Sweden’s CTT Systems (W207) is optimistic about the prospects of its patented cabin air humidifying systems.
The company was recently selected for the Boeing 787 programme to supply zonal drying equipment which uses water from the hull lining to recycle through the cabin as raised humity.
Up to 40 litres (10 gal) per flight hour in condensation is removed from the hull lining.
CTT is now talking to airframers and long-haul flight operators about installing its Star equipment on board large airliners.
Installed
An air drying system is installed in the crown of an aircraft, with a humidification system placed at various points around the hull. The system raises humidity in first and business class cabins from 5% to 25% and in economy from 10% to about 15%.
Says Ulf Liljenberg, CTT’s vice-president of sales and marketing: “There is no place on Earth drier than an aircraft cabin. The world’s driest place is Nevada, which is 12%. Medical opinion is that relative humidity of less than 20% is bad for your health”.
By increasing humidity levels, Star helps reduce fatigue and risk of airborne infectious diseases.
