Sweden’s Nova Airlines has ordered zonal drying systems from humidity control specialist CTT System for installation on three Airbus A321s. The contract calls for CTT to install the systems in the aircraft in April and May of this year.

Eliminating condensation lowers aircraft weight and therefore fuel burn, improves reliability due to the need for less corrective maintenance and aids insulation performance (water reduces insulation performance), the company said.

Boeing has selected the CTT system as basic equipment for the 787 Dreamliner and offers its humidifiers as options in the crew rest compartments and on the flight deck. Airbus has also chosen CTT to supply optional zonal drying systems and humidifiers on the A350XWB, and the Airbus A380 crew rest compartments can be fitted with CTT’s humidifiers as an option.
