamlessly into airport infrastructure, supporting both new gate developments and retrofit projects.
PCA as part of an integrated gate solution
Today’s airport gates are no longer built around standalone units. Instead, they are evolving into integrated, intelligent systems, where PCA works in synergy with other ground support equipment such as GPUs and charging infrastructure.
By connecting equipment and managing power intelligently, airports can:
- Maximize the use of existing electrical infrastructure
- Avoid costly upgrades
- Balance energy demand across multiple units
- Support the transition to fully electrified gates
This system-based approach reflects a shift from individual products to holistic gate optimization, improving both efficiency and sustainability. We call this system approach 'EcoGate'.
Designed for modern airport operations
Pre-conditioned air units are engineered to meet the operational demands of today’s airports:
- Compatible with a wide range of aircraft types
- Suitable for both bridge-mounted, fixed, and mobile configurations
- Scalable for different gate layouts and traffic volumes
- Designed for reliable, continuous operation in demanding environments
Advanced PCA technologies also enable automated airflow adjustment and optimized performance based on real-time conditions, ensuring efficient operation without unnecessary energy use.
Solutions such as the ITW GSE 3500 PCA demonstrate how automation and intelligent control can further enhance airflow precision and energy efficiency — supporting airports in achieving their sustainability goals.
Supporting the transition to greener aviation
The aviation industry is under increasing pressure to reduce its environmental footprint. Electrification of ground support equipment, including PCA systems, is a proven and scalable way to achieve meaningful reductions.
ITW GSE supports this transition through a strong focus on clean-tech innovation and customer-driven solutions, contributing to reduced energy consumption and lower emissions across airport operations.
By implementing PCA as part of a broader gate strategy, airports can take a significant step toward:
- Meeting regulatory requirements
- Achieving carbon reduction targets
- Future-proofing their infrastructure
