CTT SYSTEMS AB (“CTT”), the market leader of aircraft humidity control systems, announces that an undisclosed airline has selected Inflight Humidification (IFH) in Business Class to be line-fitted in its entire Airbus A350-900 fleet. Aircraft delivery is scheduled from second half of 2019 to 2023.

The Inflight Humidification (IFH) system from CTT Systems is a highly appreciated feature in the VIP aircraft world. Powered by humidifiers onboard, the Business Class cabin environment is elevated to the same VIP-level with best wellbeing performance on the market. Business Class passengers will more easily stay hydrated, aiding better taste, improved quality of sleep as well as reduction of jetlag.  

A cabin climate optimized for wellbeing is all about replicating earth conditions. Modern widebody aircraft, such as the Boeing 787 and A350, have made great progress in lowering cabin altitude, reducing noise and vibrations, generating draft-free and fresher air, multiple temperature zones and advanced mode lightning. The level of humidity is the next cabin climate feature in order to improve the performance of the cabin and elevate the total cabin environment experience. Although basic configured A350 and Boeing 787 aircraft obtain a passive increase in humidity of 1-2 % RH, it is still far too dry – drier than any of the driest climates on earth. In a Business Class cabin, without a humidification system, air humidity is only 6-10 % RH. By selecting optional cabin humidifiers, available as SFE on both Airbus A350XWB and Boeing 777X, passengers can benefit from best cabin environment in the air.

“This is the second airline award this year for Inflight cabin Humidification in Business Class on A350-900. Further, two airlines this year have selected humidification for First/Business on Boeing 777X,” says Peter Landquist Vice President Sales & Marketing at CTT Systems. “Powered by our Inflight Humidification (IFH) system, an airline can take the Business Class experience to a higher level where passengers benefit from ‘True Wellbeing’, from better sleep, improved taste buds and senses, as well as from a more refreshing arrival.”
