The system removes moisture by taking air from
the crown area or cargo area and feeds it though
zonal dryer units between the cabin and the
outer skin of the aircraft using a specially
designed piccolo duct. This lowers the dew point
in the crown area preventing the condensation
process from occurring, thus keeping the
insulation blankets dry. Zonal Drying system is
standard equipment on the Boeing 787
"Dreamliner".
EasyJet already operates one of the industry’s
cleanest, youngest, most fuel efficient fleet
and the launch of the trial further demonstrates
the airline’s commitment to using the latest
technology to minimize the fleet’s environmental
impact. An EasyJet passenger’s carbon footprint
is already 22% less than a passenger on a
traditional airline flying on the same route and
aircraft.
The Zonal Drying system consists of a fan,
heater and a moisture absorbing, silica
impregnated rotor made of light-weight fiber
glass which will improve air quality onboard as
well as reduce water retention by channeling dry
air to the crown area of the aircraft.
With weight also being the key factor which
influences aircraft efficiency and fuel use, the
Zonal Drying unit’s use will contribute towards
reducing the airline’s £1.2 billion annual fuel
bill.
