Overcome odour issues Reduce grease build up Help reduce maintenance & cleaning
It has long been recognised that 03 gas (Ozone) is a very effective medium of neutralising cooking odours and its injection into kitchen extraction has been successfully used to control odour emissions. There have however been major concerns about the control of safe levels of the ozone emitted from the kitchen extraction system by this method. Recognising these issues, we set about developing a range to safely utilise the benefits of gaseous ozone to control odours whilst controlling the levels of ozone emitted from cooking processes. Ecovery Innovations has been developing their range of Controlled Ozone Generators for eight years following their decision not to supply UV Ozone systems. Early 03 production was via UV Bulbs which emit ozone when turned on, but we wanted to move away from this method because of concerns including; • • • •
The health risk of Arc Eye from exposure to the UV bulb The safety risk of glass powder from a bulb breaking The breakdown of the efficiency of the UV bulb over a six to twelve-month period The inability to control the ozone output level from a UV bulb.
The gaseous ozone produced by the units can be injected directly into the canopy plenum or the early stage of the extract duct, which is not possible with UV Bulbs. UV bulbs must be sited much later into the extraction path because the bulb glass becomes fragile if subjected to the levels of heat that builds up in the plenum and early duct. The benefits of this early injection of ozone is two-fold; • •
The ozone is given longer in contact with the organic particulate from the cooking process to break it down. The ozone reverts quicker at higher temperatures allowing a slightly higher concentration of ozone to be injected into the plenum but still maintain safe levels of emission.
The units are fitted with air pressure switches which are activated by air movement within the extraction system ducts. This ensures they only produce ozone when there is enough air movement within the ducts for the safe injection of the ozone. Our generators have been designed to be safely installed where the discharge point of the extraction is considered to be of low risk and where one unit is sufficient to meet the ozone levels required to neutralise the cooking odours being emitted. For installations where either of these factors are not the case Ecovery Innovations has developed their Controlled Ozone Reactive System. Here we use a control panel to adjust the ozone output over a number of units, using information collected from an air pressure switch and air quality sensor.
