PCA Ducting-System
AIRPORTS are having a tremendous ENVIRONMENTAL IMPACT worldwide. The world’s climate is grievously harmed by noise and exhaust gases which could easily be avoided using the technology available today. On airports without a PCA Ducting-System, aircrafts get the energy from their own auxiliary turbines (AHU) or a GPU (Ground Power Unit). It is unfortunate that in most airports, aircrafts do not shut off their auxiliary turbines and spew out large amounts of unfiltered kerosene gas into the environment although with 600 litre of kerosene energy conversion efficiency is a mere 10%.
With a PCA Ducting-System, such unhealthy emissions are prevented.
The problem is caused by a lack of PCA units in most international airports. Only 8 PCA-systems are currently installed in European airports.
What is a PCA Ducting-System?
PCA stands for Pre-Conditioned Air. In other words, it represents a based air-conditioning system. The connection between Airport AIC and Plane is the PCA Ducting-System.
One Man Operation
The system is available very quickly and one of the most important advantages after completed work is that the hose may be easily stowed by one person in less than 2 minutes.
Why to Choose the PCA Ducting-System instead of a Flat Hose?
The biggest problem in southern countries is heat caused by extensive sunshine. Therefore it is essential that the chill generated cold air is being transported without getting heated - too much on its way from the air conditioning unit to the aircraft. This is a big loss in energy.
SHP Hose-Containers allow to store the PCA Hoses protected in a white heat reflecting box. Not more hose is taken from the container than necessary to connect with the aircraft.
The rest of the hose remains in the container and is thus protected against sun attack and potential rain as well as sand dust. While the hose is not used it remains protected against heat and rain in the container, which is positioned stationary under the boarding bridge. A flat hose, on the other hand, would be attacked by weather in its full length, also if it left unused in the basket. From the hygienic point of view, wire-supported hoses will dry during storage inside the container, while flat hoses will not dry.
Flat hoses will be considerably heated up in the open basket, and the cold air from the air conditioning unit has to cool the hot hose first before any cold air reaches the aircraft.Beside that, sand dust and other dirt particles can get into the adapter and from there inside the aircraft, contaminating the inner piping and filter system. Consequently, we favour wire supported insulated hoses stored and protected in a heatreflecting container.
