CTT Systems of Nyköping, Sweden, recently scored two large-scale orders for its CTT Cair cabin air system, one for a Boeing 747-8 being outfitted by Lufthansa Technik in Hamburg, Germany, and the other for an Airbus ACJ319 to be completed by Amac Aerospace of Basel, Switzerland.

It is the sixth Cair package to be installed by Lufthansa in executive versions of single- and twin-aisle airliners. The A319 represents the fourth Cair system to be installed by Amac.

The Cair system is based on evaporative cooling technology and the dual-purpose design precludes the transfer of bacteria in the aircraft and increases humidity for greater comfort. It includes CTT’s Zonal Drying system to counter condensation problems.
