CNDL provides a cooling rate improvement of 10-15%, together with a power saving when the PCAir equipment is installed directly beneath the PBB. MTO, meanwhile, significantly improves the airflow when the PCAir tools are evacuated in the terminal or on the apron.
MTO consists of two to three telescopic sections – depending on the length of the PBB – which are manufactured in stainless steel. The high-performance quality thermal insulation of MTO is achieved by special polyurethane foam isolation and a special rubber profile sealing. CNDL is an improvement of already existing storage systems for PCAir hoses. The flexible hose construction enables the compressed deposit of the hoses instead of furling them. This also allows extraction of the exact hose length needed according to each individual case or type of aircraft. “This way our system guarantees a sustainable and efficient energy and air supply for grounded aircraft, as the shorter the way the cooled air has to take, the less significant are the temperature and pressure losses when the air finally arrives at the aircraft and the less energy is needed for the cooling process. Especially for countries with high outside temperatures, this offers many environmental and economic benefits,” explained Jose Manuel Ardura, who is the responsible Engineering Manager at ThyssenKrupp Airport Systems.
London Heathrow was the first airport to install two prototypes of CNDL last summer, and has ordered a further 18 units.
Moreover, the system is very easy to operate as it has a low-weight aircraft connector with the operator panel located in the drive unit.
