CTT Systems AB (“CTT”), the market leader in aircraft humidity control systems, announces Zonal Drying™ retrofit order for 25 Airbus A319 aircraft from Eurowings (a subsidiary airline of the Lufthansa Group).

“By installing this weight-saving system, we will improve the fuel efficiency and lower the CO2 emissions of our A319 aircraft,” says Ivan Savov, Operational Excellence | Fuel Efficiency at Eurowings. We are pleased with the Zonal Drying system’s test results. During the 12 months trial in one of our A319 aircraft, we weighed the aircraft, which made it possible to measure and quantify the positive effect from the significant reduction of trapped condensate water.”  

“The Zonal Drying system’s efficiency is proven and the only way for airlines to actively prevent condensate water from accumulating in the aircraft fuselage,” says Peter Landquist, Vice President Sales & Marketing of CTT Systems. “The Eurowings trial confirms the value our system provides to airlines. At CTT, we are pleased to conclude that the Eurowings trial results have proven our methodology for estimating the amount of excess water in an aircraft."
