Controlled Ozone Monitor

Do you control the emission of ozone from your extraction system to comply with safe level guidelines?


Are you complying with the current clean air guidelines on the discharging of ozone from commercial kitchen extraction systems?


The Co Monitor controls the amount of ozone being discharged, either at the point of termination of the extraction ducts or in areas that are sensitive to exposure to ozone levels which exceed permitted levels.

Once the monitor detects high levels of ozone it will communicate with the Controlled Ozone Injector to reduce or stop generating ozone until safe levels are reached.


Using a Co Monitor will give long term safeguards from excess ozone.
