Sweden’s CTT Systems has been selected to provide its Cair cabin humidification system for two Airbus Corporate Jets (ACJs) that are to be outfitted in Toulouse. The order brings to five the number of Cair systems supplied for ACJs, with the two latest orders scheduled for delivery next spring for installation in two VIP A319s.Cair provides a humidity level of around 25 percent, a significant improvement over typical airline cabin humidity levels, which are 3 to 5 percent and contribute to many of the uncomfortable symptoms of air travel while also increasing the spread of viral diseases.

The system uses evaporative cooling technology and incorporates a means of restricting the movement of bacteria. It also includes the company’s Zonal Drying System, which counters condensation problems. This element has been selected as basic equipment in the Boeing 787, while humidifiers are options for the flightdeck and crew rest compartment. CTT humidifiers are optional equipment for the Airbus A350 and A380, while the full Cair system can be installed in the A350 as an option.
