CTT Systems AB (CTT), a manufacturer of aircraft cabin humidity control systems, has announced an order for 146 Anti-Condensation-systems from an unspecified European airline (likely to be Jet2.com based on fleet), to be retrofitted in 146 Airbus A321neos, with optional purchase rights for additional nine systems.
Based on list price, the total order value is approximately 120 million SEK (US$10.9m) and another 7 million SEK ($0.64m) if all options are exercised. Deliveries of the first 30 systems will commence in Q3 2025 and are scheduled to be completed in 2028. Delivery dates for the remaining order of 116 systems are not yet specified, but CTT states that all deliveries shall be completed no later than 2035. The Anti-Condensation systems will be installed at the first C-check for every aircraft.
The CTT Anti-Fuselage-Condensation system is designed to remove water trapped in insulation blankets between the cabin wall and the outer fuselage skin, keep the crown area dry, and prevent unwanted excess weight from water accumulation.
CTT figures indicate that a 200-300kg weight reduction on an A321neo aircraft generates the following benefits: reducing fuel burn by an estimated 0.4-0.6%; cutting CO2 emissions by approximately 65-95 tons per aircraft per year, with fuel savings of around. 25,000-38,000 litres per year; higher operational reliability due to fewer instances of moisture-related faults in electrical equipment (reduced out-of-service time and repair costs); and a lower rate of insulation blanket replacement.
