PCA

Cavotec has led the development of aircraft ground cooling systems for five decades.

Cavotec is the only supplier of fully integrated PCA systems and the broadest offering with either Point of Use (DX PCA) or Central system (AHU or DX-Boost) and in full compliance with IATA AHM974 and AHM997. All electrical, fixed or mobile, Cavotec PCA improve the airport environmental footprint.

Cavotec PCAir system was the world’s first approved AHM997 installation in 2009 at Bahrain International Airport.

Our 8,500 PCA worldwide installed base ensures aircraft APUs up to the Airbus A380 can be switched off under the harshest ambient conditions such as in the Middle East or South East Asia. We design and engineer our PCA systems based on the most challenging industry standards including the ASHRAE and AHM.

We optimise the entire system design including power requirement and air distribution flow and temperature from the PCA outlet up to the aircraft PCA inlets. Our engineering guarantees the we meet each single aircraft cooling requirement. Cavotec unrivalled PCA in-ground pits systems boost the overall system performance and ensure a better passenger comfort on-board the aircraft.

PoU DX PCA

Series PDX - Self-contained fixed or mobile electrical air handlers with vapour cycle direct expansion. Ranging from 30T to 120T DX PCA as per AHM974. Designed for cooling up to A380 under the Middle East ambient conditions with multiple cooling stages of compressors.

Central AHU

Series PAC – Light-weight air handlers connected to a central chilled water plant with 1 or 2 water circuits (EGW or CW+EGW). Designed as per AHM974 in ratings from 30T to 90T to service a full range of aircraft from narrow body through the new A380 configuration.

Central DX Boost PCA

Series PAC DX Boost – Hybrid Air handler with 2 cooling stages (water circuit with central chilled water plant and vapour cycle direct expansion). Designed as per AHM974 in ratings from 30T to 90T to service a full range of aircraft from narrow body through the A380 configuration.

Central Subfreezing DX Boost PCA

Series PAC DX Boost Sub-Z – Hybrid Air handler with 3 to 4 cooling stages (water circuit with central chilled water plant and vapour cycle direct expansion). Designed as per AHM997 in ratings to service a full range of aircraft from narrow body through the A380 configuration with a minimum discharge temperature of -25°C (-13°F).

Central Subfreezing PCAir

Series Pre-compressed Air – Brayton cycle with expanded pre-compressed air system generated from a central compressed air central room and distributed to PCA expanders. Designed as per AHM997 and with less than 1.7g water/kg dry air and in ratings to service a full range of aircraft from narrow body through the A380 configuration with a minimum discharge temperature of -25°C (-13°F).

PCA In-ground Pits

In-ground PCA Pop-up & Hatch pit systems serve as user friendly storage device for pre-conditioned air hose (up to 2) and other facilities, such as potable water supply. Located very close to the aircraft inlets, they are the optimum solution for reducing the cooling losses and pressure drops ensuring a faster aircraft pull-down.

PCA hoses and connectors

We build customised designs for PCA hoses and connectors available in multiple configurations and materials according to the selected PCA Ground Connection system in which they are integrated (E.g. Manual or motorised PCA hose reels, PCA in-ground pits). Including in this range the Sub-freezing PCA hose and connector as per AHM997.
