Boeing deletes CTT Zonal Drying on Dreamliner


CTT Systems, a manufacturer of humidity control systems for aircraft, has announced that Boeing has de-selected its Zonal Drying equipment on the 787. This decision is a consequence of Boeing’s previous decision to remove the Moisture Control system as basic equipment on the aircraft type, and is consistent with other Boeing airplanes utilizing crown ventilation via upper recirculation air. According to CTT, this decision will have financial impact on the company from the end of 2019.

When the decision enters into force the deletion of Zonal Drying OEM equipment will not only will lead to lowered OEM sales, but also will have impact on correlated IP deliveries and aftermarket sales, says CTT. In 2017 and first half of 2018, this in total accounted for 15-20% of CTT Systems’ net revenues.

CTT Systems will remain a supplier for the 787, supporting humidifiers to flight deck and crew rest compartments.

“Although an unwanted change for CTT Systems, our target market for Zonal Drying is primarily single-aisle aircraft,” commented Torbjörn Johansson CEO of CTT Systems. “We are pleased to notice that our humidifiers in flight deck and crew rests are frequently selected on Boeing 787 and highly appreciated amongst pilots and crew.”
