400Hz Ground Power Units (GPU) & Pre-Conditioned Air (PCA) installations at King Abdulaziz International Airport (JED)

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.

Jeddah is the gateway to Makkah — and few airports carry such spiritual and logistical weight in a single footprint. Its Hajj Terminal, a Skidmore Owings & Merrill marvel of tented fibreglass, has moved pilgrims for four decades while the new Terminal 1 by HOK now handles Saudia's widebody flows. 2024 traffic climbed to 49.1 million as the Kingdom chases a goal of 150 million pilgrims and tourists a year by 2030.
