EA-ACU-45 — Mobile Hybrid Air Conditioning Unit (PCA)
Mobile hybrid pre-conditioned air unit providing aircraft cabin cooling and climate control at remote stands where fixed PCA infrastructure is unavailable.
The EA-ACU-45 is ElectroAir's mobile hybrid pre-conditioned air unit — the portable counterpart to the fixed under-bridge EA-PCA series, designed for remote stand operations and airports where fixed PCA pit systems have not yet been installed. In the ground servicing sequence, PCA is the environmental counterpart to the GPU: where the GPU replaces APU-provided electrical power, the PCA unit replaces APU-driven air conditioning, allowing the APU to remain off (or be shut down early) during turnaround. This reduces fuel burn, noise, and emissions at the gate. The mobile form factor means the EA-ACU-45 can be deployed wherever an aircraft parks — including remote stands, cargo aprons, and temporary gates — without fixed infrastructure commitment. The hybrid designation indicates it can operate from an on-board diesel engine for full apron independence, or from an electrical shore connection when fixed power is available, enabling zero-emission hangar or enclosed-terminal operation. Compatible with multiple commercial aircraft types, it provides both cabin cooling and dehumidification — the dehumidification function is particularly relevant in Gulf operations where high ambient humidity at the aircraft door can cause moisture ingress into the cabin during ground holds. For procurement engineers, the EA-ACU-45 is the appropriate specification for airlines or handlers operating a mix of fixed-infrastructure contact stands and mobile-equipment remote aprons, where a single mobile unit covers both environments.
