400Hz Ground Power Units (GPU) & Pre-Conditioned Air (PCA) installations at Zayed International Airport (AUH)

This sub-category combines the two halves of the APU-off gate package. Ground Power Units supply electrical power to a parked aircraft: diesel-engine mobile GPUs, battery and hybrid eGPUs, fixed gate-mounted 400Hz solid-state frequency converters, 28.5V DC rectifiers and 270V DC supplies, plus gate boxes, load banks and heavy 400Hz/28V cabling. Pre-Conditioned Air delivers conditioned air to the cabin through a hose to replace the APU's environmental load: diesel and electric mobile PCA carts, fixed bridge-mounted PCA, and aircraft air-conditioning units (ACU) engineered for extreme ambient temperatures. Buyers specify by kVA rating, output type, cooling capacity (tons/kW) and ambient design point; fixed 400Hz plus PCA at the bridge is a core decarbonisation lever, so airports and PBB integrators procure both together.

Renamed in 2024 in honour of the UAE's founding father, Zayed International announced itself to the world with Terminal A — a sculptural, light-flooded building the size of 27 football pitches, opened the same year. Home to Etihad's Greenliner fleet, the airport is Abu Dhabi's statement that capital-of-culture ambitions demand capital-of-aviation infrastructure. Passenger volumes surged to 28.8 million in 2024 as Etihad accelerated a 170-aircraft fleet plan.
