Case Study

Using Ozone to Disinfect Aircraft Cabins

In this study, a new method of cleaning the cabins of passenger airplanes was studied. High ozone was pumped into the aircraft's air conditioning system. The 0-100 ppm range of the Model 106-L enabled researchers to monitor the fumigation levels of the ozone as well as the fallback to safe levels. Hospital-grade sterilization was achieved in about 90 minutes of treatment, with the added benefit of the ability of ozone to penetrate the hard-to-reach places on the plane, such as tray tables in the locked & upright position.

The Problem

During the 2020 Coronavirus pandemic, airlines are looking for ways to promote a sterile and safe travel experience for their customers. Current disinfection methods involve using a large crew to deep clean an aircraft at the end of the day. This approach requires a lot of manpower and a huge time commitment considering how many airplanes fly each day.

The Solution

Energy Quest Technologies decided to try a new approach to cleaning airplanes. Energy Quest Technologies is a Chandler, AZ based manufacturer of portable air conditioners. They knew pumping ozone into the plane through its air conditioning system could be the solution. Airplanes are inherently airtight, providing the perfect conditions for ozone treatment.

Energy Quest Technologies, The University of Arizona College of Public Health, and Pima Air & Space Museum experimented on a Boeing 737 to test this approach to sanitizing a plane.

The Results

Ozone treatment allowed for effective disinfection results in a short amount of time. Hospital grade sterilization was achieved in about 90 minutes of treatment. There was a 99.9999% reduction in virus due to ozone treatment. An added benefit was the ability of ozone to penetrate hard-to-reach places on the plane, such as the seat back pockets and tray tables in the upright & locked position.

The Model 106-L Ozone Monitor was used in the development of a new method to clean airplane cabins.  High amounts of ozone were pumped through the aircraft's air conditioning system, and the 106-L monitored the concentration of ozone applied as well as the

The 2B Tech Instrument’s Role

The Model 106-L monitored the ozone concentration throughout the aircraft sterilization process. The portability of the instrument allowed the ozone monitor to be located inside the aircraft cabin during the testing. Here the Model 106-L could measure the concentration to ensure ozone reached a critical level to achieve 99.9999% reduction of virus.

The Model 106-L offers two two-level relays which can be used in a disinfection application to control the output of an ozone generator.

The relay can be programmed to turn off a generator at a set concentration to prevent over-production of ozone. Conversely the relay can be programmed to turn on a generator when ozone concentrations drop below a user-defined set point. This will help ensure the proper amount of ozone is generated to provide efficient disinfection.

Please review the Tech Note on our website for additional information about programming the relays on the Model 106-L.

The Bottom Line

The ability to control the production of ozone combined with the high level of precision, accuracy, and reliability for ozone measurement offered by the Model 106-L make the instrument a simple yet ideal package for any disinfection & sterilization application.

This research investigated how the wavelengths of light emitted by mercury lamps affects radical generation and chemistry in an oxidation flow reactor. Different types of lamps were designed and tested, and the Model 106-M Ozone Monitor measured the ozone concentration at the exit of the flow reactor. Empirical estimation equations could be used to predict the hydroxyl radical production, a much simpler approach than using photochemical models.

Researchers at the University of São Paulo are studying the use of ozone as a more environmentally sound method for modifying the properties of starch. Industrial sectors that use starch include food, petrochemical, adhesives, paints, and others. This study applied high ozone and used the Model 106-H Ozone Monitor to follow the inlet and outlet concentrations of a reactor containing the starch. The study identified several techniques for optimizing starch properties.

Our instruments went out for a spin when researchers at the University of Texas loaded up the back of a hatchback for a study of the physiological effects of air pollution. The study was published in 2022 in the journal Sensors. Included were three instruments from 2B Tech to measure O3, NO2, NO, and black carbon. A tantalizing finding from the study: the biometric measurements themselves were in some cases good “detectors” of particulate matter (PM) pollution.
