CTT to show green credentials at emissions summit
Sweden’s CTT Systems will talk about the environmental merits of its cabin air drying system at the Emissions Trading and Aviation Summit (www.emissions-trading-aviation.com) in London next week.
CTT’s Zonal Drying System is designed to counter harmful condensation on the cold inside surface of the aircraft skin. Benefits include reduced fuel consumption and thus emissions through the elimination of significant weights of accumulated water, less corrective maintenance and thus improved operational reliability, and better insulation performance. Corrosion is also reduced, leading to an improvement in aircraft residual value. Zonal Drying has been selected as standard on the Boeing 787 and as an option on the Airbus A350.
Zonal Drying is complemented by the Cair humidification product. Cair humidifies the extremely dry air (3-5 per cent relative humidity) typical of first and business-class cabins without creating condensation. It is designed to provide a pleasant relative humidity of 25 per cent to reduce the incidence of problems associated with excessively dry air - fatigue, jetlag, red eyes, dry skin, airborne virus infections. The system is based on energy-efficient evaporative cooling technology and includes measures that effectively rule out the transfer of bacteria within the aircraft.
CTT humidification is optional in Boeing 787 crew rest compartments and on the flight deck; in the Airbus A350 cabin, flight deck and crew rest compartments; and in A380 crew rest compartments.
Recent major orders for Zonal Drying include one from Air New Zealand for installations in 13 Airbus A320s, 16 Boeing 737s, five 767s and eight 777s. The carrier expects to save 500,000 US gallons of fuel a year across the 42 aircraft, reducing carbon emissions by 4,700 tonnes a year.
