Why choose PCA
PCA Advantage
Pre-conditioned Air Unit (PCA) is a specialized air conditioning device on the ground designed to provide fresh air that has been filtered, pressurized, dehumidified and cooled (or heated) for aircraft cabins parked on the ground. These devices provide a comfortable cabin environment for passengers and crew members from the time the aircraft docks at the boarding bridge to the time it leaves the bridge.
Comparison of APU and PCA
Auxiliary Power Units (APUs) are small onboard engines that supply power and air conditioning when main engines are off, but they are noisy, fuel-intensive, high-emission and costly to maintain. In contrast, Pre-Conditioned Air (PCA) units provide a ground-based alternative with efficient cooling, lower noise, zero emissions and reduced costs.
