Aircraft PCA unit

Aircraft PCA unit provides pre-conditioned air flow with required pressure and temperature to aircraft when docking at PPB.

 

Specifications and standards：

The product is designed according to international AHM standard and CAAC MH/T6109-2014 specification.

Working conditions：

Working conditions T1:Ambient dry-bulb temperture 35℃,relative humidity 50%.

Working conditions T2:Ambient dry-bulb temperture 35℃,relative humidity 60%.

Working conditions T3:Ambient dry-bulb temperture 35℃,relative humidity 70%.

Working conditions T4:Ambient dry-bulb temperture 35℃,relative humidity 80%.

 

Technology advantages:

Rapid Cooling.Output temperature at duct can be cooled to 3℃ within 3 minutes at cooling mode,which can satisfy time critical short-stop flights.

Ultra-low tenperture air supply.Airflow temperture at duct keeps under 2℃ during non-defrosting period.

By using intelligent defrosting fuzzy control method,defrosting interval is over one hour and defrosting period lasts about 4 min utes while the output temperture keeps under 5℃.

Wide range of working conditions.This is maybe the only machine in the market which can satisfy the requirements of all T1/T2/T3/T4 working conditions,with working temperture ranging -40℃～52℃ and relative humidity ranging 0～100%.

Capable of cooling all types of aircraft including Code-F A380 super jumbo.

Easy maintenance.By modular design,it is easy to repalce components.Components are interconvertible to different unit types which can minimize spareparts varieties.

Maintenance staff can download and install out APP to check the units' working status and receive fault alarms anytime,which will reduce invalid sitc inspections and maintenance coat.
