CTT Systems develops and supplies active humidity-control systems for aircraft cabins—both humidifiers that raise comfort levels in dry high-altitude air and dehumidifiers that reduce condensation. Based in Sweden, it is a specialist niche supplier to commercial airlines, business jets and aircraft manufacturers, with thousands of units installed. Its technology targets the cabin “humidity paradox” of overly dry air for passengers alongside moisture problems in the airframe.
