Sweden’s CTT Systems will provide Cair zonal drying equipment for two VIP Boeing 747-8s. The first is for a head-of-state Boeing 747-8 being completed by L-3 Platform Integration in Waco, Texas. The second is under a contract with Amac Aerospace of Switzerland. Both installations will be performed next year. The Cair system offers 20-percent humidified cabin air without creating condensation. The use of evaporative-cooling technology is also claimed to preclude the transfer of bacteria within the aircraft.
