Sweden-based aircraft humidity control solution provider CTT Systems has announced that it received a zonal drying system order for two Boeing 737-800 aircraft.

CTT Systems provides anti-condensation systems for commercial aircraft and humidification products for cockpit, crew rest and cabin areas.

Boeing will install the zonal drying anti-condensation system to reduce costs during operations generated by excess weight from condensate water accumulation.

Aircraft experience increased fuel burn and emissions due to such weight increase.

"The demand for line-fitted installation of our anti-condensation equipment is growing as more airlines want to master the root-cause of moisture problems."

The zonal drying system will also benefit the airline with other investments such as reducing the failure rate of electrical components or out-of-service time, and replacement of insulation blankets.

The system will be factory installed by Boeing.

CTT Systems sales and marketing VP Peter Landquist said: "This is a repeat order, which is a great recognition from an airline valuing the total benefits of our anti-condensation system.

"The demand for line-fitted installation of our anti-condensation equipment is growing as more airlines want to master the root-cause of moisture problems from the very first day when a new aircraft enter into operations."

CTT products include anti-condensation systems for moisture problems in aircraft, and humidifiers for in-flight comfort and well-being for crew and passengers.

Boeing 787 aircraft’s crew rest compartments are fitted with CTT’s crew humidifier, which is available as an optional extra in other A380 and A350XWB aircraft.

The flight deck humidifier is optional for both the Airbus A350XWB and Boeing 787.

CTT’s Cair humidification was first used by Airbus A350XWB as supplier-furnished-equipment (SFE) for first and business class.

Last month, CTT received a contract to develop a humidifier for a new crew rest compartment on the A380 aircraft. It will be introduced to customers by next year.
