Icelandair orders Zonal Drying™ for retrofit on 16 Boeing 757/767, with Options for additional 16 Boeing MAX aircraft

Nyköping 1 October, 2015, CTT SYSTEMS (“CTT”), the market leading provider of aircraft moisture control systems, with fuselage anti-condensation and humidifiers for cockpit, crew rests and passenger cabin areas, today announces order from Icelandair on the Zonal Drying™ System for 14 Boeing 757-200 and two Boeing 767-300, with options for additional 16 Boeing MAX 8/9 aircraft.

The retrofit installation will start with the first 757-200 in December 2015.

“At CTT we are pleased to receive this order from one of our first customers on the Zonal Drying™ System. With this order CTT will add another customer having Zonal Drying™ all-fleet-fitted”, says Peter Landquist, Vice President Sales & Marketing of CTT Systems.

The Zonal Drying™ Anti-Condensation System generates the following advantages:

  • Lower fuel burn and CO2/NOX emissions from excess weight reduction of 200-300kg of accumulated condensate water in B737/A320 aircraft;

  • Higher operational reliability from significant lowered moisture related faults in electrical equipment (reduced Out-Of-Service time)

  • Lower attrition of replacing insulation blankets


CTT Systems is specialized in providing products for humidity control in the aircraft. CTT products include anti-condensation systems for mastering moisture problems in the aircraft and humidifiers for in-flight comfort and wellbeing for crew and passengers. CTT products are offered for retrofit installation and line-fit for A380, A350XWB and Boeing 787. The crew humidifier is standard in all crew rest compartment fitted Boeing 787 aircraft and optional in the crew rest compartment on A380 and A350XWB program. The flight deck humidifier is optional on both the Airbus A350XWB and Boeing 787 aircraft. The Airbus A350XWB is first to offer Cair™ humidification as SFE for First and Business Class (Zone1-3). The Zonal Drying™ anti-condensation system is basic equipment in all Boeing 787 aircraft and optional (as Buyer-Furnished-Equipment) for the Boeing 737NG. Also visit:
