Honeywell Introduces Next-Generation Catalyst To Address 'Smell In Cabin' Events

Rhea-AI Summary

Honeywell (NYSE: HON) has launched a new catalyst, CHOC4, for aircraft cabin air systems. This fourth-generation technology aims to reduce undesirable odors caused by volatile organic compounds (VOCs) in bleed air, potentially saving airlines up to $50 million annually in flight disruptions and unscheduled maintenance. CHOC4 outperforms existing solutions by removing 2 to 3 times more VOCs and effectively handling ozone at lower temperatures. Initially available for Airbus A320, it will expand to other aircraft platforms in 2021.

Positive

• Launch of CHOC4 catalyst for aircraft cabin air systems.
• Capability to remove 2-3 times more VOCs than existing solutions.
• Potential annual savings of up to $50 million for airlines.

Negative

• None.

PHOENIX, Dec. 1, 2020 /PRNewswire/ -- Honeywell (NYSE: HON) has unveiled a new catalyst designed for aircraft cabin air systems that can help reduce delays, cancellations and unscheduled maintenance due to in-cabin odors from certain volatile organic compounds in "bleed air" — also known as undesirable "smell-in-cabin" events. In clinical tests, Honeywell's fourth-generation Combined Hydrocarbon Ozone Catalyst, CHOC4, has proved capable of removing two to three times more VOCs that cause undesired odors compared with other solutions. Honeywell's solution has also been shown to be more effective in the removal of ozone at lower temperatures.

Air supplied to a cabin for air conditioning and pressurization, also known as bleed air, comes directly from the engines and auxiliary power unit. Sometimes it contains volatile organic compounds (VOCs), fumes or particles from sources like jet fuel, hydraulic oils or de-icing fluid. When VOCs enter the cabin through the bleed air, they can cause unwanted odors in the cabin, resulting in delays.

"Severe smell-in-cabin incidents can cost airlines up to $50 million per year in flight disruptions and unscheduled maintenance," said Tom Hart, vice president and general manager, Air & Thermal Systems, Honeywell Aerospace. "CHOC4 reduces VOCs from the engines and bleed air supply, thereby reducing the severity and frequency of these incidents."

Honeywell's new proprietary catalyst CHOC4 is applied to an aircraft's ozone converter to catalyze or absorb compounds that cause undesirable odors. It can be applied during normal maintenance as an upgrade to the existing converter unit at a fraction of the cost of a new unit. It is available now for Airbus A320 aircraft, with plans to expand to additional platforms in early 2021.

Thousands of passenger, cargo and military aircraft worldwide are currently flying with Honeywell environmental, air and thermal systems on board. Now, Honeywell is using its decades of experience developing cabin air-management systems to help improve in-flight comfort.
