Humidifier Pad Assy by CTT is based on unique IP to obtain OEM compliance

The CTT Systems humidifier pad assy is based on unique IP material to meet the specs from Airbus and Boeing. The Humidifier Onboard pad assy is more than a component, it is a sub-system in the Humidifier Onboard system, that complies with all reliability, performance and safety measures.

Over 3,000 Humidifier Onboard in service

Dry cabin air has been a well-known problem for decades. At CTT Systems, we entered the market over 20 years ago as pioneers by developing a Humidifier Onboard system based on evaporative cooling technology. A few years later, Airbus selected us to provide Humidifier Onboard crew rest compartments for the A380 program.

Boeing followed suit and selected CTT Systems for the 787 program to supply Humidifier Onboard crew rest compartments and flight decks.  At CTT Systems, we continued our winning streak with the sole OEM supply of humidifiers for flight decks, crew rest compartments, and passenger cabins on Airbus A350 and Boeing 777X. Today, we have more than 3,000 Humidifier Onboard in service at over 50 airlines worldwide.

Original humidifier pad assy uses IP material to meet OEM standards

When developing the technology for line-fit, our CTT Systems engineers recognized that existing pad materials failed to meet the stringent standards in aviation, particularly those of Boeing and Airbus, as well as regulations from the FAA and FDA. Commodity material did not comply with rigorous performance and safety requirements in aircraft.

The pursuit of excellence led to a powerful alliance with Munters, the world’s foremost supplier of climate solutions. CTT Systems and Munters engineered a new and unique humidifier pad material that not only met the standards but also surpassed them, setting a new benchmark.

Tailored for aviation standards and OEM humidifier

CTT Systems humidifier pad assy is specifically tailored for aircraft requirements and to co-function with the OEM humidifier housing. Our pad material has been rigorously tested to withstand maximum air velocity, meet carryover limits, and maintain pH levels within stringent technical specifications. The high fire rating, the prevention of legionella transfer, and the use of activated carbon make the humidifier pad assy resistant to bacterial growth.

Another qualification requirement for the pad material was to remain functional under operating conditions specific to the OEM humidifier housing, such as the design to spray water in short intervals, rather than continuously rinsing through the pad, as in other applications. All criteria above cannot be fulfilled by using a commodity pad assy material.

Humidifier pad assy’s part of the air supply

Another area where our humidifier pad material stands out is its ability to safeguard reliability and safety. Since air supply to the flight deck and crew rest passes through the Humidifier Onboard system, the pad material must remain intact and not release any material or collapse. The CTT Systems original humidifier pad assy material complies with the FAA Part 25 and EASA CS-25 airworthiness standards, and even more importantly; the Boeing requirements on design, testing, documentation, etc, ensuring that airflow remains consistent and safe.

Commitment to humidifier pad assy excellence

In summary, the Humidifier Pad Assy from CTT Systems features unique IP material and sets a new standard in aircraft humidification technology, ensuring compliance with all relevant industry standards and aviation authorities. The CTT Systems humidifier pad assy is not just a commodity or a component, it’s a sub-system designed to co-function with the OEM humidifier housing and to secure a consistent flow of humidified air with the highest reliability and best performance. The CTT Systems Humidifier Onboard system has demonstrated outstanding reliability in airline operations since 2007 and is now fitted in nearly 1,500 widebody aircraft.
