Swedish aircraft cabin humidity control specialist CTT Systems is hoping to place its zonal comfort system on SAS Airbus A330s and A340s as it pursues other opportunities for installing its system on the ultra-large A380 and cargo aircraft.

SAS has been testing a zonal comfort system on a Boeing 767-300ER since 2000. CTT president Torbjörn Johansson says: "We hope that in the next one or two months SAS will elect to put the system on its A330s and A340s."

The humidifying system is intended for first and business class cabins only, where cabin humidity can drop to 5% during long-haul flights. The humidifiers, mounted in the crown of the fuselage, raise the cabin humidity to a more comfortable 20-25%, and can be used in conjunction with CTT's zonal drying system to prevent moisture build-up on the fuselage skin.

Cargo carriers Cargolux and FedEx Express have both looked at the system for improving cargo area conditions for animal transport, he adds.
