Introduction
KOCOVERK Airport System offers pre-conditioned air (PCA) units designed to provide efficient and environmentally friendly solutions for aircraft on the ground. These systems eliminate the need for aircraft auxiliary power units (APUs) and diesel-powered air conditioning vans, significantly reducing noise, pollution, and fuel consumption.

Environmental Impact
The KOCOVERK PCA system is all-electric, drastically reducing fuel consumption to nearly zero, thus minimizing environmental impact. For instance, a B-747 typically consumes 750 liters of fuel per hour, which the PCA system can reduce significantly.

Operation
The PCA units are user-friendly, featuring remote PLC controls that allow operators to select different modes easily. Positioned under the boarding bridge, they do not interfere with other ground support equipment. The simple control panel design enables operation by unskilled personnel.

Maintenance
The KOCOVERK ACC units require minimal maintenance due to fewer moving parts compared to diesel-powered alternatives. Key maintenance tasks include annual inspections of filter quality and refrigerant levels.

Advantages
The PCA system uses power calculations and PLC control to optimize air temperature and volume, enhancing passenger comfort. It eliminates the need for mechanical linkages and diesel engines, providing real air conditioning with dehumidified, cooled, and filtered air.

Installation
Designed for installation under passenger boarding bridges, the PCA units are ideal for retrofitting existing airports with minimal cost. They do not require large indoor spaces or extensive refrigerant piping.

Cooling and Heating
The PCA system can cool and heat aircraft year-round, reducing the need for separate diesel-driven heaters and improving the airport environment by lowering noise levels.

Technology
The PCA units feature Copeland Scroll compressors and environmentally friendly refrigerants like R 407 C and R 134 a. They include double evaporators and condensers for enhanced performance and reliability. Multiple compressors ensure minimal power consumption by operating only as needed.
