Aircraft Pre-Conditioned Air Unit

Shenling Pre-Conditioned Ar (PCA) Unit is an elaborately designed and manufactured product developed by Shenling. With years of experience in design and production. On the base similar products at home and abroad, the unit has been developed with the advantages of small size, high efficiency, lower noise, long life, and easy operation, which matches the requirements to run for full-day all year long.

Currently, the PCA unit has already been an essential airport ground facility. PCA unit is driven by electricity and works with a direct evaporating refrigeration cycle and air-cooling technology. it can replace the Auxiliary Power Unit (APU) of aircraft to provide fresh air and a comfortable environment with appropriate temperature and humidity to the aircraft cabin through an air hose. Compared with APU, PCA unit operation cost is 80% less with the same effect.

Besides, it can significantly reduce air pollution around airports. Thus, it is widely adopted by customers all over the world. Shenling is the first company to design PCA units according to new industry standards and successfully passes the quality and consistency test by authorized organizations in China. Shenling PCA unit has been successfully installed and used at Belling Capital International Airport, Kunming international airport, Changsha Huanghua International Airport, Chengdu Shuanglu International Airport, Chongqing Jiangbei International Airport, Guiyang Longdongbao International Airport, etc. Shenling PCA unit is highly complimented by the customers for its good and stable performance.

Energy Saving

Before launch or during maintenance, the aircraft needs power and compressed air for air conditioning in the cabin. But it costs a lot with the APU system by burning expensive aviation fuel. Besides, exhausted air emission, such as CO2 from fuel burning, causes pollution in the airport. Shenling PCA unit has passed the authorized organization test and obtained the qualification certificate from the Civil Aviation Administration of China. With higher energy efficiency and better performance, the Shenling PCA unit has reached the leading level.

According to basic calculation, for an aircraft with air conditioning supplied by APU, the fuel consumption per hour is 4.88 times of the Shenling PCA unit combined with the boarding bridge. Take the Shenling 60 USTR PCA unit as an example, it can save 214 tons of aviation fuel, which is equivalent to 314.9 tons of standard coal, compared with the APU System. Also, nearly 1200 tons of exhaust gas from aviation fuel burning when aircraft is on the ground, including CO2, NO, N20, and CO, can be reduced per year. lt means customers can be benefited from the Shenling PCA unit’s energy-saving and environmentally friendly features. The PCA unit can save much more energy than APU System. Aircraft air conditioning costs can be reduced before launch or during maintenance because it is not necessary to switch on APU System, a PCA unit can be used instead and this extends the APUS system service life.

Adaptable to different environments

Shenling PCA Unit, according to global climate characteristics in different regions, can be adapted to different special geographical environments such as high temperature and high humidity, low temperature, high altitude, and sandy, coastal salt spray corrosion, Please specify the application environment when ordering. The power supply is optional according to using kcations, 380V-50HZ, 380V-60HZ,400V-50-Z,400V-60HZ415V-50HZ, 460V-60HZ and etc. If a non-standard power supply is required, please specify when ordering Standard models’ operating temperature ranges from -20℃ to 50℃. Low-temperature models range from -40℃ to 50℃. They are applicable to environments of different regions. If there is a special applicable temperature requirement, please specify when ordering.

Various installation methods are available, including hanging type, floor-standing type, towed type, vehicle”mounted type and etc, It can be installed under the boarding bridge cr on the ground. For aircraft on the apron with distance, it can be mounted on a vehicle. Flexible installation can match different airports’ requirements.

Reliable

The high reliability represents various aspects of advanced technology, which is based on years experience of in air conditioner design and manufacture. Through optimized designs, PCA System has multiple functions of safety protection, troubleshooting, and alarm for safe operation.

Intelligent Control System

Shenling PCA unit can automatically and accurately adjust its cooling capacity according to temperature and thermal load required by the aircraft cabin to save energy. PCA unit electrical system is reliable. Programmable Logic Controller (PLC) is a globally famous brand with advanced technology. The control panel is made of imported LCD. The interface is friendly and easy to operate. Multiple safety protections have been set in the controller for safe and reliable operation. Pre-set standard RS485 communication interface allows remote monitoring, unmanned, and network controls.PCA unit can be equipped with a network accounting system developed by ShenlingThrough computer control, the total expense of air conditioning with 400Hz electric power can be displayed on the screen. It not only simplifies manual calculation but also records data and expenses automatically and objectively.
