Conventional cleaning involves complex and expensive cleaning at regular intervals using robots, high-pressure cleaners and high-performance chemicals to locate the fat deposits in the ducts and remove them. The conventional way of cleaning can, however, only solve the above mentioned problems in the short term and only partly. Many places in the duct system cannot be reached because, for example, of the lack of inspection hatches. The highly aggressive, high performance chemicals used for conventional cleaning also cause considerable problems especially for older duct systems.
The GIF UV-C(lean) System is the ultimate solution for the decomposing of organic fats and oils in the kitchen extract air by means of UVC-light. Oils and fats are hydrocarbon compounds, the individual molecules of which consist of several carbon atoms, which are linked to one another by single or multiple bonds.
1. When greasy substances are irradiated with intensive UVC-radiation a part of the energy of the UVC-light is absorbed by the fat or oil. The fat molecules are brought into an energetically stimulated state which enables the fat molecules to be oxidised much more quickly.
2. At the same time, ozone is created by the action of the UVC-radiation on the oxygen molecules of the air. The oxidation capacity of ozone is much higher than that of the normal oxygen in the air. These two processes enable the fat molecules to be oxidised immediately (“cold combustion“). The products of the oxidation formed as a result are gaseous, short-chain, organic compounds (e.g. carbon dioxide), which are removed by the extract air stream.
