CTT Systems Announces Zonal Drying™ Order for six Boeing 737-800s

CTT Systems AB (“CTT”), the market leader of aircraft humidity control systems, announces Zonal Drying™ order for six Boeing 737-800s to be factory installed by Boeing for an undisclosed customer starting in December 2015 and to be finalized in April 2016.

“We are pleased with another order for factory installation at Boeing,” said Peter Landquist, VP Sales & Marketing CTT Systems AB. “We are honored that airlines value the benefits from mastering the root-cause of aircraft condensation/moisture problems from the very first day of its entry into service”.

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
