Activated Air Units
From Process Systems
By means of a high-voltage applied to an ultra-violet light generating, catalytic wire mesh, molecules in ambient air are split and energised, converting the moisture and air into a flow consisting of a mixture of unstable atoms, ions and radicals, with elevated electron activity levels. These Activated Air molecules may then be injected into a gas carrying target compounds. The result is the high-rate oxidation of odorous molecules. With this relatively simple but extremely potent technology residual odours may be completely eliminated from the offgas of a wide range of processes. The activated air molecules will attack all oxidisable compounds, reducing them to carbon dioxide, water, nitrogen and other such innocuous substances. The reactions involved are irreversible.
- highly efficient Odour Control by means of the high-rate oxidation of target substances
- no moving parts, mechanical wear, no chemical additions required, no water consumption and no waste products
- low energy requirements
- Flow rates available: 2,000 to 20,000 cubic metres per hour of exhaust gas flow. Larger flows may be accommodated with multiple modules
- Energy requirements: 5 kW hr per 1,000 cubic metres
- Space requirements: The largest standard module occupies a space of 1.5 m wide x 1.0 metre deep x 2.4 metres high. Front access is required for access to controls and for servicing
Deodorisation with an Activated Air unit is based upon high-speed oxidation. Molecules oxidised by this method cannot be detected by the human nose.
An Activated Air unit consists of a stainless steel cabinet containing wide-mesh UV-catalysts. Ambient air is passed through the unit, from atmosphere without any pre-treatment, and radiated.
