Gas Sensing Solutions' CO2 Sensor Technology Playing Key Role in Government Funded Research Program on Aircraft Cabin Air Quality

03 July 2018

The innovative carbon dioxide sensing technology that has been developed by Gas Sensing Solutions (GSS) will play a key role in a UK Government funded research program to improve aircraft cabin air quality.

The U-CAIR project, led by Honeywell in partnership with the National Physical Laboratory, Gas Sensing Solutions and SST Sensing, is developing cabin air sensor technology to improve passengers' cabin experience. The U-CAIR (UK ATI Cabin Air) project will not only create an improved passenger experience in large passenger aircraft, business jets and regional aircraft, but also allow for further fuel savings of up to 2000 liters on long-haul flights. Receiving a grant of £2.3 million, this project will enable the U.K. to develop key technologies that will lead the market in passenger-friendly aircraft. This is part of the £3.9 billion that government and industry will have committed to the aerospace sector by 2026.

The project is driven by the increasing awareness of the effects that even slightly elevated levels of CO2 can have on health, which start with yawning and drowsiness and become progressively worse as levels rise. If a room feels stuffy that is not due to lack of oxygen but CO2 levels increasing to the point where they are starting to have an effect.

In an aircraft with hundreds of people all breathing out CO2, the level could quickly rise, so the air has to be changed to remove it. Changing the air uses energy to pump low-pressure air in from outside the aircraft, then pressurize and warm it for the cabin. This energy comes from burning aircraft fuel, so the aim of this project is to monitor the level of CO2 in the cabin to match the air change to what is actually required. This can provide significant savings in fuel use and reduce carbon footprints.

Calum MacGregor, CEO of GSS, explained, "Our unique CO2 sensor technology has been selected for this project because of its industry-leading features of low power, accuracy and immunity to vibration. Plus, our sensors are very robust with a long service life, making them the perfect choice for the challenging environment of vibration, pressure changes, etc. in an aircraft where they must work reliably for many years. This project is one of many that we are involved in where we develop a custom solution that precisely meets the needs of the customer."

For more information, have a look at the range of CozIR® CO2 sensors for air quality monitoring. These low power sensors are designed to measure ambient air (up to 1 percent CO2), so they are highly suited to monitoring air quality on aircraft and in similar confined spaces.
