What CTT Systems does
CTT Systems AB (publ.) is a Swedish aerospace company founded in 1991 and listed on Nasdaq Stockholm's Mid Cap segment since 1999, headquartered in Nyköping with a manufacturing division (CTT Nybro) in Nybro. The company designs and manufactures active humidity control systems for aircraft, with two core product lines: the Humidifier Onboard system, which generates pure water vapor from the potable tank to elevate cabin humidity from near-desert levels (~3% RH) to 17% in the flight deck and 22% in cabin and crew rest compartments, and the Anti-Condensation system, which removes trapped moisture from aircraft fuselages to reduce weight, fuel burn, and CO2 emissions.
The technology is deployed across multiple aircraft zones via dedicated variants (First and Business Class, Flight Deck, Crew Rest Compartment, VIP/Business Jet) and is supported by an OEM-compliant consumable (Humidifier Pad Assy) that is tested and continuously upgraded over more than 30 years. CTT is the only producer holding the full combination of EASA Part 21 Subpart G (POA), EASA Part 145 (MOA), TCCA CAR 573, FAA Repair Station, UK CAA 145, AS9100:D, and ISO 9001:2015 approvals for this product class.
CTT's revenue is generated through three streams: (i) original equipment sales of Humidifier Onboard and Anti-Condensation systems as factory line-fit options to Boeing (787, 777X) and Airbus (A350), as well as VIP and cargo retrofits; (ii) aftermarket spares and consumables (primarily humidifier pads) distributed globally via SATAIR (four regions) and Boeing Distribution; and (iii) MRO and customer support services. The company reported FY2025 net sales of MSEK 264.4 with operating profit of MSEK 47.5 (operating margin 18%), and a strong Q1 2026 rebound to MSEK 66.1 in revenue (+22% reported, +41% currency-adjusted).
