Humidifier Pad Assy

The Humidifier Pad Assy from CTT Systems is a groundbreaking innovation, resulting from development, testing and certification together with Airbus and Boeing. The CTT Humidifier Pad Assy uses unique and application specific pad material that was developed to meet all specs and obtain full system compatibility with the OEM humidificaition system. Since the launch of the A380, CTT Systems is at forefront, crafting OEM systems and original pad assy’s to all new widebody programs.

Humidifier pad overview

The Humidifier Pad Assy by CTT Systems ensures 100% OEM compatibility. The pad is inserted into the OEM humidifier housing; and thus a sub-system within the Humidifier Onboard system, that is integrated into the air duct for a specific cabin section; and therefore part of the aircraft Environmental Control System (ECS). Pad failure can compromise the safety and performance, not only of the Humidifier Onboard system, but more importantly impact the air supply to flight deck, crew rests and passenger cabin areas.

Innovative material development

When developing line-fit technology, CTT Systems engineers recognized that standard pad materials did not meet the rigorous aviation standards set by Boeing, Airbus, the FAA, and the FDA. In response, CTT Systems formed a strategic alliance with Munters, a leading supplier of climate solutions, to develop a new and unique humidifier pad material.

Aviation standards and OEM humidifier

The CTT Systems humidifier pad assembly has undergone extensive testing to ensure it can handle maximum air velocity, adhere to carryover limits, and maintain appropriate pH levels. It features a high fire rating, prevents legionella transfer, and incorporates activated carbon to resist bacterial growth. The CTT pad material is developed, tested and qualified to ensure 100% integration and compatibility with the OEM humidifier housing, a capability not achievable with commodity pad materials.

Ensuring reliability and safety

A critical aspect of the humidifier pad material is its contribution to the reliability and safety of the air supply system. As the air for the flight deck and crew rest areas passes through the Humidifier Onboard system, it is imperative that the pad material remains intact, without releasing any particles or collapsing. The original humidifier pad assembly material from CTT Systems meets FAA Part 25 and EASA CS-25 airworthiness standards, as well as Boeing’s stringent requirements for design, testing, and documentation, ensuring consistent and safe airflow. 

Addressing the dry cabin air

 Over 20 years ago, CTT Systems pioneered  by developing the Humidifier Onboard system based on evaporative cooling technology. This innovation was first embraced by Airbus for crew rest compartments on the A380 program, followed by Boeing for crew rests and flight deck on the 787 program. CTT was also selected as the sole supplier of humidifiers for flight deck, crew rests and passenger cabins to the A350 and Boeing 777X program. Today, more than 3,000 Humidifier Onboard systems are in service across over 50 airlines worldwide. 

Conclusion

The Humidifier Pad Assy from CTT Systems represents a significant advancement in aircraft humidification technology. With its unique IP material, it sets new standards in the industry, ensuring full compliance with all relevant aviation authorities and industry standards. The Humidifier Pad Assy is not just a component; it is a crucial sub-system designed to work in tandem with the OEM humidifier housing, providing consistent, reliable, and high-performance humidified air flow. Since its introduction in 2007, the CTT Systems Humidifier Onboard system has documented exceptional reliability and performance in nearly 1,500 widebody aircraft.
