Peter Landquist, VP, Marketing, CTT Systems, explains: “It’s a simple and direct solution, using an evaporation technique. We install a humidifier in the supply duct for the zone that we are going to humidify. We spray water over an evaporation pad in sequence, and you get a cold evaporation. When the air goes through the pad, it evaporates out in vapour into the cabin area.”
CTT started deploying the technology initially in the VIP area because this is the driest area of the aircraft. Landquist said that in fact, in first and business class the humidity level is lower than in the desert and the arctic.
"Everyone knows it's very dry, but not just how dry it is, and of course it has a health aspect. Your mucus membranes dry out; it's easier for the virus to attack you and you catch a cold.”By Peter Landquist, VP, Marketing, CTT Systems
Next the company focused on the flight deck following a request from Boeing and Airbus. Research suggests that flight attendants have significantly more respiratory infections than those who do not frequently fly. The solution is now moving into business class.
Landquist said: "On the A350 and the 777X, our system can be selected for the premium class, first class and business class, and it will also have a positive effect for economy class due to the recirculation system in the aircraft. About 50% of the air is recirculated and evenly divided over the aircraft, so it will have a positive effect for all passengers.”
