CTT Systems releases two Zonal Drying™ orders of total eight Boeing Next-Generation 737-800s

CTT Systems AB (“CTT”), the market leader in aircraft humidity control systems, announces two Zonal Drying™ Buyer Furnished Equipment orders for a total of eight Boeing Next-Generation 737-800 aircraft. The eight Zonal Drying systems will be line fitted by Boeing from December 2017 to December 2018.

Peter Landquist, VP Sales & Marketing, CTT Systems AB, comments: “We see an uptick in airline demand for our Zonal Drying system, mainly driven by higher passenger load-factors and from high-density seat layouts. Several airlines that increased seat capacity by adding more seats now experience moisture problems from condensation due to insufficient support from built-in, passive drainage solutions. More airlines recognize the importance to master condensation. These airlines are not only committed to cut fuel consumption and emissions, but also looking for ways to improve reliability in equipment and in its operations.” 

The Zonal Drying system removes trapped water in blankets, keeps the crown area dry and prevents unwanted excess weight from water accumulation. Hereby, on every flight airlines can operate with lower energy needs and less pollutant emissions. Lowered excess aircraft weight of 200 kg, reduces block fuel consumption by around 0.4%, resulting in fuel savings of approx. 25,000 liters per year per aircraft, cutting carbon dioxide emissions by more than 65 tons. Additional costs savings comes from lower repair costs of moisture related damages in electrical components and equipment, repair/replace of blankets and reduced down-time due to electrical failures.

The Zonal Drying™ system generates the following advantages:

  •  Lowers fuel burn with 0.4%-0.6% and CO2 emissions with some 65-95 tons per aircraft per year from excess weight reduction of 200-300kg of accumulated water in Boeing 737-800/A320 aircraft (fuel savings of 25,000-38,000 liters per year);
  •  Higher operational reliability from significantly lowered moisture related faults in electrical equipment (reduced Out-Of-Service time and repair costs).
  •  Lower rate of insulation blanket replacement.
