About CTT Systems

CTT is the leading supplier of active humidity control systems in aircraft. We solve the aircraft humidity paradox - with far too dry cabin air - and too much moisture in the fuselage - causing dehydration for people onboard and excess weight in the aircraft inducing larger environmental footprint. CTT offers humidifiers and dehumidifiers available for retrofit and line-fit on commercial aircraft as well as private jets. For more information about CTT and how active humidity control products make air traveling a little more sustainable and far more pleasurable, please visit: www.ctt.se
