CTT Systems Announces Zonal Drying™ Order for 9 Boeing aircraft

CTT Systems AB (“CTT”), the market leader in aircraft humidity control systems, announces Zonal Drying™ order for additional 2 Boeing 757-200s and 7 Boeing 767-300s to be retrofit installed by AZUR Aviation. Delivery from October 2017 to first quarter 2018.  

Peter Landquist, VP Sales & Marketing, CTT Systems AB, comments: ‘We are privileged to receive an additional order from AZUR Aviation, now with proven system effectivity from previous installation and valuing the benefits of mastering the root-cause of fuselage condensation. Hereby, the new aircraft will not gain weight from accumulated water/ice accretion (which increasing fuel and CO2 burn) and it will not experience moisture problems, such as electrical failures, which increase cost.’ 

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 water in B737/A320 aircraft;
  •  Higher operational reliability from significantly lower moisture related faults in electrical equipment (reduced Out-Of-Service time).
  •  Lower rate of insulation blanket replacement.


CTT Systems is the market leading provider of humidity control products in aircraft, including anti-condensation systems preventing moisture problems in the aircraft and humidifiers for in-flight comfort and wellbeing for crew and passengers. Our products are offered for retrofit installations and line-fit on A380, A350XWB, Boeing 787 and Boeing 777X. The crew humidifier is standard in all crew rest compartment fitted Boeing 787 aircraft and optional in the crew rest compartment on A380, A350XWB and B777X program. The flight deck humidifier is optional on both the Airbus A350XWB, Boeing 787 and Boeing 777X aircraft. The Airbus A350XWB is first to offer Cair™ humidification as SFE for First/Business Class (Zone1-3) and the Boeing 777X is the second to offer Cair™ humidification as SFE for First/Business Class (Zone1 and 2). The Zonal Drying™ anti-condensation system is basic equipment in all Boeing 787 aircraft and optional (as Buyer-Furnished-Equipment) on the Boeing 737NG program. Also visit: www.ctt.se
