400Hz Ground Power Units (GPU) & Pre-Conditioned Air (PCA)
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.
"Gulf hubs are converting aircraft stands to fixed 400Hz and pre-conditioned air to cut APU burn in extreme heat — a major OpEx and Scope-1 lever at DXB, AUH, DOH and the Vision-2030 Saudi airports. Keeping a wide-body cabin habitable on a 48 °C apron without running the APU is a direct fuel, carbon and passenger-comfort win, and Liebherr and Guinault both market explicit hot-climate PCA-ACU lines. ElectroAir, a live AviationSouk pilot, builds exactly this GPU/400Hz/rectifier range for hot-climate apron deployment."

Why it matters in Gulf aviation
- APU-off in extreme heat: Gulf hubs are converting aircraft stands to fixed 400Hz and pre-conditioned air to cut APU burn — a major OpEx and Scope-1 lever at DXB, AUH, DOH and the Vision-2030 Saudi airports.
- Cabin habitability: keeping a wide-body cabin habitable on a 48 °C apron without running the APU is a direct fuel, carbon and passenger-comfort win.
- Bought as a pair: fixed 400Hz plus PCA at the bridge is a core decarbonisation package, so airports and PBB integrators procure power and air together.

Key evaluation criteria for Gulf procurement
- kVA and output type — match GPU rating and 28.5V/270V DC outputs to your fleet's electrical load.
- PCA cooling capacity and ambient design point — specify tons/kW and the ambient temperature the unit is rated to perform at, which is the binding constraint on a 48 °C apron.
- Fixed vs mobile — fixed bridge-mounted 400Hz/PCA cuts the most APU burn; mobile carts cover remote stands (often alongside apron buses and crew transport).
- Electrification fit — eGPUs and DC supplies tie into the wider GSE electrification and charging programme.
