It also offers increased protection for ambulance services and public authority vehicles used by different crews. In addition to vehicles, the unit is suitable for use in hotel rooms and business premises.
The new unit from MAHLE uses ozone to purify the air inside cabins and other interiors. To do this, all doors into the vehicle or room must be closed. While the sanitizing process is underway, the OzonePRO sensors continuously measure the concentration of ozone produced in the environment and adjust this until the ideal value is reached. This value is maintained for some time to ensure a hygienic clean. At the same time, OzonePRO avoids excessive ozone values in order to prevent oxidation damage to the interior, for example.
According to bus manufacturer Irizar, which also markets an air cleaner, studies show that the principal danger of COVID-19 infection on buses and coaches is by inhalation of airborne droplets and micro-particles. The presence of increased levels of ozone releases single atoms of oxygen that have a propensity to bond with microscopic particles such as a virus, and destroy them by oxidisation, it said.
The OzonePRO unit can be connected to a cigarette lighter or is available upon request with an additional power supply unit for use in indoor spaces. With an ozone output of 5,000 mg/h, one unit can disinfect interiors with a surface area of up to 40 square meters or of around 100 m3 in volume, roughly equivalent to the volume of a coach. The unit weighs 3kg.
Operation is automated, and the device notifies the user when the disinfection is finished. Vehicles and rooms can then be safely entered again. The entire process can be controlled and monitored externally with the associated O3-Easy app. Once the sanitization process has been completed, a disinfection report can be printed for the customer, if necessary.
