400Hz Ground Power Units (GPU) & Pre-Conditioned Air (PCA) installations at Al Maktoum International Airport (DWC)

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.

Dubai World Central is the most audacious aviation bet on the planet — a greenfield mega-airport being rebuilt to swallow 260 million passengers a year and replace DXB entirely. Launched in 2010 as a cargo and low-cost node, it is now the site of a USD 35 billion reimagination announced in 2024, sized for five parallel runways and over 400 gates. When complete, it will be the single largest airport the world has ever built.
