Pre Conditioned Air

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

DABICO 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-Hybrid) and in full compliance with IATA AHM974 and AHM997.

DABICO 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 can be switched off including the harshest ambient conditions such as in the Middle East or South East Asia.

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 the narrow body through the new A380 configuration.

Central DX-Hybrid PCA

Series DX-Arctic – 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.

Central Subfreezing DX-Hybrid PCA

Series DX-Arctic Sub-Z – Hybrid Air handler with 3 to 4 cooling stages. Designed as per AHM997 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 room, designed as per AHM997 with less than 1.7g water/kg dry air.

PCA In-ground Pits

In-ground PCA Pop-up & Hatch pit systems serve as user-friendly storage for pre-conditioned air hoses and other facilities, reducing cooling losses and pressure drops.

PCA hoses and connectors

Customised designs for PCA hoses and connectors available in multiple configurations and materials, including the Sub-freezing PCA hose and connector as per AHM997.

Key Benefits

‹

Low Maintenance Costs

System optimised for a lower PCA load reducing AHU and APU maintenance costs.

Approved Safety System

Best-in-class Sub-freezing PCA with an approved safety system as per IATA AHM997 interfacing with the Visual Docking Guiding System (VDGS) eliminating possible human error.

Faster Turnaround Time

Faster pull-down and cabin cooling time for a reduced aircraft Turn Around Time (TAT) and enhanced passenger satisfaction.

Collision Avoidance

PCA system designed for collision avoidance with Cavotec pit systems.

One-Stop Shop

Full turnkey system offer including PCA and in-ground pits.

Full Responsibility

Full design and performance responsibility from the PCA up to the aircraft inlet to meet specification requirements.

Versatility

PCA technology range is suitable for all aircraft categories (up to Code F, down to -25°C (-13°F) discharge temperature) and suitable for all ground handling operations in all climates.

Improved Cabin Comfort

Improved cabin comfort (with reduced humidity) for an enhanced passenger experience.

Minimum Cooling Loss

System engineering with PCA pits including hoses and connectors engineered for a minimum cooling loss and a reduced electricity bill.
