Pre-Conditioned Air Unit


Intelligent control

  • Automatic running regulation with independent cooling systems guarantees efficient operation under all-weather conditions at airports.
  • Automatic adjustment on air volume and pressure adapts to the requirements of different aircraft.
  • Intelligent defrosting operation performs automatically without switching operation mode.
  • Unique energy regulation technology ensures less discharge temperature fluctuation and more comfortable passenger experience.

Safety and reliability

  • Multiple independent cooling systems are mutually complementary.
  • Branded parts boast their long lifespan and reliable performance, adding extra advantages to PCA.
  • Various air volumes and pressures can be selected in accordance with different aircraft to ensure aircraft safety.
  • Safe and efficient operation of the PCA can be guaranteed by comprehensive protection measures, including air volume, air pressure, overheating, overpressure, smoke and filter pressure differential protection, etc.

Economical and energy-saving

  • Multi-step cooling ensures the highest efficiency of compressor operation, which means the PCA is economical and energy-saving.
  • Combined with parameters, unique defrosting technology ensures efficient long-time operation and a high energy efficiency ratio.
  • Compared with an APU cooling system, PCA can save over 80% in operation costs.

Friendly and convenient

  • Inspection door or maintenance board is mounted near to main parts for easy maintenance.
  • Three mounting methods are available, namely bridge-mounted ground-mounted and mobile, meeting with different requirements of airports.
  • Liquid crystal touch screen is chosen to realize friendly man-machine interaction.

Fast cooling

  • Multi-stage cooling system achieves low-temperature air supply with a large enthalpy difference.
  • Unique energy regulation technology effectively deals with all kinds of environments, ensuring rapid cooling and low-temperature air supply.

Environmentally friendly

  • R407c, R410A or R134a refrigerants are selected in response to global emission reduction.
  • Electrically-driven cooling reduces carbon emissions and protects the environment.

Remote monitor and control

  • Standard RS485 interface with Modbus RTU communication protocol.
  • Standard Ethernet interface with TCP/IP communication protocol.
  • IOT (Internet of Things) cloud platform enable real-time running state monitoring and remote diagnosis through mobile phone or computer.

Branded Parts

  • Core components are from Siemens, Danfoss, Schneider, and other international brands, facilitating global procurement.
