Each 787 will have two Zonal Drying units installed as standard and, in addition, three humidifiers are optional – one for the flight deck and one each for the flight crew and flight attendants' crew rest areas. CTT has been working in close association with Boeing since 2005, when it was awarded the contract. CTT has also appointed Satair as its worldwide partner, covering spares provisioning and repair.
CTT Systems AB President Torbjörn Johansson, commented: “It is a great privilege to be working so closely with Boeing on the 787 Dreamliner. CTT is proud to be part of an airplane that features an unrivalled passenger experience and superior efficiency in terms of fuel consumption.”
“Zonal Drying” eliminates condensation within the aircraft's fuselage resulting in improved operational reliability and consistent insulation performance. Meanwhile, the optional humidifiers in the flight deck and crew rest increase humidity to around 20 percent.
In addition to the Boeing 787 Dreamliner, the Airbus A380 offers CTT's humidifiers as an option in crew rest compartments and, already, the 'Cair' system is in-service in the First Class cabins of Lufthansa’s A380s. CTT will also supply the 'Zonal Drying' and 'Cair' systems as options for the Airbus A350.
